* RFC 3261 8.2.6.2.
* The From field of the response MUST equal the From header field of

*
* If a request contained a To tag in the request, the To header field
* in the response MUST equal that of the request. However, if the To
* header field in the request did not contain a tag, the URI in the To
* header field in the response MUST equal the URI in the To header
* field; additionally, the UAS MUST add a tag to the To header field in
* the response (with the exception of the 100 (Trying) response, in
* which a tag MAY be present). This serves to identify the UAS that is
* responding, possibly resulting in a component of a dialog ID. The

* and provisional (again excepting the 100 (Trying)). Procedures for
* the generation of tags are defined in Section 19.3.
*
* RFC 3261 12.1.1.
* When a UAS responds to a request with a response that establishes a
* dialog (such as a 2xx to INVITE), the UAS MUST copy all Record-Route
* header field values from the request into the response (including the
* URIs, URI parameters, and any Record-Route header field parameters,
* whether they are known or unknown to the UAS) and MUST maintain the
* order of those values.
