Hi all,

Is it valid for a REGISTER request to contain a port parameter?
e.g.  REGISTER sip:example.com:4060

I can't see anything in RFC 3261 that explicitly bans it. userinfo and @
yes, but not port. I may be looking in the wrong place.

It may be that it is implicitly banned by 10.2 but I'm not sure:
'The Request-URI names the domain of the location service for which the
registration is meant.'
I guess the port would not be considered part of the domain.

Cheers

Steve
