I'm solved my problem and i want share with you my solution.
send rfc2833 dtmf() use the the function rtp_session_send_with_ts() for sending rtp packet.
One thread is used for send rfc2833 dtmf() and nother one for rtp_session_send_with_ts() for audio traffic.
unfortunately rtp_session_send_with_ts() is not thread safe and this cause the stop of sending rtp audio traffic.
A critical section is solution.
thank's a lot
best regards

Hi,
i'm using ortp stack and it works fine when data is audio PCM.
When i try to send dtmf rfc2833 with function
*rtp_session_send_dtmf(..)*the stack is blocked and no more rtp packet
are sent.
*rtp_session_send_dtmf (..) *is blocking???
this is snip of code
...............................
...............................
rtp_session_set_scheduling_mode(session, 1); // BLOCKING MODE
rtp_session_set_blocking_mode(session, 1);
rtp_session_enable_adaptive_jitter_compensation(session, TRUE);
...............................
...............................
nRet = rtp_session_send_dtmf(rsession, (char)nDTMF, user_ts_snd);
user_ts_snd += 480;
..................................
If no send dtmf rfc 2833 nothing is blocked and audio flow is regularly
sent?
Can anyone help me?
anyone have the same problem ?
thank's in advance for your help.
best regards.
