Just in case anyone still has this problem; close & reopen the sound devices using PJSUA API method pjsua_set_snd_dev(). PJSIP recaptures the microphone with this method although this operation is consuming ~500ms on my WM6 device which adds to the setup delay of VoIP call. Is there any more efficient way to recapture the sound device and that too just the microphone (above API method recaptures both mic and speaker)?

Yesterday I tested on an O2 Exec. On this PDA there is no problem. In fact if I start a SIP call and then the PDA receives a GSM call, during the GSM call, the mic on the PDA goes to both the GSM and SIP calls. The speaker on the PDA only comes from the GSM call. Then after the GSM call ends, the mic and speaker are again connected to the SIP call. Another strange thing I noticed in this test, sound from the telephone (the GSM call) went to the speaker on the PDA, as expected. But it also went to the speaker on the other end of the SIP call. Going back to the HTC, I was not able to reproduce Girish's results. As soon as a GSM call is answered (or initiated) the PDA's mic is no longer available to PJSIP. Subsequent GSM calls did not restore the mic for me. The only way I can restore the mic on the HTC is to terminate and restart my program.

And for possibility #2, I also couldn't find such topic in m*dn forum :( Btw, thanks for reporting the bug, it has been fixed in r2366.
