Hi Henning!

Thanks for the howto. How do you control the length of the DTMF tone? Do you have to send multiple RTP packets to get the respective duration or is ortp taking care of that?

The DTMF feature works fine for me:

1. Before calling rtp_session_new I call
     rtp_profile_set_payload(&av_profile, xxx,
&payload_type_telephone_event);  /* xxx: typically 101 */

2. After calling rtp_session_new I call

3. In order to send out a DTMF digit I call
     Following that I increment the timestamp.

Betreff: [Linphone-developers] ortp for DTMF only


I want to use ortp the send DTMF only - just send a certain code via DTMF.
I read the doxygen API but I am a bit confused - is there somewhere a
simple example of ortp usage available?
