<DIV><SPAN class=743500122-17022004><FONT face=Arial size=2>Ok, I have looked at
all of the suggestions made on this list for setting up a simple SIP proxy, but
I am still confused. Perhaps if I fully explain what I am trying to do,
then maybe someone could point me in the right direction. I am trying to
use a proxy to help to secure a Cisco PSTN gateway. I currently have the
Cisco setup to block all voice traffic, except for certain IP's. This
works fine for most cases, but we a have a customer that has a server
that "releases" the call, so I have no idea what IP's their phones are
coming from. This causes their calls to be blocked. I hope
someone out there has some ideas on where to point me, or has experienced this
before.</FONT></SPAN></DIV>
