"Could not get audio input for record source 7" : SipAudioCall.start() Android 2.3.3 on Samsung GT-I9001 (Samsung Galaxy S Plus) doesn't work

I'm trying to start sample VoIP application on my Samsung Galaxy S. In the emulator application works just like a charm but during test on the phone I get :

09-20 13:41:57.874: VERBOSE/AudioPolicyManager(114): getDeviceForStrategy() strategy 3, device 2
09-20 13:41:57.874: VERBOSE/AudioPolicyManager(114): setOutputDevice() output 1 device 0 delayMs 0

09-20 13:41:57.884: VERBOSE/AudioPolicyManager(114): releaseOutput() 

The result is that nothing is captured by the phone and no voice is played through the speaker.

Thank you for help.
