Hi Varun, Were you able to get one-way voice while testing on emulator? The problem is that when testing with emulator on both the ends, there is no voice not even one-way. If one-end is emulator and other is X-lite, then one-way voice is there only from xlite to emulator. As recording is failing (Error in MaiscRecordComplete(): error code -14), voice spoken at emulator end is not getting recorded. What could be the reason for that?

The emulator has the half duplex issue. For these reasons i had told you can better use some real device for testing. I am sure that this issue will not come on the device. Also take a guess your logs and half duplex issue are also interrelated. see symb_mda_dev.c is nothing but the implementation if Audio device API and the log error specifies that it has some problem in recording the input/output media stream and also sue to which there is buffer overrun. hence the voice is half duplex. also #define PJMEDIA_AUDIO_DEV_HAS_SYMB_MDA PJ_SYMBIAN This setting controls whether Symbian audio (using built-in multimedia framework) support should be included. This enables the built in symbian audio support on emulator which may have issues in implementaion in emulator thyself. So from the above discusion you can conclude tha either ignore this issue and can continue for further development and if it is critical to be resolved first as per development strategy then you may use the device some how and test. and the last but not the least wait for some wizard of symbian to put some comments on it.

The information I got from various forums is that half-duplex works on emulator so atleast one party should be able to hear. I have also tried a call between Xlite and emulator. In that case, I am able to hear the person speaking from Xlite but xlite person is not able to hear anything. Also in the logs I m getting a message: symb_mda_dev.c Error in MaiscRecordComplete(): error code -14 and lots of 'Master/sound Underflow, buf_cnt=0, will generate 1 frame' messages. Your help will be really appreciated.

If you are using the emulator then please test it on the real device because the emulator has been reported some incapabilties regarding some capabilities. Also specify the SDK you are using. I can really help you in this because I have already developed a Softphone for Symbian OS successfully.
