What is the easiest way to setup an IP phone at a remote site by using the internet? I have a phone lab with a 2621XM router connected to the internet and I have a 501 PIX at home. I'd like to try and setup a phone at home off of my lab system by using the internet. QOS isn't a big concern, I'm just doing this as a test/learning experience. Thanks!
It's a fairly simple thing to do if you understand VPNs and follow a couple of rules.
As you say, QoS won't be possible in this scenario so expect inconsistent (but probably poor) performance!
Basically just set up a VPN from your remote site to the head office. Make it a LAN-to-LAN type tunnel - i.e. one using fully routable addresses on both ends. This type of tunnel will not use NAT on any VPN traffic. If you use NAT, you will normally run into trouble with setting up calls in one direction or get one-way voice issues etc.
If you have a LAN-to-LAN tunnel (network-extension mode in EzVPN terminology) you neatly dodge this issue.
If you have the VPN and routing set up correctly you just need DHCP/option150 set up and you should have a working system.
I'd suggest you get the VPN working, and post back if you have specific issues.

Thanks for the quick reply. Do you have a basic config for the router and PIX that I can reference to setup the VPN? If it helps at all with the config, I have both sites setup with dynamic DNS (http://freedns.afraid.org/) since they are both on cable internet without static IPs. All though the IPs RARELY change. Thanks!

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
