Hello, I am trying to test pjsua with a pc2pc call in a LAN environment. My environment is Ubuntu 10.04. After pressing "a" to accept the call at the remote end there is no sound heard at either ends and only a beep sound comes. It also asks to enter a numeric code in the range [100:699] and even after entering 100 there are no changes. After this, I tried to solve the problem as given in the manual. For checking whether it plays a WAV file using pjsua the following output is given without any actual sound heard: **************************************************************************** abhat002 at shetland:~/pjproject-1.0.3/pjsip-apps/bin 122% ./pjsua-x86_64-unknown-linux-gnu --play-file output_segment_004.wav 22:14:06.456 os_core_unix.c pjlib 1.0.3 for POSIX initialized 22:14:06.458 sip_endpoint.c Creating endpoint instance... 22:14:06.458 pjlib select() I/O Queue created (0x12c8b10) 22:14:06.458 sip_endpoint.c Module "mod-msg-print" registered 22:14:06.458 sip_transport.
