The check is on ip, port and protocol, if ua is on same host, it will
use a different port. It is similar situation with record-routing and UA
on same host. Without port matching of 'myself', then contact of UA
which appears as R-URI in subsequent requests will be detected as myself
and eaten by loose_route() by considering a strict routing case.
For now use the test with rr count, it is good for replies.
