So how is everyone dealing with NAT issues, then?

Our ITSP recommends NOT having sipXecs behind NAT (we are having some
problems that the ITSP thinks are NAT related), but I do not want to
have public IP addresses for all of our phones.

PS:  In case anyone cares or has any insight, the problem that we are
having is that if I call a POTS line from the SIP phone and place the
call on hold, sometimes the audio is one-way after the call resumes.  A
Wireshark trace outside the firewall shows that I still have RTP packets
flowing in both directions, but the ITSP thinks that they have been
incorrectly NAT'd.

To further add to the mystery (and seed some doubt about whether the
ITSP has correctly diagnosed the problem), the problem only occurrs when
the call is placed on hold from my Polycom IP550.   If I make the call
from X-Lite and put the call on hold the problem doesn't happen.

I've reqested additional IP Addresses from our ISP so I can disable NAT
between the Internet and the sipXecs server.   Once I've got everything
reconfigured, I should be able to find out if the ITSP is right about
what the problem is.

If you say so chief...  have fun with that.

As far as all sipXecs services are concerned...  1 interface.

Actually it can,

I set up both my servers to be dual homed. If you are careful with
static
routing you can run your sip network internal private network and you
user
portal on an external network.  I haven't tried running sip on both
interfaces, I imagine the proxy server can do it, maybe there is a
problem
with media...?
