Hi - Is there a way to detect DTMF tones when the RTP packets are in the incoming stream ? Is there a way to write some custom module to check the RTP packet contents and take action based on DTMF tones ?

Thanks

Kanwar

Kanwar,

No, I don’t think there is any way to detect [DTMF tones](http://en.wikipedia.org/wiki/Dual-tone_multi-frequency_signaling) server-side.
