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 :)
SIP ALG routers are big pain, at least for me :-)
What I'm trying to do is automagically detect users behind such a stupid routers (analyzing INVITEs and REGISTERs in sip-dump) and automatically send them e-mails aksing to disable SIP ALG. Just my 2c...
some do not offer any such option, even I googled a lot some time ago, I couldn't get a solution for a siemens gigaset se36
errata: gigaset se361 ...

. If someone knows, would be great.
However, it was easy to trick by listening on 5062 with kamailio and pointing my phones to use that dst port. I haven't tried with tcp, another option that should be tried with those algs.
