[Serusers] SIP rewriting and e.164

Has anyone done interop with a provider that requires From:, To: and URI to 
be in e.164? The problem we are having is that if our customers dial a 
ten-digit number, the To: is written by the UA as NXXXXXXXXX at site.com but we 
have no way to rewrite that as +1NPANXXXXXX at site.com before we send the 
message out. All the mailing list messages I have found suggest that it's a 
bad idea to rewrite To:. It looks like we could do it with a b2bua, but I 
want to avoid adding that extra complexity for what seems (on the surface) 
to be a simple problem. Anybody been through this? Thanks.
