Software in production: AMC 11.2.3.10<br\> Note: For each software version the NVRAM version is listed. If the NVRAM version is different, the AlphaCom InterCom configuration will get default configuration, and then you must do a SendAll from AlphaPro to restore the configuration.<br\> All AlphaWeb configuration will be kept.<br\><br\>

AMC 11.5.3.1

Release: Official, available on request
NVRAM version 11.02.03.11
Data: 4th of Desember 2015

This software only runs on AMC 11 hardware and require use of STIC
This software require BSP 31.0.3.x or higher
The amcd (main InterCom feature software) origin from the 11.2.3.11 and the Web from 11.3. Release note is based on amcd changes since 11.2.3.11.

System upgrade file:<br\> alpha-sys-11.5.3.1.apkg

Error Corrected

Missing Conversation LED outgoing conversation (MTN-734)

Outgoing AlphaNet Conversation to IP-only node, from Analog station with handset lifted resulted in missing microphone led and audio.

Faulty SysLog Statistics During Inquiry Operation (MTN-745)

There was a faulty "re-open" conversation log during inquiry.

Tight Timing in HAIP Could Cause Unintentional HA Reset

Internal Watchdog update could timeout during high load situation causing the HA system to reset.


SIP Transit Issues (MTN-718, MTN-709)

In a transit SIP call the initiator station will freeze if the remote SIP trunk replies with a 4xx message.
Pressing M or DAK on analog station after dialing prefix to SIP node make station hang.

Multicast Audio Flowire Issue

AlphaCom multicast audio setup and cancel messages are now repeated more often due to possible UDP collisions when multicast used on Flowire.

Ringing Volume Setting Not Used When Receiving Ringing Group Call (MTN-681, MTN-536)

Now allow use of AlphaPro configured ringing volume when receiving ringing group call.

Use of DAK keys programmed with "DAK as RCI" during conference (MTN-698)

When using DAK keys during conference the conference audio was disconnected during DAK key execution.
Now DAK as RCI activation from DAK keys without DAK string will be handled without audio issues.

Issues with Turbine Stations Receiving its Own Audio when Talking into SX Conference

When IP stations speaking into SX conference now the IP station is removed from the list of "listener" stations.
(INCA avoid turning on the loudspeaker when speaker of SX conference)

M100. Country Specific Characters Disabled Directory Numbers (MTN-670)

Using German characters inhibited exporting the directory number to the M100d configuration. Fixed

Issue with Recording of Outgoing Conversation to IP Only nodes (MTN-689)

For recording of outgoing ASLT conversation to an "IP only node" there was no audio sent to the recorder.
The system could also reset when M-key was used during recording in the same situation.

New Parameters for Event Handler Function AMS and AMG did Not Work Correctly (MTN-724, MTN-725)

The implementation of configurable "handset volume override" on AMS and AMG introduced with on version 11.2.3.10 did not work correctly.

Choppy Audio in SX Conference (MTN-729)

Long time use of SX conference in combination with Turbine Extended, generated issues with the sound quality.

Applying filters on AMC-IP gives user cryptic fault message (MTN-728)

Improved fault message

Event 5 is not Triggered for IP Stations (MTN-718)

Event 5 MIC use is now working in IP-IP conversation.

Problems with UK Style Ringing Tone from SIP (MTN-623)

Mismatch in flag setting between AlphaCom and AlphaPro.

SIP Trunk Fault Message (MTN-751)

When a SIP trunk call was terminated from AlphaCom side, the following unnecessary error message was logged. 

E SIP  Not able to process SIP OK on BYE 2xx response, call is NULL

Same IP sub-net on Eth 0 and Eth 1 causes Issues (MTN-777)

AlphaWeb now inhibit overlapping sub-net range on Eth 0 and 1.

Enhancements

Pin Code on ODC featrue (MTN-783)

Pin code is added by setting a 4 digit number to parameter 2 of the 88-ODC feature.
Users entering the ODC must dial the 4 digit number to enter the conference.

Snatching of IP Resources (MTN-652)

When activating some features with alarm priority and no more IP resources available, the system will now release resources from other lower priority activity.
Features with snatching available:

  • Group Call with alarm priority
  • AMS / AMG with handset volume override (HVO).

All features using IP resources can be the target for snatching by a high priority feature (disconnected)

  • Program
  • Group Call
  • Conference
  • Message Playback
  • Conversations
  • AlphaNet Calls
  • MultiModule
  • ODC
  • Recording

Silence Call Request Mode (MTN-693)

Add silence call req mode option. 

op_constants(0)!CRM_tone = 4 -> No Call request mode audio in initiating station.

UTF8 Coding of Event Handler "log" to syslog

The event handler log "text" function is now converted to UTF8 coding before sent to SysLog.

Recording On Demand

The $REC function from AlphaSys 11.3 is now supported on 11.2. Issues discovered when using $REC multiple time in one session is fixed (MTN-719).

SIP Trunk Monitoring (MTN-240)

SIP trunk monitoring can be enabled from node flag. Monitor SIP trunk nodes with OPTION - OK signaling, report UP/DOWN as AlphaNet links. Enable monitoring individual for each SIP trunk node. Setting bit 7 (count from 0) 

.module_profile.node_profile[2].flags = 128 (0x0080)

Support of IP Dummy Stations in SX Conference

The AlphaSys 11.3 support of IP dummy stations in SX conference in now available.

Support Forcing Codec of SX Conference

ex_profile.prog_conf_profiles[1].flags
Bit 1 = Recording (default on)
Bit 3 = G711a (Telecom level)
Bit 4 = G711u (Telecom level)

If not bit 3 or 5 set, G722 will be used. (Supported in AlphaPro 11.6.3.9)

Added Counters for Event Handler String Usage

For debugging purposes the tst command "evh list all" will print all event strings and show number of times used as last parameter (x). Counters are reset after each time the Event list is printed.
Useful for discovering looping event triggers.

Allow Digit SIP Trunk Signaling for Incoming Call From SIP trunk (MTN-453)

Activated with use of $TRUNK_SIG <station>. 

Example from Event Handler: Owner Station w UDP - 8. Event Type : "7-Conversation incoming". Change "On" . Relate to " Station w UDP" , node "sip node", id "1".
$TRUNK_SIG %1.ref

Allow AlphaPro use When Linux Serial Console Active (MTN-740)

AlphaPro on IP can now still be used when serial console is activated.
