Here are the logs : Setting Channel with State 0 : Setting Channel with State 0 : 10:30:30.577 os_core_win32. !pjlib 2.2.1 for win32 initialized 10:30:30.594 sip_endpoint.c Creating endpoint instance... 10:30:30.594 pjlib select() I/O Queue created (006D5E00) 10:30:30.594 sip_endpoint.c Module "mod-msg-print" registered 10:30:30.594 sip_transport.
