> Ported to Asterisk SVN trunk (r373402 for the moment of writing).
> Support for using PTLib/H323Plus was added. Using PWLib and OpenH323 is no longer supported cause these projects are dead for at least 5 years.
> T.38 support based on this patch (ASTERISK-17180) was added.
> Interoperability with Avaya Communication Manager was improved:
> 1. ACM, when set to use DTMF over IP: rtp-payload, doesn't include receiveRTPAudioTelephonyEventCapability in it's TCS. If chan_h323 detects ACM on the other side it will try to use DTMF transport as set in dtmfmode config option.
> 2. When H.245 channel must be openned via separate TCP connection ACM reports h245Address too early (before it is ready to accept incoming TCP connection). If remote endpoint is Avaya Communication Manager, delay opening H.245 channel (processing h245Address) for 1 second.
> Processing of progress_setup and progress_alert configuration options was corrected. ITU-T recommendation Q.931 05/98 specifies 6 different values for Progress Description (1,2,3,4,5,8) though previous code allowed to use only 3 of them (1,3 and 8).
