Hi Sandeep I had no problems with dtmf detection using spandsp. CPU utilization was a little higher (can't remember by how however). I could turn detection on or off as required but in some situations I needed detection throughout the entire call so I ended up using rfc2833 event since the carrier supported it.

Btw how good is the detection with spandsp?? > > On Mon, Sep 19, 2011 at 7:17 PM, Omar Hussein <omarh2812 at gmail.com> wrote: > Are the tones inband? If so the FAQ gives suggestion on how to detect them by creating a pjmedia_port. I used this method with spandsp library for the tone detection. > > > > On 16/09/2011, at 9:31 PM, Sandeep Karanth <sandeepk.kdp at gmail.com> wrote: > >> Hi all, >> Does PJMEDIA support detection of DTMF and other telephony tones mentioned in RFC 2833 if they are sent in "tone" payload format rather than the "event" type? >> >> Regards, >> Sandeep >> _______________________________________________ >> 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 > > _______________________________________________ > 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 > > > > > -- > Regards, > Sandeep Karanth > > _______________________________________________ > 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 -------------- next part -------------- An HTML attachment was scrubbed...
