Beware that the line breaks in the SIP message are not showing in your message. > The above INVITE is getting 403 Failure response telling Calling user is not > registered. > Can this because of IP is different in Contact header? It could be because the Contact header is different, or it could be for another reason. The server is rejecting the INVITE, but not for any standard reason, so the only way to know for sure is to find documentation regarding the server or talk to someone who knows its behavior. At the least, you need to tell us the server information, e.g., the value of the Server header in the 403 response.
