I wanted to add one more piece.... I decided one more test, using headset, and during the call chose (RECORD) the conversation. It was certain on playback that the audio in both directions was captured, but the local talk (OUTBOUND) was not being passed along. Also, I did not hear any DTMF captured and not sure if IN-BOUND or what RFC is supported for DTMF.
I really believe if these few things are nailed this could be the SIP app of all for the PPC platform - the call setup and voice coming in seems FANTASTIC. And I have tested about every app for the Windows Mobile platform .... Also - the app does not weigh the device down, and is still very usable.
I hope we can work this one out.... I have 2 trouble tickets into support on this one.
