Hello,
I just want to dwell around a couple of things.
Several vendors have "application awareness" for instance Cisco has
<fixup protocol sip...>
Hence the ser will not se the client as nat'ed and will not send nat-ping to the clients.
If the client does not support some kind of keep-alives, I guess you will loose connectivity with the clients when standard register expiry is 3600 sec. (off course until the next register message is sent)
The Cisco PIX, for instance, have a standard (however configurable) sip inactivity timer = 1800sec.
What would actually be the best way of dealing with this?
You can use a different port than 5060 for your SIP proxy. This way ALGs should not modify the packets.
