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. 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.

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...

Please, feel free to add any useful information about infernal routers with
SIP ALG enabled.
Thanks a lot :)

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!
