this is the code that breaks outgoing calls on grandstream
...d working.
Any help on why it breaks? Any possible fix?

T38 and codecs negotiation
...xxx RTP/AVP 96
a=rtpmap:96 telephone-event/8000
a=fmtp:96 0-15
a=silenceSupp:off - - - -
a=sendrecv
if in the originating INVITE there was the a line for telephone-event
mapping.
Looking chan_sip.c I understood that the problem is related to t38
capabilities and in particular at row 5636:
if (!newjointcapability) {
/* If T.38 was not negotiated either, totally bail out... */
if (!p->t38.jointcapability || !udptlportno) {
ast_log(LOG_NOTICE, "No compatible codecs, not accepting
this offer!\n");
/* Do NOT Change current setting */...

Possible fix for grandstream outgoing

No subject
non-video mode, it is never able to add video to the channel? Is this
correct, or am I missing something?
It looks as if the codec 'jointcapability' is calculated at the start
of the call, and can never be added to (with exceptions for T.38 fax)
as any SDP update is masked using the existing 'jointcapability' and
knocks out the newly requested codec.
Is that right?
Thanks,
Steve
