AlphaCom 11.xx Release Notes

<br\>

AMC 11.1.3.0(2010-07-15)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 11.00.

System upgrade file:<br\> alpha_sys-11.1.3.0.apkg<br\> Running this software on an AMC 11 hardware require use of STIC

Errors Corrected

BZ 356 Global Messaging and Recall

Remote dialing into a local ReCall group call did not turn on microphone on initiator station (no sound). Message to global group with the option set for return to standard group call after message end resulted in local feedback of group call audio in initiator station.

BZ 357 Feature Reminder IP station

The feature reminder blink sequence was not equal with analogue stations.

BZ 360 BZ 341 Event Handler IF statement

The event handler IF statement only evaluate numeric values thus IF statement on text evaluate faulty. A %strlen() operator added for evaluation if text string is empty.

BZ 395 Low volume when IP station initiate ReCall

Loudspeaking IP stations was using echo canceler during recording of ReCall message thus variable volume.

Transit call to SIP

Calling via transit node to SIP would reset private ringing after 6 second if not SIP OK received from SIP.

New Ring Master Daemon allows more than 6 simultaneous calls

The Ring Master integration Daemon could do an reset if more than 6 simultaneous calls was activated between AlphaCom and Ring Master.

Camp On busy when calling busy Ring Master station

When calling a busy Ring Master station from AlphaCom the AlphaCom will now give camp on busy. Works also for transit calls between two Ring Master system via AlphaCom.

BZ 405 and BZ 407

(These bugs was introduced on X version 11.0.9.4 thus never been released.)
SIP client call causes IP stations to loose connection. Missing audio on AlphaNet Call from IP Station to Analogue station


Enhancements

STIC Stentofon Identity Card

AMC running on AMC 11 hardware now supports the STIC.
Stored on STIC:

  • Basic IP configuration
    • Eth0 and Eth1 IP addresses and mask
    • Default gateway
    • Filter setting for AlphaWeb and AlphaPro
  • Node number
  • License string

InterCom configuration and other AlphaWeb configiraton must be restored with the use of the AlphaWeb Backup system.

SoftClient License

SoftClients now require use of a special SoftClient License. License string is increased from 24 to 36 bytes if SoftClient license is include. System still compatible with the 24 bytes license.

Billing PTR trunk

Trunk busy reported to Billing system, Billing can activate alternative trunk. Trunk "break out code" configurable in the AlphaCom database.

Volume override related $DP messages

Added new DP commands related to Volume Override. 

$CAS Cancel all active calls
$MVO Mask volume override

AMC 11.0.3.1(2010-05-03)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 11.00.

System upgrade file:<br\> alpha_sys-11.0.3.1.apkg<br\>

Errors Corrected

Priority of playback of voice messages

The priority of playback of defined message: 1. Recorded message from station, 2. Uploaded message from AlphaWeb, 3. ASVP message.

Priority of IP station audio playback

When more than 1 audio source available: <br\> 1. Group Call, 2. Program/conf distribution , 3. Conversation

Missing audio in IP multi module

Conversation from IP stations/SIP stations to a slave module stations could have corrupted audio if the IP/SIP stations had previously been used in a trans coded IP conversation.

Voice Messaging "Meet Mee"

The meet me(99) system for messaging is changed to inhibit use of 99 for ReCall and SVP messages from start. If control bit 2 (MeetMe) are enabled 99 is activated from gong (or gong check if no gong). This will reject all 99 during ReCall recording and for 99 during messaging function with MeetMe not enabled.

AMC 11.0.3.0(2010-04-22)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 11.00.

System upgrade file:<br\> AMC card version 1-4 must be image upgraded with axeu_b2200_a_1100300.aimg <br\> AMC card version 5 must have image axeu_b3000_a_1100300.aimg

Errors Corrected

BZ 333 Busy override not working from ATLB stations

Allow override features to be dialed from ATLB stations during private ringing or busy tone without use of R-key.

BZ 340 ODC to group failed

Setting up ODC to a group failed, only some of the participants where added.

BZ 275Display text from $SM RingingGroup to SIP Phones

Display text sent to SIP stations was only the sending station display text. Now custom text in the $SM command is used.

BZ 353 Incoming SIP INVITE with audio and video in SDP fails

SIPD fails to parse a Audio offer when the audio offer is followed by a video offer.

Enhancement

Integrated Support of Messaging features

Integrated ASVP support

The voice system from ASVP card can now be installed as a software package on system with the AMC XE hardware.<br\> Require enhanced messaging license.

ReCall, Delayed Group Playback

A system of delayed playback of group call is now available on both AMC new and old AMC IP hardware. <br\> Require basic messaging license.

AutoAttendant

A voice menu system can be configured as a feature in AlphaCom. AMC XE hardware only. <br\> Require basic messaging license.

Message Playback

Custom stored messages can be played back to local or global groups. Messages is uploaded from AlphaWeb. AMC XE hardware only. Require basic messaging license.

New Backup System

A more complete system backup is available from AlphaWeb.

New Event Handler features

New LOOP/ENDLOOP/BREAK function in event handler <br\> New %GES Group Exclusion station macro in event handler. <br\>

Audio UDP port test

UDP ports used for IP audio is tested in idle to discover "spamming" from faulty equipment.

AlphaWeb Station Configuration

Basic setting for stations can now be configured from AlphaWeb. <br\> Currently supported for stations in AlphaWeb: <br\>

  • Directory number
  • Display Name
  • Volume
  • Noice reduction level for IP stations.


Avoid attention tone when automatic seach on busy is activated

ex_profile.flags.no_att_tone_search = 0

Change tone on call requester mode

ex_profile.glob_const.CRM_tone = 0 
0 = Private ringing
1 = Lo pri feature reminder bleep
2 = Hi pri feature reminder bleep

Adjustable delay before ID signalling is accepted from substation

ex_profile.timeouts.ID_C_delay = 3 (in 100ms interval)

Stentofon IP station easy configuration

The IP stations can now be configured with an open MAC address from AlphaPro (11). This means that the IP stations will do registration only with their directory number. <br\> The IP station menu and WEB are updated with entries for adding wanted directory number. Only IP stations off line in AlphaCom will be allowed to register by directory number. <br\> This will ease replacement of stations without involving AlphaPro.

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.

Hardware Versions

<br\>

AMC hardware versions

Known problems AMC hardware 8000/4

None as of now<br\><br\>

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. <br\>

Issue 2741: Redundancy control from APC:

The redundancy control system from APC is not working (software and hardware).<br\>

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). <br\>

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.<br\>
