Otherwise, when I make a sip call everything works perfectly. I have tried many SIP providers and many BT headset but this issue remain.
It 'possible that some of you do a test to see if the problem is only mine or if it is a S III bug?
I tried to make a skype call through my bt headset (NEXUS10) It works just fine, but when I try to make it with my S3 I have the same issue I dont hear the voice and the microphone was not working, I tried to make modifications to the sound files (root) but I didn't find what the problem was.. I'm using slimkat7 and former user of CM10.2 (
I tried also to make a call but instead of using the BT headset I used the little waterproof speakers (built in mic) and I could make it!! So I have three conclusions (actually they are questions if someone could help me too, I'm:
-You need an a2dp earpiece in order to make VoIP calls (as my speaker that worked)
-It can be the ROM or kernel (I've heard that)
-You need to modify de sound files (root) in order to "unlock" the feauture with the Samsung Galaxy s3.
None of above are actual solutions, I think they could be solutions so if someone could help to make it happen I would be very greatful!
