I'm having an
interesting problem with a Cisco 7960 phone, and two Asterisk servers. I'm not
sure if this problem is specific to the 7960, or even to Asterisk for that
matter.
Here's the scenario.
I have an * server at one location with a public IP address (i.e. not behing
NAT). I have a second * server and 7960 phone at another location. This one is
on a private LAN, and uses NAT to get out on to the
Internet.
I have been
successful in registering the 7960 to the local * server. There's no NAT here,
so it's easy.
I have registered
the phone to the remote * server (using nat=yes in *, and nat_enable plus
nat_received_processing on the 7960). This works fine too.
BUT, I want a line
button on the local * box, plus a line button on the remote * box. This works
too, for a while. After a short while, usually once I've completed a call
to/from the remote * box, the phone starts dishing out its public address to the
local * box, even though there's no NAT to the local one.
I hope I haven't
confused the entire list here. What I'd like is a way to specify that the phone
should use NAT translations for the remote *, but not for the local one. As far
as I can tell, the 7960 nat options are global, not per
line.
Can anyone
help?
