In my case I have forwarded port 5060, so my SIP port is 5060 on both sides of my NAT router.

I can think of two possible reasons why the remote SIP user agent would return rport=1024. Either the device has faulty software/firmware, or there is an intervening router changing the source port number before it reaches the remote SIP user agent.
