Yeah that's the expected behavior although I guess I can change it.  I
figured that if there was a user already specified in the contact uri that
overwriting it with something else was probably not a good idea.    Now
that I think of it though, I was thinking more from sending messages
upstream to a provider not downstream to a client.

So what should the behavior be?  To construct the Request URI replace any
user in the contact URI with the user or number specified in the
MessageSend call?
