[Freeswitch-users] record_session - dtmf and silence

I have a lua script creates a session and do a lot of stuff… And I record this session using the record_session api command… The problem is, sometimes I have session:execute(‘send_dtmf’,’1234@250’)… And in the log, I can see that too, but not at the session wav file. Is it possible to have this dtmf’s at the wav file? The second problem is, sometimes I have a big silence, like 10 seconds of no sound, and at the session wav file I don’t have this silence interval, but it’s important to me… Could I have this silence at the session wav too? Thank you, Leonardo Ribeiro
