T38 and codecs negotiation
...xxxxx 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 */...
