Hello, I am using the pjsua application to connect another machine in a LAN for a peer-to-peer call. I have checked all the playback and recording functionalities locally at both ends and all are perfect. When I call another machine with IP address, the call gets connected and prompt is received at the rcvr end for answering the call. Then it asks to send a code (100-699) and after sending no sound is heard either ways. I would like to know what does this code (100-699) imply! Also, in the whole process only beep sound is heard continuously. I am printing the console messages at both ends. At call initiator end: ****************************************************************************** [user at localhost bin]$ ./pjsua-i686-pc-linux-gnu sip:192.168.0.16 15:43:40.044 os_core_unix.c pjlib 1.0.3 for POSIX initialized 15:43:40.045 sip_endpoint.c Creating endpoint instance... 15:43:40.045 pjlib select() I/O Queue created (0x915b1d0) 15:43:40.045 sip_endpoint.c Module "mod-msg-print" registered 15:43:40.045 sip_transport.
