There are few articles in PJSIP FAQ which describes about implementing media ports, please see http://www.pjsip.org/trac/wiki/FAQ Once you've implemented the tone detection media port, you can register it to the conference bridge and connect it to the call to start listening for the tone. I prefer this solution since it doesn't need any modification to stream.c. RFC 2833 digit was implemented differently since it needs to work on the RTP packet level rather than PCM level, thus it needs to reside in stream.c. cheers, -benny > > Looking forward for quick response. > > Thanks & Regards, > > Ravi Inder Singh > > > > > > > ------------------------------------------------------------------------ > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip at lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org -- Benny Prijono http://www.pjsip.org
