I am using a Cisco 3002 hardware client with a 3000 series gateway from NY to Malaysia... True VPN / IPsec between the 2 sites... We put VoIP across this VPN, and it works unbelievably well. So much better than we even hoped it would. We have an E1 on the Malaysian end and a T1 on the NY end... So there is good bandwidth...
The VoIP hardware and software we are using is really old. It is called an ITSE server. Internet Telephony Server... Basically, the servers have NT installed, and have this ITSE software installed. They are directly connected to our switch and given a phone extension on each side of the tunnel. All we have to do is dial that extension, and it gives us a dial tone on the switch on the other side of the tunnel. There are times when it doesn't connect right away, but if you just hang up and call again, it normally works fine. I would say about 95% of the time the call sounds like a perfect international phone call. The other 5% there is too much noise and delay, but IMO that is a small price to pay for free international phone calls to literally the other side of the world. We saved $6000 a month by getting rid of the frame-relay and installing this VPN, and couldn't be happier :-) GOOD LUCK! -----Original Message----- From: Thomas N.

Cisco said this could be done, but I am not sure how this approach works in a practical internet enviroment? Thanks!
