it came to my mind that if sip ua runs on the same host as sip proxy (which is very common in test environments at least) then it seem that is_first_hop does not work for replies.

it may not be a good idea to introduce this function for replies if it has such a hole.

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.
