Do we really need "keep alive" messages every 10 seconds to every UA that has ever been called or from which we have had an incoming call. I know they are harmless except that they drain the battery on mobile devices. This even happens after IP - IP calls on the LAN. The KA's continue even after a UA goes offline which then results in ICMP messages from the node. Although I am behind a NAT I configure Linphone as if I had a direct connection to the internet. Let's face it. Almost all service providers are quite adept at discovering your NAT and generating KA's or scheduling fairly frequent registrations. Am I missing something? Is the described behaviour justified? Rob
