The point is:
You can do the routing based on the SIP data (Route and RURI) or you can send a 
request wherever you want, regardless of the SIP request data.
A load balancer proxy could route requests to a proxy/gateway regardless of the 
RURI or Route headers without changing them.

Since the RURI can mean the way a request was routed to the registrar, if the 
registrar is listening in 5080 it should allow a RURI with port 5080.

But this is not required, and the UAC could send:
  REGISTER sip:[EMAIL PROTECTED] SIP/2.0
to domain:5080 with no problem. This would occur if the UA has an outbound 
proxy set or a registrar set in domain:5080.
