I realize this last email has no useful information, so let me elaborate. I have a Kamailio server on AWS with an internal IP of 10.20.30.40 and it has an external elastic IP of 55.66.77.88.
When a SIP client subscribes it sends the initial subscription to user@realm (where realm resolves to 55.66.77.88) , then it gets a notify with a new address <sip:10.20.30.40:5060;transport=udp> . The client attempts to refresh the subscription, but we are now sending the subscribes to this new contact which will time out. 300 seconds later, we subscribe again to user@realm and contacts show up. Other stuff like rtp, inbound/outbound calling all work properly.

When subscribing to presence the contact is sent out with the internal IP rather than the external public IP. The subscribes are being sent to it with the external hostname ( which resolves to the external IP ). Where would I be able to change the IP sent in the Contact header ?
