[Freeswitch-dev] Getting DTMF from channel [SOLVED]

[Paulo Rogério Panhoto]

The audio thread was lacking a call to switch_core_session_read_frame().
After I placed the call, DTMF worked OK.

    About the contribution process, I was asked to send a ssh public key
and a jira user name. I sent the required information and got no reply
since.

    Kind Regards

        -- Paulo
