Question

What is the per seat cost of an IP telephone system for a call center?

Answer 1

That is a wide-open question...

Depends on IP telephony service provider and their rates, which vary from provider to provider.

Add the sum of the (costs of Internet service + cost of IP phone service + per line cost by provider + cost of equipment + other operating costs) divided by (number of seats).  

Very roughly speaking, that would be the per-seat cost.
