anyone using ip phones in a business place?

[davemchine]

I have a pbx at our main location but we also have a remote office that will soon be staffed with three people. I'm wondering if I could hook up a few analog ports from the pbx to some type of box that would allow me to put ip phones at the remote office? That would keep those three people essentially on the same phone system, able to transfer calls etc.

Thoughts?
