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 When SX conf Speaker in slave module (MTN-1204)

Audio connection was dependent on the connectivity state of both Eth ports.

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

Sending NUL Character from EDO (MTN-502)

Using hex encoding the character 0 was not possible to send on the EDO port. (All other values was okay)

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.

Clear All DAK LEDs on Turbine (MTN-1074)

The Event Handler IND command for clearing all DAK leds now also work for Turbine ECPIR with DAK module extentions.

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 (8201). 
            SIP stations can only be included using $DP messages or features codes for conference to group/station.
            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.
&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: [1]

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"

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"

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.
