      your all conns are *received*, so you can check for the dst port

                    <br>
                    That's a very good point. And the only way to do
                    this would be by some extension in the
                    remove_ip_port() to skip certain contacts, maybe
                    based on some branch flag (bflag).....Currently
                    there is no way to do this kind of skipping with the
                    existing code.<br>
                    <br>
                    Maybe a crazy idea here....to use 2 usrloc
                    domains/tables, like "location" for regular contacts
                    and "location-pn" for the push notification
                    contacts. You do (based on E_CORE_TCP_DISCONNECT)
                    removal only from "location"...and when you do
                    lookup, you do from both ..  Again, crazy idea :)<br>
