Nevertheless, I would keep it active, and set ping_nated_only to 1, so you just ping clients which are known to be behind NAT.
The only problem with it is when a fuc**ng SIP ALG enabled router takes place. It will modify the request so it'll look as coming from public IP (NAT cannot be detected in Kamailio), but most of these infernal routers don't mantain the keepalive so the input traffic is closed after UDP "connection" expires in the router.
Yep. Infernal - well said!
This is my personal battle against SIP ALG routers: http://www.voip-info.org/wiki/view/Routers+SIP+ALG
Please, feel free to add any useful information about infernal routers with SIP ALG enabled.
Thanks a lot :)
