Dear All, I've downloaded PJSIP 1.1 software and followed the installation to build the software. The linux kernel version is 2.6.18-8.el5. I've successfully built the software but I'm not able to register PJSIP with Asterisk Open Source PBX. Error under PJSIP side: --end msg-- 16:43:53.255 pjsua_acc.c SIP registration failed, status = 404 (Not found) Error under Asterisk side: [Apr 9 16:58:22] NOTICE[7426]: Chan_sip_c:14491 handle_request_register:Registration from'<SIP:192.168.100.14>' failed for '192.168.100.14' - No matchine peer found Necessary configuration files attached. Any valuable suggestion is greatly appreciated. Thanks & Regards, - Senthil -------------------------------------------------------------------- mail2web - Check your email from the web at http://link.mail2web.com/mail2web -------------- next part -------------- A non-text attachment was scrubbed...
