When you say not through ISA very well are you referring to the problems you mentioned below or call quality issues? Having now been to my first (of several) IP phone meetings I was told that they don't work well through Proxy servers and that call traffic needs to be priortized over data traffic. The good news was that at least this particular system doesn't use SIP, just regular IP with TCP and UDP ports. The other good news is that I received a copy of the network documentation today and nowhere does it say open a port. It actually list ports, protocols and direction of traffic.

It seems to work OK. But, not through ISA very well. What I've noticed is that if you have incoming traffic such as email or ftp the quality dosen't hold up very well. And sometimes you loose connections to the other party. I like the technology and hope that it will continue. It's the only way to discover all the bugs.

They have 3 locations and full time people that work from home and plan to expand into 2 more locations soon so IP makes some sense for them. It will be much cheaper for them to purchase a single phone system and maintain it from one location. They are running SBS2003 and Citrix servers. Everyone connects to the main office there are no servers at the other locations. We've got lots of bandwidth at every location the remotes have 768 or 1000 SDSL and main office has 2.0 cable. Everyone has a static IP address. No bandwidth problems yet. Here are my concerns: Everyone needs to maintain good bandwidth. I'm thinking that a separate Internet line for the phones would be a good idea. Not only could it provide some redundancy in case of failure but it would preserve the existing bandwidth for applications. If I can't convince them of this or if I have to use the same cable as the computer systems then I'm also concerned about the ISA server. Should I run the phones through the ISA? Is there a reason to have IP phones behind a firewall?
