Hi 1. If i want to dial an extension using symbian_ua_gui what I need to change(/add) in the code? 2. Is it possible to add some API to do this like CTelephony. please help me. Thanks Opu

Hi, There is PJSUA-LIB API pjsua_call_dial_dtmf() that uses RFC 2833 mechanism. Please read the doc, perhaps you can find it useful. Regards, nanang On Thu, Oct 23, 2008 at 9:20 PM, S. M.

I have a small server app that listens and sends DTMF digits. The null device [pjsua_set_null_snd_dev()] is very handy for this application since the machine is not equipped with a sound card. When I send DTMF digits using pjsua_call_dial_dtmf() I do not hear the DTMF digit on the receiving side. I have tested this on other machines with a sound card and it seems that if there is a regular sound device, the DTMF digit is heard, but after a call to pjsua_set_null_snd_dev() nothing is heard. Is there a way to send DTMF when using the null sound device? Best regards, Archie

Hi, I've just tried to send DTMF RFC 2833 from pjsua with null-audio to xlite and the xlite played the digits well. Any other info to reproduce the case? Have you tried with VAD disabled?

Null device was ok for me. Pls make sure remote side has included telephone-event at its SDP, otherwise pjsip wouldn't send out 2833. regards, Gang On Mon, Nov 10, 2008 at 2:41 AM, Archie Rosenblum <archie@bbsti.com> wrote: > > I have a small server app that listens and sends DTMF digits.

Thank you, Gang and Nanang, for taking the time to investigate my issue.
