Hi Alan!
That's the correct behaviour. Please read RFC 3263. If the URI contains a port, e.g. inside.acme.com:5060 there must not be an SRV lookup. Because the SRV lookup leads to a port, which is already defined.

after rewritehostport("inside.acme.com:5060"), SER only does an A lookup

How can I get SER to consistently do SRV lookup after rewriting of R-URI?
