Errors Corrected

SIP: Support of Early Media "183" (MTN 1371)

Incoming Calls from SIP to AlphaCom did not allow Early Media.

Camp on Busy (MTN-1373)

In some camp on busy situations a system reset could occur.

Silence Call not Working (MTN-1390, MTN-1395)

The 11.5 data commands and parameters for silence call setup using $CALL and $SC are now included in the 12.3. software.

Issues with two Simultaneous ReCall Features (MTN-1359)

Reset could occur if dispatching two simultaneous ReCall playbacks to groups, where groups contains overlapping members and AlphaPro missing members configuration > 0.

BUFFER_TOO_SMALL SysLog Messages (MTN-1405)

When reporting absence status a "Buffer too small" debug SysLog message could occur. Previously fixed for the 11.3 software.

Avoid Tone Test and Scheduler During IPHA Standby Mode (MTN-1256)

Both the scheduler and the Tone test was running in an AlphaCom in standby mode.
This would generate syslog messages.
Now Tone test and Event Scheduler is stopped during standby mode.

SIP Station Timeout on Collect Digit Features (MTN-1410)

SIP stations dialing feature 81 / 83 configured with collection of digits would timeout before the digits where sendt to the SIP trunk.

Remove Directory Numbers from the 614 Menu (MTN-1389)

These numbers are removed in Autoload: 54, 55, 0, 627, 628, 8270, 8260-8266.

Ringing Group from SIP Trunk (MTN-1331)

It was not possible to use ringing group calls from SIP in combination with node flag "180 Ringing".

Busy Override to Ringing Group (MTN-1357)

It was not possible to do busy override of stations already in call from answering Ringing Group call.

  • If A is answering Ringing Group call from B.
  • C is not able to do busy override to A.

Call Forwarding (71/72) Fails for SIP Station (MTN-1361)

When a SIP user calls a station (ASLT or IP) which is forwarded, the call will not connect with the target station.

Dummy Stations as Default SX Speaker (MTN-1353)

Sometimes the audio was not connected correctly from a Dummy IP talker of a SX conference.

Wrong Default CRM Notification Tone (MTN-1327)

CRM notification tone is now default setting.

Avoid Overlapping Talkback UDP Ports for Mixer Station (MTN-1350)

Sometimes there could be conflicting use of UDP ports for talkback and multicast SX conference streaming when using the Mixer Station.
This would result in no talkback audio from the Mixer Station.

Send Private Info to IP Station when Using Feature 80 (MTN-1348)

Using the feature 80 to control station private setting did not update the display of the INCA stations.

Missing B subscriber info, Voice Recording in Ring-Master Installations (MTN-1349)

When answering call request from remote nodes, remote stations number and name was not updated in the active proxy stations list.
This resulted in missing info for Recording sessions and event handler using %dir/%nam.

Configuration not Synchronized in IPHA (MTN-1332)

In situations where the configuration slave has ex_data waiting to be written to flash, the synchronization of configuration data from config master will trigger writing to flash thus overwrite new configuration.
Now configuration slave will inhibit writing local changes to flash file.

Issues with Ringing Group using SIP Station Members (MTN-1340)

Simultaneous answer from two SIP stations of a ringing group call could in some situations resulting in Exchange reset.

Issues with Answering Ringing Group Call Early (MTN-1023)

If a ringing group call was answered before first ringing sequence is finished, the ringing will continue at the other receivers of the call.

AlphaCom Ignores "486 Busy Here" from Connected SIP Phones (MTN-1425)

The "Reject" key of the ITSV-1 SIP station would not cancel the incoming call.

Enhancement

Configuration of Common Codec for all Program/GroupCall/Conference (MTN-1374)

A common setting of codec for "one to many" call types can be configured in NVRAM.

.ex_profile.glob_const.CP_codec = 0 

Default 0 = G722. Codecs values are the same as for codec selection of the $VAC command. Using AlphaPro configuration of individual codecs for Group/SX will overrule the common setting.

Added Configuration for Changing SIP Reply Codes (MTN-1331)

For SIP trunk station calls, AlphaCom will default reply with code 480 in fault situation and 182 for early media.

.ex_profile.ip_config.SIP_REP_480 = 0 (0x0000)
.ex_profile.ip_config.SIP_REP_182 = 0 (0x0000)

Configuring other SIP codes can be done by changing the parameters to legal SIP codes. (0 = use default)

Feature for Mixer Station WorkChannel Talkback from DAK keys

New feature 120, used for WorkChannel talkback from Mixer station.

Support of TFIE-6 Display Update(MTN-1370)

The new TFIE-6 requires a special display protocol to operate.

If only one member of the age multicast bitmap, then send age message as tcp DIP (MTN-1399)

Optimization: using TCP to single stations avoiding multicast repetitions to groups of only one station.

Moved line volume from state to nvram (MTN-1401)

Turbine line output volume is now configurable from AlphaPro 11.6.3.12.

Support Event Handler DAK as RCI for function keys in CRM mode

The Navigation keys in CRM mode available on IP desktop/flush and DualDisplay are now reported to Event handler as DAK as RCI sub event 101->104.

Automatic Work Channel Implementation (MTN-1311)

Errors Corrected

Talkback Issue if Mixer Station Down During Multi Talkback (MTN-1384)

If the Mixer Station is reset/offline while active in multi conference talkback, the Mixer Station is not able to do talkback after re-registration.
Fixed with proper cleanup of talkback states during station down.

Issues with the Automatic Static/Dynamic Multicast Port Allocation System (MTN-1387)

For 12.3.3.1 software a backward compatibility algorithm was introduced to support older IP station software in systems without Mixer Stations.
In a Mixer Station system, if one or more SX-conferences was started before the first Mixer Station was registered, these first conferences would use static multicast UDP ports, inhibiting correct SX-conference mixing. Fixed by checking all configured stations, not only registered station.

There is also corrected an issue related to overlapping use of Multicast UDP port and Mixer Station talkback UDP port, inhibiting talkback from Mixer Station for some combinations of SX mixing.

Restarting of Terminated Recording Sessions (MTN-1316)

In a system running with recording of 24/7 SX-conferences, the recording sessions would not be restarted in case of network issues or Recorder PC reset.
AlphaCom will now monitor and restart faulty recording session.

RE-INVITE During Recording Sessions Leak Memory. (MTN-1317)

The Recorder PC uses RE-INVITE messages for monitoring of active recording sessions. Each RE-INVITE will allocate memory in SIPD.
Memory will be free when Recording session ends.
For system using 24/7 conference recording the session should ideal never end, thus result in overuse of memory over time. Fixed.

Error Corrected

Queuing for Group Call Gong (MTN-1229)

Multiple simultaneous startup of group calls with gong could make the group call function hang.

Issues with group call to slave module, and when SX conf Speaker is in slave module (MTN-1204)

Audio distribution was depending on an active link connection on both Eth ports, also unused/unconfigured Eth port had to be connected to a network switch.

Group Call with Max Missing Members (MTN-438)

Group call with configured max missing members > 0 did not start at all.

Restrictions of C-key as Station Private Mode Switch (MTN-1192)

The use of C-key-Private is now only allowed when privacy mode is set to "Station Controlled" in AlphaPro. That is the same behavior as analogue stations.
Now the C-key is not working for private mode setting if station is configured with "Always private/open"

Not Possible to Delete or Add Custom Scripts in AlphaWeb (MTN-1096)

There was a permission problem of the files after the security upgrade of AlphaSys 11.5

edo "\x00"


Memory leak in SIPD (AL-2658)

Memory leak in sipd found during Exigo testing. New SIPD 2.09.

Call Status Broadcast DP Messages Should Use Current User Directory Number (MTN-1069)

In some customer systems several users are configured for a single physical station.
Connected 3rd party equipment then needs information of user currently called.
The call status messages CALL_STATUS_BC, CONN_STATUS_BC and DISCON_STATUS_BC was using the default user directory number for the B-station of the call, now the current user is used.
For backward compatibility flag ".ex_profile.flags.AMC10_bc = 1 " revert to default user.

Incorrect OPC Handling for Incoming SIP Trunk Call to Ringing Group (MTN-847)

The original Q_ELEM_ADDED message contained the physical number of the SIP trunk proxy as mail sender.
Now the message contains the directory number of the SIP caller thus making it possible for OPC to show some readable information.

Avoid temprature alarm in XE1 (MTN-498)

Temprature alarm will no longer be generated in the XE1 exchange.

Avoid Overlapping ATLB12 and IP Station Physical Numbers (MTN-610)

IP stations will have priority above ATLB12 station if configured on same physical number.
Same functionality as for ASLT. Need reset to take effect.

CRM Backlight Update (MTN-654)

CRM backlight will now be turned on after restart.

Issues with Event and SysLog Reporting of Global SX Speaker (MTN-1065)

Speaker of global SX conferences was not reported correctly to SysLog. The $ST_STATE message now contain the active conference of the station.

Enhancement SIP

Class Of Service Configuration for Each SIP Trunk

It is now possible to configure COS for each SIP trunk.

 .module_profile.node_profile[1].class_serv 

If set to 0, default COS will be used (15 - Outside Telephones).

SIP as members of Conference and Group Calls

  • SIP stations and SIP trunk stations can be included in the group call groups.
  • SIP stations can be set as default member and speaker of a SX conference.
Limitation: SIP stations can not dial them self into conferences by dialing 8201. 
            SIP stations can only be included using $DP messages or features codes for conference to group/station.
            SIP stations can not signal M-key to talk. Must use $CONF_TALK. 
            All members of the group call or SX conference must support the same Codec.
  • New flag for Allowing SIP Stations as Members of Group Call and Default Speaker of SX Conference
Flag is default false for backward compatibility. Available in latest AlphaPro 11.6.
&000260 .ex_profile.flags.cp_allow_sip = 1 (0x00000001)

SIP Parsing "P-Asserted-Identity" in the 200 OK header (MTN-1182)

If a "P-Asserted-Identity" is found in the reply for an outgoing INVITE, the new user name and/or display name are updated in AlphaCom.

Option for Silence RTP Audio to SIP Stations

When SIP stations are used as default speakers in conference rtp audio can be sent back to the SIP station to avoid timeout on SIP side due to missing RTP audio.

52 &000256 .ex_profile.flags.cp_bp_silence = 1 (0x00000001) 

Node: This flag is intended for "IP only systems". If this flag is used for a system with ASLT/Multimodule there will be no audio distributed to analog stations.


Enhancement Mixer Station

Enhanced Turbine Mix Station Support

Turbine Mixer stations was first introduced in the limited X-version software 11.2.3.12x.
Feature Description: Multi Conference

Multi Talkback on M-key

The mixer station has default talkback to all active conferences in the mix when pressing M-key from idle.

The functionality can be turned off using the station flag 3: NO_MULTI_TALKBACK

The new feature 119, multi talkback can be used for DAK key activation.

Automatic DAK LED update of Mix Controller Station

Based on param3 of the Conference Feature 65, the LEDs of the DAK keys for toggling conferences in the Mixer can be auto updated without use of event handler.

Feature 116 "Volume and Control Mixer Station"

Conference Mixer Station Feature 116 added to COS 1.
Auto-loaded directory numbers:

8260-8265 used for individual channel, line and mixer volume control
8266 Toggle conference

Feature 119 "Multi Talkback"

Multi Talkback Feature 119 added to COS 1
Auto-loaded directory number:

8270 Multi talkback

Enhancement

Backward Compatible Multicast Group Call

Previous X-versions of 12.3 used dynamic allocation of udp ports for multicast group call. This is required for the new Mixer Station software.
Not all IP station software versions did support dynamic udp port usages thus audio was missing during group functions.
Now the Multicast system of 11.5 and earlier versions are used as long as no Mixer Stations are configured in the system.

Enhanced TST commands

cnf - list all active conferences and its members.
res - Now show IP resources currently in use. (CC 01 Count:32, Type:(01) PCMC, Used: 3)

Direct IP Audio Enhancements in "One to Many" Calls

For previous versions of AlphaSys audio in SX conferences, Group Call and Program used the AlphaCom backplane for audio distribution.
Use of the backplane require audio trans-coding, the result is additional audio delay, distortion and limitation of the frequency response.
Optimizations done:

  • Program, Group Call and SX conference with IP audio source, will distribute the received audio source to IP listeners without re-coding the audio.
  • Global SX conference and global group call will connect other nodes as IP audio into the group call or conference. Resulting in less delay and audio IP-resource usage.

Audio is still copied to the back plane for inclusion of ASLT/AGA types of stations in calls.
No optimization is done when MultiModule is used.

Codec use in Global Conference and Group Call (MTN-1148)

Global SX conference and Group Call only supported G722, now the setup is based on the SX/VP Codec configuration of the Initiator node

Increased DAK string length from 19 to 25 bytes (MTN-1050)

The length of the DAK string is increased from 19 to 25 bytes.

Store $VAC Config in Flash

VOIP parameters for the IP dummy station using the $VAC command is now permanently stored, thus will survive system reset.

Key Press and Release Option on $DIAL_DAK

It is now an optional parameter to specify DAK press or release of the $DIAL_DAK message. Default is press/release as the original $DIAL_DAK message.

Support of 10 OPC Servers

Support of a total of 10 OPC servers in AlphaNet. Limited to two servers connected to each node.

Configuration of Syslog info (MNT-676)

Added configuration of: SysLocation, SysContact and SysName setting. Configuration found under AlphaWeb->Configuration->Logging->SysLog Info.

Feature 118 "Station as Program Source"

New feature enabling an IP station to dial a feature code to become audio source of a program. Will only work if the program is without existing program source.
