What I'm trying to understand is whether their two proposed "Centrex" 
lines will allow for the five separate "extensions" that they have now 
with their PBX.

In other words, is there any way a 2x5 PBX (with the customer paying for 
2x POTS lines) could be swapped out with two Centrex lines?

Thanks, all.  I'm learning a lot here.
