Hi All, I am trying to Register Asterisk PBX to a SIP Server. But SIP Server gives the following response to Asterisk: "400 Bad Request" . Asterisk sends the Register Message to SIP server with the URI: "sip: domain_name_sip-server". BUT URI should be of the format: "sip: user@ domain_name_sip-server". I have configured Sip.conf file for registration as: "user: password@ domain_name_sip-server". Can anybody suggest me, how to resolve this error. Thanks in advance Dinesh -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20040610/9841ec63/attachment.htm
