/** SIP Header To.
* The To header field specifies the desired
* "logical" recipient of the request, or the address-of-record of the
* user or resource that is the target of this request. This may or may
* not be the ultimate recipient of the request. Like the From
* header field, it contains a URI and optionally a display name.
* <BR> A request outside of a dialog MUST NOT contain a To tag; the tag in
* the To field of a request identifies the peer of the dialog. Since
* no dialog is established, no tag is present.
* The original
* recipient may or may not be the UAS processing the request, due to
* call forwarding or other proxy operations. A UAS MAY apply any
* policy it wishes to determine whether to accept requests when the To
* header field is not the identity of the UAS. However, it is
* RECOMMENDED that a UAS accept requests even if they do not recognize
* the URI scheme (for example, a tel: URI) in the To header field, or
* if the To header field does not address a known or current user of
* this UAS. If, on the other hand, the UAS decides to reject the
* request, it SHOULD generate a response with a 403 (Forbidden) status
* code and pass it to the server transaction for transmission. */
