Hello!
Does anybody tried to work with IAX2 (client side - softphones) behind a
NATs that always increment ports?
At asterisk CLI I see:
-- Registered '12345' (AUTHENTICATED) at a.b.c.d:22269
-- Registered '12345' (AUTHENTICATED) at a.b.c.d:22289
-- Registered '12345' (AUTHENTICATED) at a.b.c.d:22351
And that clients expects problems, for example if they try to reconnect
with softphone - they can't connect any more, and so on.
Is there any workaround for such NATs (but we can't touch routers, only
asterisk side or something).

Best Regards,
Alex

It's not a problem for Asterisk unless you are doing something silly like port forwarding 4569/UDP on your NAT router. Asterisk doesn't CARE about the source port of the client.
