Hello, I have implemented the SIP softphone using PJSIP. We are testing on Windows XP Pro SP3 However, we are getting these messages below. We are unable to solve this problem. However, we think this problem only occurred after we implemented OpenSER. However, we cannot be sure of this. Any information that you can provide would be most helpfull, Thanks, 13:14:59.281 os_core_win32. pjlib 0.8.0 for win32 initialized 13:14:59.296 sip_endpoint.c Creating endpoint instance... 13:14:59.296 pjlib WinNT IOCP I/O Queue created (00B30840) 13:14:59.312 sip_endpoint.c Module "mod-msg-print" registered 13:14:59.312 sip_transport.
