Hi again.
On my previous discussion on this list, i learned that RTP/AVP with a a=crypto attribute means optional SRTP.
I suppose FS supports optional SRTP, but when i look at the sofia code, afaiu fs does not support it.
Right ?
A code snippet from sofia_glue.c
if (m->m_proto != sdp_proto_srtp) {
switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(session), SWITCH_LOG_ERROR, "a=crypto in RTP/AVP, refer to rfc3711\n");
match = 0;
goto done;
}
