I was playing around with your package (very cool by the way) on windows
mobile.  Sound in calls seems to be working fine.  But if the mobile device
gets a cell call, after that, the mic doesn't work in pjsip.  Any ideas
what's wrong?

Is it possible to be notified when pjsip loses the mic?  What needs to be
done to get the mic back?

Steven

I really could use some help here - please !

After getting a cell call, I called pjsua_destroy() followed by
re-initializing it (pjsua_create, pjsua_init, pjsua_transport_create and
pjsua_start).  Even after all of that the microphone (sound from PDA to
other side of call) is not working.  But if I exit my program and restart my
program, then the mic is working again.

It seems that something in pjsip isn't correctly re-initialized, but what??

I found a bug in wmme_sound.c, but fixing the bug didn't fix the mic
problem.

In that file, in pjmedia_snd_init the code needs to zero dev_info before
calling WideCharToMultiByte to convert the device name.  What is happening
now is each time this method is called to init the sound device, the "-
Input" gets added to the name, making the name grow each time.

But this did not fix the mic problem.  To repeat the problem - after the pda
gets a cell call, pjsip no longer gets sound from the mic.  The only
solution I've found so far is to exit and restart my program, which of
course is not acceptable.

Hi,

I am also facing the same issue as reported by Steve. Some more observations from my side:-

1. The Sound device callbacks to stream (get_frame and put_frame) are still working after GSM call has been made although it seems that only silence is captured as the VAD drops all the frames and only minimal RTP (marker bit set) packets are sent to other party.
2. There is another strange observation. As Steve mentioned, once a GSM has been done and VoIP call is done thereafter, there is a just one-way voice flow from other party to windows mobile device. Now while this VoIP call is going on, initiate an incoming GSM call to this device. For the duration when the Device is ringing for incoming GSM call, the voice is getting correctly captured from the microphone and 2-way voice flow resumes (although ringing tone adds to captured voice).

Can anyone throw some light on what can be causing this problem in mic.

Regards
Girish

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)?

I had discovered this mic/GSM problem while testing on an AT&T 8252 (HTC).

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.

Hi,

Since pjsua_destroy() will 'completely' shutdown the sound device and
restarting pjsua still doesn't bring back the mic, so I guess the
problem root could be:

1. bug in the wmme implementation (incomplete steps in shutting down
   the sound device)
2. bug of the system or hardware
   After skimming the wmme implementation I couldn't find such 'missing
   step', could you? 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.

nanang
