anyone using ip phones in a business place?

I just noticed that you wanted to tie them to your existing PBX. It can be done, but that adds a another big layer of complexity. They won't be an extension on your network, but you should be able to bridge calls to them using a system speed-dial setting or something like that. If your existing PBX has any VoIP capabilities, that would be ideal.
