The whole process is in RFC 3263, "Locating SIP Servers". See section 4: The procedures here are invoked when a client needs to send a request to a resource identified by a SIP or SIPS (secure SIP) URI. This URI can identify the desired resource to which the request is targeted (in which case, the URI is found in the Request-URI), or it can identify an intermediate hop towards that resource (in which case, the URI is found in the Route header). The procedures defined here in no way affect this URI (i.e., the URI is not rewritten with the result of the DNS lookup), they only result in an IP address, port and transport protocol where the request can be sent. > Also would the "To" field be affected by any chance? No forwarding process ever changes to To header, except that a UAS can add a to-tag.
