Hi folks

I am having some trouble with the sip_append_audio_sdp variable. If I set it like:

<action application="bridge" data="{sip_append_audio_sdp=a=fmtp:18 annexb=no}sofia/external/sip:x@example.com"/>

It seems to have absolutely no effect. I'm pretty sure I have seen it working in the past, so now I'm wondering what the prerequisites are for it to work (i.e. what am I doing wrong?!).

I am using G729 in pass-through mode and have:

  inbound-late-negotiation [true]
  inbound-codec-negotiation [generous]

The expected behaviour is for the value of this variable to be appended to the local SDP on the B-leg. The actual behaviour is that nothing is appended.

Any thoughts?
