Yes, the pjsua-lib detected a dtmf but the callee never has pressed that digit. It's randomly, sometimes function ok and sometimes not. Perhaps is the codec that I'm using. I'm using PCMU/8000 codec. Please help me.

I've a problem with dtfm detection. I developed an application using pjsua-lib, my application makes a call and plays a prompt, during the playing it can receive a dtmf and repeat that message. My problem is that I receive a dtmf but it never had been dialed. My log is the following: 11:53:01.333 strm0x9089de4 Received DTMF digit 9, vol=11 What does the trace look like, when there is an key really pressed?
