No, it is not. At least if your user agent and other servers
implement the same RFC 3261 as most of the other SIP servers in the
world do.

Well, rewritehostport() changes the request URI, not the URI part of
the To header field. This is fine for most applications, but if you
really want to change the contents of the To header, you will have
to use something like replace_hf(). But it is not recommended to do
that. Really. SIP is designed to work without replacing the To. In
fact, applications are more likely to break if it is changed.
