Can't get the UA_EVENT_CALL_DTMF_START event

[hallerbachj]

Hi,

I have some trouble to get DTMF to work. In the onEvent function of the PhoneThread.cpp I have expected to get UA_EVENT_CALL_DTMF_START, if I press a button on the smartphone after establishing a call with qSip. But I cannot get the event. Can you please give me a hint, how to get the DTMF events properly? My goal is to call a smartphone with qSip and when the user accepts the call, a wave file is beeing played and the user can acknowledge the message by entering a predefined DTMF code. The playing of the wave file is working (had to implement a switch audio source function). If you are interested, I can share the code with you.
