[asterisk-dev] DTMF SSRC issue regression, constantssrc

[Daniel Pocock]

Hi,

I've recently observed an Asterisk 11.5 setup sending rfc2833 DTMF with
an SSRC that is distinct from the audio stream SSRC.

It was discussed in this bug which is marked "FIXED", but it is still
happening, maybe it is a regression now:

https://issues.asterisk.org/jira/browse/ASTERISK-16851

Has this changed again because of the PjSIP changes?

Is the constantssrc option to be supported going forward?

In case it is relevant:
- I'm using SIP
- the DTMF comes in to Asterisk using SIP INFO over TCP

This is a real road-block for any project where Asterisk has to work
with an existing system (e.g. some large corporate PBXes) and restricts
the choice of carriers for some users.

Regards,

Daniel
