=AMC  10.40  (2008-04-10)=
+
===Debounce of ON/OFF hook signalling from ATLB===  
 +
To to reduce unintended resetting of conversation/ringing a debounce function was added to AMC. <br />
 +
But due to delay in signaling from the ATLB card this function is not useful in most situations.
 +
Nvram flag: ex_profile.flags.HOOK_debounce = 1
 +
===Support for two OPC servers===
 +
Two OPC servers can be connected simultaneously to the same AlphaNet. (OPC server software supporting dual OPC needed)

=== Issue 3326 IP master use of "7638" mail call back===
+
===Broadcast flooding in multi node AlphaNet===
−
The "7638" function is now working also from the IP master station
+
During reset of AlphaCom with alpha_sys versions from 1043x to 1053 CANCEL_MAIL AlphaNet messages from trunk-proxy stations are sent as node broadcast.<br />
−
=== Issue 3333 IP substation volume control fails ===
+
The number of trunk-proxy stations are dependent on IP links plus the configuration of AE1 and AGA AlphaNet links.<br />
−
Setting of volume with DP message now works for IP stations
+
In an multi node AlphaNet IP configuration with all nodes communicate to all other nodes a broadcast will go from the origin node to all other nodes. The "other" nodes will then send the broadcast to all other nodes except for the node from where the broadcast was received. <br />
−
=== Issue 3341 Master IP and Ringing Group ===
+
A table of unique reference for each broadcast is used for throwing away broadcasts already received. <br />
−
Call request queue on IP master with different priorities, ringing group and call req now works.
+
If the number of active broadcast is higher than the size of the broadcast reference table in combination of some AlphaNet links with delay, nodes can start resending "old" broadcast. This can reach an amount of messages that makes the AlphaCom software watchdog activate a reset generating lots of new CANCEL_MAIL broadcast, then a situation of cyclic reset of all nodes can occur.  
−
=== Issue Inquiry/transfer ===
+
To avoid this problem the following improvements are made:
−
Possible lockup state during faulty use of inquiry/transfer removed.
 
−
=== Audio quality problems with max number of voip channels in use ===
 
−
DSP SW optimized, 31 active VoIP channels now works without distortion.
 
−
 
 
−
 
 
  
−
== Functional changes / Enhancement ==
+
*Remove broadcast of CANCEL_MAIL from proxy station after reset.
−
=== Default use of TCP-IP with Simple Linklayer between AlphaCom nodes in AlphaNet ===
+
*Avoid full TCP sockets blocking the InterCom application software thus making the software watchdog reset.
−
Description : [[Data_link_layer#Selecting_data_link_layer_between_IP_nodes]]
 
−
=== IP station enhancement ===
 
−
* IP station tones during call request mode and "notify" are now generated in the IP station.
 
−
* ON/OFF hook state support for IP master station
 
−
=== ATLB stations and SIP ===
 
−
Allow ATLB stations to use R-key (Flash key) during call to SIP. (Do inquiry and transfer).<br\>
 
−
ATLB12 cards currently not support R-key. (ATLB-6 cards works).
 
−
=== DAK programming from station ===
 
−
When programming a global number (feat 83) the destination node type is checked.
 
−
* SIP node or "collect N digits" programmed allow extra digit being programmed, accept with M-key.
 
−
* Destination node AlphaCom behave as AMC 8-9.

==Errors Corrected==
 +
==={{Bugzilla|155}} Slave missing in multimodule blocks inter-module calls===
 +
Now if a slave is missing other slaves can still receive calls.
 +
===Call between slaves does not seize license in Master===
 +
Call between two slave [[Module|modules]] wrongly seized a [[licenses|license]] in the master in addition to the correct licenses in each of the two slaves.
 +
==={{Bugzilla|159}} Double DTMF signaling from ATLB12 in combination with SIP trunks===
 +
Now both ATLB-6 and ATLB-12 is configured for reporting of signalling during conversation to AMC. <br />
 +
This is done to be able to do digit signalling to Billing when the SIP-TRUNK is connected. <br />
 +
The digit signalling is filtered out in AMC to avoid SIP_INFO being sent to the SIP gateway making double set of DTMF tones.<br />
 +
To avoid double DTMF problems on PNCI the MPC data is also filtered from ATLB during conversation.
  
−
== Errors Corrected ==
+
==={{Bugzilla|162}} Display text update with Billing and alternative trunk===
−
=== Issue 3213 Reset when 7820 backup ===
+
When Billing alternative trunk is activated after pin code dialling, the trunk name is updated in the display of the station.  
−
Backup could crash due to overuse of system resources. The backup/restore function is optimized.
+
===ACDP message DELETE_MAIL could generate reset===
−
=== Issue 3274 and 3320 IP Program distribution and mixed Multi Module with E7/E20/E26 ===
+
$DELETE_MAIL with station parameter resolving to an illegal physical number will now give an ILLEGAL_PARAM instead of reset.
−
Combination of E7 / E20 / E26 program distribution will only work with prog.dist over IP.<br\>
 
−
Remember to open the RTP voip ports in AlphaWeb IP filters !
 
−
=== Issue 3278 Missing first digit in display when node number is 15 ===
 
−
Low level function bug related to node numbers ending in 0x0F (HEX), 15,31,47, 63 etc.  
 
−
=== Issue 3324 $ALRM to IP station ===
 
−
Assert when disconnecting $ALRM to IP stations.
 
−
=== Issue 3338 Time setting "785" and AlphaPro ===
 
−
Local time setting is now changing local time and not UTC time.
 
−
=== Issue 2758 Serial communication via Eth ===
 
−
Using 485 multidrop protocol can cause communication errors both on serial adapters and when connected directly to the AMC serial port.

== Functional changes / Enhancement ==
+
==Functional changes / Enhancement==
−
=== Treble preemphasis adustment of all IP audio ===
+
===Increased Software Priority on the IP station communication===
−
IP audio connections in AlphaNet are not compatible with earlier versions of AMCD SW. This is because  treble preemphasis of AlphaCom audio is now removed when converted to IP/RTP. This change is done in order to improve audio compatibility with IP stations and third party devices. When calling between AlphaCom with old and new SW, audio is connected, but the treble will be too low in one direction, and too high i the opposite direction. Beside not sounding right, the voice switched duplex failes to work properly, requiring extensive use of M-key.
+
To avoid internal buffers overflow in systems with a large number of IP stations the communication to IP stations has been given higher priority
 +
===New Event Handler Macros "[[%25lbd|ldb]]" and "[[%25prog|prog]]"===
 +
Event handler macro "%lbd" for reading out local board number. Typical used for dual AMC configuration.  
 +
Event handler macro "%prog(st_ind)" for reading out current program number 1->xx active on a station. Return 0 if no program active.
  
−
=== External VoIP audio gain adjustment ===
+
===Private Ringing Tone in IP stations===
−
[[IP audio Gain adjustment]] options. Gain towards SIP devices is now by default +18db, giving more appropriate audio level towards external exquipment.
+
Private ringing sequence in IP stations is now completely handled in the IP station to avoid AMC load when hundreds of IP stations is ringing in parallel. <br />
−
=== Multicast reachability test ===
+
IP stations with AUDIO event of type "Private ringing" related to the stations are still handled by AMC to obtain synchronous event state handling with the ringing tone.
−
* IP station multicast reachability tests (mping), with reporting to syslog.
+
===Better performance of IP station PING command===
−
* IP station not receiving RTP audio after connect, error forwarded to syslog.
+
Optimized IP station PING-PONG system. Equal functionality.
−
=== Fader support in IP only system ===
+
===Mail pool increased to 2500 mails===
−
Use AMC-IP FPGA for [[Fader Resource]]. Allowing Groupcall and Simplex conference in "IP only" system.
+
Mail pool is increased from 1104 to 2500 mails. (Nvram state is changed)
−
=== Extended SIP-DTMP signaling ===
 
−
* Outgoing call to SIP: DAK 2 - 5 sends DTMF signals A - D.
 
−
=== Pager support for 8 Bit Ascom ESPA protocol ===
 
−
Support Norwegian character to paging. [[ASCOM_Norwegian_Character_Mapping | Ascom Norwegian Characters]]
 
−
=== OPC server license support ===
 
−
License for connection of OPC server supported.
 
−
=== Global Conference Lockup Situations ===
 
−
Bug fix related to global conference, node reset, default speaker conflicts and resource lockup.
 
−
=== DECT station lockup ===
 
−
Robust handling of call termination to avoid lockup of ATLB stations.
 
−
=== Improved update of Watchdog ===
 
−
Reset due to false watchdog timeout fixed.

=AMC  10.30  (2008-01-17)=
+
==={{Bugzilla|148}}Incoming Call from SIP with different ringing tone===
 +
Added new nvram flag ".ex_profile.flags.trunk_alt_priv_ring". When set to "1" all calls from SIP trunks will use "UK style ringing tone".
  
 +
===Avoid signalling fault from analogue sub stations===
 +
From substations a short press on ID + M can be signalled as ID. When the global flag: "ID_and_IDM_to_IDC_CRM" is set, wait for 300 ms before ID is accepted.
 +
==={{Bugzilla|147}} Muted busy tone removed from SIP trunks===
 +
SIP stations/trunks does not get the muted busy tone (Same behaviour as PNCI system)
 +
===Start of ATLB-ATLB conversation no need for duplex resources===
 +
When starting a call between two local ATLB stations no duplex resources are allocated. <br />
 +
When incoming call from SIP to ATLB no duplex resources are allocated.<br />
 +
This will give the possibility for setting up calls in system with only ATLB12 cards.

===Double syslog call statistics for multi module===
−
 
+
When calling from AlphaNet IP to stations on a IP slave module the call statistic would give 2 entries, the second entry with corrupted data.
−
=== Issue 3149: Follow Me(72) and User/Phy number ===
+
Double lines could also be generated when calling from AlphaNet IP to IP stations.
−
There was a mix of user and physical number in the follow me function. Stations with different physical and user number would  not have correct follow me behavior.
 
−
=== Issue 3157: Call Request Transfer to Phone ===
 
−
Call request forwarding is solved by the new feature [[Call_Request_forward_by_search_strings|Call request forwarding by search strings]]

=== Issue 3210: AlphaNet- CRM4 - display call request ===
 
−
The calling party’s number is not displayed when answering the call request (or MST mail) from a CRM IV type station in another node (AlphaNet). Only the name is shown. The error is only when the answering station has the Station Type set to "CRM 3&4" in software. Fixed.
 
−
=== Issue 3214: $CANM with source as global number ===
 
−
The $CANM can now use global number as source without adding the specific node number (use L2345 in stead of L(2)2345)
 
−
=== Issue 3225: IP substation: Call Req Mode - LED ===

−
=== Issue 3233: No Line error if Hot-line enabled ===
 
−
The flag ''ignore_st_down_in_conv'' allow stations to fail during conversation. For hot line station it means that if hot line is trigged during station down it will not be reported. Fixed by setting a short timeout on how long station can be down when active
 
−
=== Issue 3238: Hanging audio links to SIP/RMD ===
 
−
When initiating a call to SIP/RMD from AlphaCom and terminating during setup tone the Audio connection is not disconnected. Fixed.
 
−
=== Issue 3240:Ringing group - Loose CR mode when called ===
 
−
When in call requester mode, you can be called by anybody, which will take you out of call requester mode.  It will be confusing if you expect your call to be answered and all of a sudden somebody else gets through. There should be a mechanism that when in call requester mode you can only be called by a station which has you in the queue. This is fixed by setting the caller in busy state and use automatic call override when answering from a ringing group.
 
−
=== Issue 3247/3252: AlphaCom uses duplex algorithm when conversation with Ring Master ===
 
−
The duplex algorithm is no longer used on AlphaCom side when calling/called by Ring Master.

−
*[[CANCEL_MAIL]] allowed LV in destination field
+
===[[ST_BUSY_BC]]/[[ST_FREE_BC]] broadcasts for AlphaNet audio lines (proxy)===
−
=== Global Conference ===
+
The [[ST_BUSY_BC]] and [[ST_FREE_BC]] messages now use [[NRF_LOCAL_ENTITY]], in order to avoid confusion with the corresponding events from the end-stations for AlphaNet calls. 
−
New fixes and adjustments
+
===Codec handling for incoming calls from SIP===
−
* Regular interval Root of conference broadcast message was not sent in all situation. (A safety message for reconnecting if links have been down etc)
+
Don't force to codec set in node-profile. Just use best codec offered in INVITE.  
−
* The interval of Root of conference broadcast message is now decreased from 1 hour to 1 minute. It means reconnecting of missing nodes and cleaning of unused links will be much faster after certain network/reset problems.
+
===Paging queue improvements===
−
* Useless single AlphaNet audio links to root nodes with no conference members are cleared.
+
Allow several simultaneous calls to same receiver, so that a unacknowledged call does not block new calls to same receiver.  
−
* When Root of conference is AMC 8/9 and there is an IP transit node with members of the conference, leaf IP nodes was not  able to connect to the conference due to CODEC selection failure.  
+
===ISO 1745 linklayer improved===
−
* Better terminating algorithm when a conference only consist of default members (in several nodes).
+

 +
Previously implemented delay of messages to the ASVP card also delayed the VoIP setup time.
 +
===Stability improvement for IP multi module calls===
 +
===Implemented ping-test of analog PrisCom station processor===
 +
"Cellstation" flag must be enabled. Every PrisCom station are tested in combination with the extended line test timer. (IND 99 is sent to the station and IND ack suspected as reply.) If no reply for two tests the station is reported down to ERR and event handler. However the station is still in active state. (1052x213)
 +
===High availability system, IP station down test===
 +
If there has been connection to a configurable number of IP stations (op_constants(0).sbm_ip_st_down_trig) and all IP station connections are lost: set the standby request flag. (1052x213)

+
===Issue 3333 IP substation volume control fails===
−
Duration is in tenths of second. If Duration parameter is present, and non-zero, the RCO state specified in previous parameter lasts for the specified time. After the time has expired, the RCO is toggled to the opposite state. If a new $SLRC/RCO on the same RCO arrives while the pulse timer is running, the timer is cancelled, and the new message determines the new RCO state. Duration = 0 means infinite duration.<br\>

 +
The log can be stored on on-board flash, or sent over the network with different protocols.
  
−
== SIPD 01.02 upgrades and corrections ==
+
==Known Issues==
−
=== Event “Conversation Outgoing” : ===
 
−
Outgoing calls to SIP: Report Event “Conversation Outgoing” (8) ON when receiving SIP 200 OK, reports OFF at disconnect. <br\>
 
  
−
=== CANCEL_MAIL: ===
+
===Large log files on on-board FLASH===
−
Outgoing calls to SIP: Send CANCEL_MAIL for outgoing call, which cancels call request from that SIP phone.<br\>
+
The log is stored on a limited sized Flash partition by a file system. Routines to handle larger log amounts, like automatic clean up of older files have been implemented, but we still experience problems if the log rates get to large. These problems occur before a theoretical log rate versus free space analysis, mainly because of file system issues with a small number of available flash sectors. This file system factor makes it difficult to make an accurate estimate of handled log rates so the following is based on experience:
 +
 +
Limits:
  
−
=== Events for digits from called SIP: ===
+
Log rates lesser than 1440 events a day (an average of one each minute) should be handled with no problem.
−
Outgoing calls to SIP: If called phone presses digits which are sent to AlphaCom as SIP INFO, "Event Trigger Feature" (15) is reported. The digit is sub event (0-9, * = 10, # = 11). Calling AlphaCom station is Event Owner, and called SIP phone number and node number is related to. This could be used for e.g. Dooropening.<br\>
+
Log rates of 17280 events a day (one each 5th second) is experienced to give problems.
  
−
=== Dialing after initial connect sent as SIP INFO: ===
+
Guideline:
−
Outgoing calls to SIP: Digits dialed after initial connect are forwarded as SIP INFO digit messages to the remote SIP device. This can be used for two step dialing from AlphaCom to an external system, or to the PSTN.<br\>
+
 +
If you are above 1440 events a day you should evaluate to use the Remote Syslog option, and turn off the Local Filesystem Log.
 +
If you are closer to the 17280 events log rate we strongly advise to use only the Remote Syslog option.  
 +
If your system are logging above the 1440 events a day to the filesystem you should regularly monitor the logs.
  
−
=== Register from port different than 5060 allowed: ===
+
Note:
−
Call to SIP: Use port-number stored in registry for contact. Allows SIP device to register from any (random) port, not just 5060. Fixes issue with XLITE 3.0.<br\>
 
  
−
=== Registrar, remove all bindings: ===
+
From AlphaCom 10.23 a log limiter on the System and Debug log is implemented, allowing for a maximum of 60 events a hour.
−
Store only one binding for each user. Remove binding if expires==0. Fixes failure if SIP device registered again from different address/port<br\>
+
If this limit  is reached, it will be notified by a log message. Because of this limit the above guidline will only apply
 +
to the Statistics log.
  
−
=== SDP media description: ===
+
=Hardware Drivers=
−
Call from SIP: handle that SDP a= missing, use m=... Fixes issue with XLITE 3.0.<br\>
+
<br />
 +
==Rtpdaemon==
 +
/opt/amc/bin/rtpdaemon
 +
Rtpdaemon is a user mode service which handle the RTP audio streams. It receives control commands from the AMCD main application on a control socket (/tmp/rtpd). Rtpdaemon transfers and receives RTP packets via standard Linux network sockets. Rtpdaemon packs and unpacks RTP packets. Received packets are buffered before play out. It transfers and receives serialized audio data to the DSP via a DSP driver.<br />
  
−
=== Issue 3059: SIP response handling, call to SIP: ===
+
'''Version 01.09  (2009-11-06)''' <br>
−
Call to SIP: Improved handling of non-successful SIP responses 300->699: Forward response to AMCD followed before proper disconnect of call towards AMCD. Finally SIP ACK is now sent.<br\>
 
−
This allows AMCD to handle busy SIP phone properly, and avoids retransmissions from SIP phones due to missing the ACK.
 
−
Forward 1xx invite responses to AMCD, instead of sending a faked 180 ringing directly on AudioPathSetup from AMCD. Fixes issue with short ring tone when two-step dialing to a SIP gateway.<br\>
 
  
−
=== Call on Hold from SIP: ===
+
*{{Bugzilla|164}} rfc4733 (rfc2833) DTMF in RTP support.
−
When receiving a re-INVITE, respond with 488 not acceptable here.  
 
−
Quick fix of problem that X-lite was not able to disconnect a call if the call was put on hold by pressing other line button.<br\>
 
  
−
=== Display name: ===
+
'''Version 01.08:''' 2009-09-30 <br>
−
Outgoing calls to SIP: don’t send STATION_INFO to AMCD if called name not received from SIP. Fixes issue with blank upper display line for outgoing calls.<br\>
 
  
−
=== Issue 3058: Default route was required: ===
+
*General interface for plugin childprogram, support for ASVP functions.
−
Fixed failure in IP address lookup if default route not defined for the system, even if no routing was required.<br\>
 
  
−
=== Crash fixes: ===
+
'''Version 01.07:''' 2009-08-12<br>
−
Fixed memory crash if SIP 1xx response received out of context. Fixed crash if receiving REGISTER with more than 9 digits in user name<br\>
 
  
−
=== SIP Debug/Trace: ===
+
*Preliminary support for playout of wavfile, via plugin childprogram
−
SIP trace/debug console on UNIX socket /tmp/sipd_trace. Connect using "tst -s /tmp/sipd_trace" from local shell. Possible to change trace level during runtime, press digits 0-7. Default level is 4, which prints SIP and AlphaNet messages. Press 0 to stop tracing. Formatting of message trace improved.<br\>
 
  
−
=== SIPd crash debug: ===
+
'''Version 01.06:''' 2007-12-10<br />
−
If SIPD crashes due to segmentation violation, a short debug message is printed to “/var/log/sipd_crashes”. Only the last crash is recorded, to avoid filling up the file system.<br\>
+
Description: <br>
  
−
=== Issue 3007: SIP - digit during connection: ===
+

=Log System (Syslog)=
+
'''Version 01.21  (2009-08-04)''' <br>
−
<br\>
 
−
The logging is handled by the syslog-ng log daemon. This can be configured to route the logs to different media.
 
−
The log can be stored on on-board flash, or sent over the network with different protocols.
 
  
−
==Known Issues==
+
*{{Bugzilla|223}} , Segmentation fault when Display name over 20 byte received from SIP
  
−
===Large log files on on-board FLASH===
+
'''Version 01.20 (2009-06-22)''' <br>
−
The log is stored on a limited sized Flash partition by a file system. Routines to handle larger log amounts, like automatic clean up of older files have been implemented, but we still experience problems if the log rates get to large. These problems occur before a theoretical log rate versus free space analysis, mainly because of file system issues with a small number of available flash sectors. This file system factor makes it difficult to make an accurate estimate of handled log rates so the following is based on experience:
 
−
   
 
−
Limits:
 
  
−
  Log rates lesser than 1440 events a day (an average of one each minute) should be handled with no problem.
+
*Various fixed in "sip-as-station" JSON interface
−
Log rates of 17280 events a day (one each 5th second) is experienced to give problems.
 
  
−
Guideline:
+
'''Version 01.19 (2009-06-04)''' <br>
−
 
−
If you are above 1440 events a day you should evaluate to use the Remote Syslog option, and turn off the Local Filesystem Log.
 
−
  If you are closer to the 17280 events log rate we strongly advise to use only the Remote Syslog option.
 
−
If your system are logging above the 1440 events a day to the filesystem you should regularly monitor the logs.

*JSON based interface for incoming INVITE and REGISTER, for "sip-as-station", first alpha version
  
−
From AlphaCom 10.23 a log limiter on the System and Debug log is implemented, allowing for a maximum of 60 events a hour.
+
'''Version 01.18 (2009-03-30)''' <br>
−
If this limit  is reached, it will be notified by a log message. Because of this limit the above guidline will only apply

Rtpdaemon is a user mode service which handle the RTP audio streams. It receives control commands from the AMCD main application on a control socket (/tmp/rtpd). Rtpdaemon transfers and receives RTP packets via standard Linux network sockets. Rtpdaemon packs and unpacks RTP packets. Received packets are buffered before play out. It transfers and receives serialized audio data to the DSP via a DSP driver.<br\>

The pin out for RS422 signals on the filter print for E20 and E26 differs from the pin out on the E7. The Rx+ is switched with the Rx- and the Tx+ is switched with the Tx-. The only consequence is that the same cable can't be used on E7 and the E20-series. From filter print version 3 (DB8001/3) the mapping is correct.<br\>

Previous Release - AlphaCom 10.xx - Release Notes

Next Release - AlphaCom 10.6x - Release Notes

This document provides the release notes for AlphaCom 10.4 with incremental bug fix releases. The release notes for AlphaCom 10.4 describe new features, improvements and issues fixed after AlphaCom 10.

Software in production: AMC 10.20
Software released date: 2007-04-12
Note 1: We sometimes do bug fixes in older versions while working with a new version. You can’t read the list version by version, and always assume that a correction is included in the next. Be aware of high release numbers, e.g. 06.05 vs. 07.01. Check version dates, and also comments for each version.
Note 2: For each software version the NVRAM version is listed. If the NVRAM version is different, the AMC board must be cold started, and then you must do a SendAll from AlphaPro to restore the configuration.

BZ 92 Speech from other conversation when calling IP trunk line

When calling an IP trunk line from an IP or SIP station. During call set-up there could be some ms of audio from an other used IP trunk.

BZ 119 Event Handler - Received mail go OFF before Conversation goes ON

When answering a call request the Conversation event (07 or 08) did go ON before the Received Mail event (10) goes OFF. This caused some problems when for instance using these events for CCTV control.

BZ 174 Ringing to SIP times out after 41 seconds

It was not possible to increase timeout on ringing to SIP beyond 41 seconds.

BZ 195 Event trigger feature 52 or 85 from SIP phone doesn't cancel

There was some issues when call request search was used for forwarding regular "623" call requests.

Reactivation of active call request could send mail to wrong queue station

If several simultaneous call request are activated and reactivated to different groups or queue station, a call request could end up in both the correct and a unintended call queue.

PrisCom DAK acknowledge from station could generated "DAK_as_RCI" event OFF

Chilly reset of slave module

Chilly reset of slave modules in nodes with the "copy nvram to slaves" option active would not restart in slave mode without doing a factory reset

14 &963005 .module_profile.node_profile[70].max_trunks = 1 (0x01)
(Default 0 = no limit)

AlphaPro support pending.

Debounce of ON/OFF hook signalling from ATLB

To to reduce unintended resetting of conversation/ringing a debounce function was added to AMC.
But due to delay in signaling from the ATLB card this function is not useful in most situations. 

Nvram flag: ex_profile.flags.HOOK_debounce = 1

Support for two OPC servers

Two OPC servers can be connected simultaneously to the same AlphaNet. (OPC server software supporting dual OPC needed)

Destination SIP IP address shown in node list in AlphaWeb

SIP trunk IP address now also shown when multiple SIP trunks are configured (previously shown as "transit").

Station flag2 bit 12 is used for disabling OPC reporting and OPC license use on station

AMC 1054(2009-06-04)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 10.50.

System upgrade file:
alpha_sys_10_54.tbz2

alpha_sys_10_51.tbz2 must be installed.

AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.

Errors Corrected

Broadcast flooding in multi node AlphaNet

During reset of AlphaCom with alpha_sys versions from 1043x to 1053 CANCEL_MAIL AlphaNet messages from trunk-proxy stations are sent as node broadcast.
The number of trunk-proxy stations are dependent on IP links plus the configuration of AE1 and AGA AlphaNet links.
In an multi node AlphaNet IP configuration with all nodes communicate to all other nodes a broadcast will go from the origin node to all other nodes. The "other" nodes will then send the broadcast to all other nodes except for the node from where the broadcast was received.
A table of unique reference for each broadcast is used for throwing away broadcasts already received.
If the number of active broadcast is higher than the size of the broadcast reference table in combination of some AlphaNet links with delay, nodes can start resending "old" broadcast. This can reach an amount of messages that makes the AlphaCom software watchdog activate a reset generating lots of new CANCEL_MAIL broadcast, then a situation of cyclic reset of all nodes can occur. To avoid this problem the following improvements are made:

  • Remove broadcast of CANCEL_MAIL from proxy station after reset.
  • Avoid full TCP sockets blocking the InterCom application software thus making the software watchdog reset.

BZ 193 Bugfix of search type call request when receiver station is busy

AMC 1053(2009-03-23)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 10.50.
New State Data structure. When upgrading all state data will be lost. (A Chilly start of AMC-IP will be preformed)

BZ 155 Slave missing in multimodule blocks inter-module calls

Now if a slave is missing other slaves can still receive calls.

Call between slaves does not seize license in Master

Call between two slave modules wrongly seized a license in the master in addition to the correct licenses in each of the two slaves.

BZ 159 Double DTMF signaling from ATLB12 in combination with SIP trunks

Now both ATLB-6 and ATLB-12 is configured for reporting of signalling during conversation to AMC.
This is done to be able to do digit signalling to Billing when the SIP-TRUNK is connected.
The digit signalling is filtered out in AMC to avoid SIP_INFO being sent to the SIP gateway making double set of DTMF tones.
To avoid double DTMF problems on PNCI the MPC data is also filtered from ATLB during conversation.

BZ 162 Display text update with Billing and alternative trunk

When Billing alternative trunk is activated after pin code dialling, the trunk name is updated in the display of the station.

ACDP message DELETE_MAIL could generate reset

$DELETE_MAIL with station parameter resolving to an illegal physical number will now give an ILLEGAL_PARAM instead of reset.

Functional changes / Enhancement

Increased Software Priority on the IP station communication

To avoid internal buffers overflow in systems with a large number of IP stations the communication to IP stations has been given higher priority

New Event Handler Macros "ldb" and "prog"

Event handler macro "%lbd" for reading out local board number. Typical used for dual AMC configuration. Event handler macro "%prog(st_ind)" for reading out current program number 1->xx active on a station. Return 0 if no program active.

Private Ringing Tone in IP stations

Private ringing sequence in IP stations is now completely handled in the IP station to avoid AMC load when hundreds of IP stations is ringing in parallel.
IP stations with AUDIO event of type "Private ringing" related to the stations are still handled by AMC to obtain synchronous event state handling with the ringing tone.

Better performance of IP station PING command

Optimized IP station PING-PONG system. Equal functionality.

Mail pool increased to 2500 mails

Mail pool is increased from 1104 to 2500 mails. (Nvram state is changed)

BZ 148Incoming Call from SIP with different ringing tone

Added new nvram flag ".ex_profile.flags.trunk_alt_priv_ring". When set to "1" all calls from SIP trunks will use "UK style ringing tone".

Avoid signalling fault from analogue sub stations

From substations a short press on ID + M can be signalled as ID. When the global flag: "ID_and_IDM_to_IDC_CRM" is set, wait for 300 ms before ID is accepted.

BZ 147 Muted busy tone removed from SIP trunks

SIP stations/trunks does not get the muted busy tone (Same behaviour as PNCI system)

Start of ATLB-ATLB conversation no need for duplex resources

When starting a call between two local ATLB stations no duplex resources are allocated.
When incoming call from SIP to ATLB no duplex resources are allocated.
This will give the possibility for setting up calls in system with only ATLB12 cards.

  • SIP node or "collect N digits" programmed allow extra digit being programmed, accept with M-key.
  • Destination node AlphaCom behave as AMC 8-9.





Known Issues (Latest release)


Known Issues

Issue 3020: Missing “Exch. Missing” text:

When making a global group call and some exchanges do not receive the group call due to not available audio links, there should be a display message "Exchange Missing".

Issue 3124: AlphaNet - NAT

AlphaNet does not work if NAT traverse is used.

Log System (Syslog)


The logging is handled by the syslog-ng log daemon. This can be configured to route the logs to different media. The log can be stored on on-board flash, or sent over the network with different protocols.

Known Issues

Large log files on on-board FLASH

The log is stored on a limited sized Flash partition by a file system. Routines to handle larger log amounts, like automatic clean up of older files have been implemented, but we still experience problems if the log rates get to large. These problems occur before a theoretical log rate versus free space analysis, mainly because of file system issues with a small number of available flash sectors. This file system factor makes it difficult to make an accurate estimate of handled log rates so the following is based on experience:

Limits: 

Log rates lesser than 1440 events a day (an average of one each minute) should be handled with no problem.
Log rates of 17280 events a day (one each 5th second) is experienced to give problems.

Guideline: 

If you are above 1440 events a day you should evaluate to use the Remote Syslog option, and turn off the Local Filesystem Log.
If you are closer to the 17280 events log rate we strongly advise to use only the Remote Syslog option. 
If your system are logging above the 1440 events a day to the filesystem you should regularly monitor the logs.

Note: 

From AlphaCom 10.23 a log limiter on the System and Debug log is implemented, allowing for a maximum of 60 events a hour. 
If this limit  is reached, it will be notified by a log message. Because of this limit the above guidline will only apply 
to the Statistics log.

Known problems AMC hardware 8000/4

None as of now

Known problems AMC hardware 8000/2

Issue 2747: RCI not supported on ACE7:

RCI not supported on ACE7. The RCI signals on P1-c19 and P1-c22 are terminated in test points on AMC-IP.

Issue 2741: Redundancy control from APC:

The redundancy control system from APC is not working (software and hardware).

Issue 2787: AMC serial port: No RX, no data on TX:

It turns out that the RS232-drivers on the AMC-IP-board have an automatic shutdown when it detects missing received data (illegal voltage levels). This will be fixed in future hardware version, but it can be fixed on current hardware by a minor modification. Remove R698 and R695. The pins must be connected to Vcc (3,3V).

Issue 2806: “Temperature Alarm" in ACE.7:

This problem is probably related to the fact that the AMC-IP board never had a connection to the over-temp. signal from the ACE7 backplane. This is related to the problems with RCIs from the same backplane.

AMC Filter board

Issue 2723: RS422/RS485 Signal Pinning:

The pin out for RS422 signals on the filter print for E20 and E26 differs from the pin out on the E7. The Rx+ is switched with the Rx- and the Tx+ is switched with the Tx-. The only consequence is that the same cable can't be used on E7 and the E20-series. From filter print version 3 (DB8001/3) the mapping is correct.
