Thanks for the info Mike. Unfortunately the Asterisk box is not the end I have control over. If we were using Asterisk on both ends (rather than Cisco) we would have no issues.<br><br>Dennis<br><br><div class="gmail_quote">

Hi Dennis<br>
<br>
It would seem to me that you should be able to handle this in Asterisk
by configuring Asterisk to handle these calls via its internal NAT
systems. Have you tried setting the sip.conf account to nat=yes for the
calls from the Cisco UC520 ?<br>
<br>
Email me direct as it would be better to keep Asterisk related
conversations of this list.<br>

<br>
I have a VOIP system (Cisco UC520) behind NAT on my LAN. I need to
setup a couple of extensions that are on the public Internet (Asterisk
based). The issue that I am trying to deal with is that the local VOIP
system sends INVITES with a private IP as it is unaware of what the
true public IP is.<br>
<br>
In my search for a way to dela with this I ran across OpenSIPS. I am
wondering if I can use OpenSIPS as a proxy and/or could I use it to
re-write the IP in the SIP packets to the proper public IP?<br>
<br>
Any advice you can give as to how applicable OpenSIPS is to this task
and if so, which function of OpenSIPS would be best suited to this
problem.<br>
<br>
Thanks,<br>
<br>
