Detecting DTMF

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

 

I am using pjsua on windows. I can hear the DTMF sounds when I stream the incoming audio on my speakers, but the callback on_dtmf_digit is not called. Wireshark says the protocol is G.711 PCMA.

 

Do I need to read and decode manually the incoming signal to detect DTMF ?

Am I missing a parameter somewhere ?

Or does something already exist for that ?

 

Thanks,

Nicolas
