Thanks Andreas for your answers. I do have the code for checking return code from PJSUA APIs but I didn't mentioned here for brevity. Every PJSUA API in this sample code was successful. When I checked the WAV file, using file command then following is the output: 1372888804:09:2012_12:01:48.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz While I try to play this file using play command on linux, it gives following output and the file is not played: -------------------------------------------> root at ubuntu:~ # play 1372888804:09:2012_12:01:48.wav 1372888804:09:2012_12:01:48.wav: File Size: 995k Encoding: Signed PCM Channels: 1 @ 16-bit Samplerate: 8000Hz Replaygain: off Duration: unknown In:0.00% 00:00:00.00 [00:00:00.00] Out:0 [ | ] Clip:0 -----------------------------------> The duration of the file is shown is unknown, But when I try to play a file which is successfully being played it has the following output: File Size: 86.6k Bit Rate: 128k Encoding: Signed PCM Channels: 1 @ 16-bit Samplerate: 8000Hz Replaygain: off Duration: 00:00:05.41 Here duration of file is known. I think that whenever the recording is over, I need to destroy the recoder using pjsua_recorder_destroy but don't know when should I call this. Should I call this just after calling pjsua_conf_connect????

However, this can easily be done manually (you just need a little bit knowledge about file handling and the WAV file format). Regards, Andreas -- Dipl.-Ing.
