Hello list, Upon running my application built with pjsip (did svn co and svn update), I see the following output on terminal: 19:41:58.913 os_core_unix.c pjlib 1.6-trunk for POSIX initialized 19:41:58.922 sip_endpoint.c Creating endpoint instance... 19:41:58.922 pjlib select() I/O Queue created (0x94e00e8) 19:41:58.922 sip_endpoint.c Module "mod-msg-print" registered 19:41:58.922 sip_transport.

The name-addr string reads as "user1<sip:user1 at 192.168.0.100>". Still, I get the same error. Apparently, pjsip_parse_uri() returns NULL. I found a similar issue reported by another user of pjsip (http://osdir.com/ml/voip.pjsip/2007-10/msg00082.html), but no solutions other than svn update. In my code, I am invoking pjsua_acc_config_default() as suggested by benny in response to the issue reported by the other user. Can any of the members throw some light? TIA Vin
