[Linphone-users] Excessive "keep alive" messages

[Robert Dyck]

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?
