Detecting DTMF

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
