We are currently quoting a customer for a UC520 to replace a legacy PBX installed with 18 POTS lines.
I have been finding contradictory info in regards to the max # of POTS lines for the UC520.
This document says 12 max POTS lines:
But the SBCS Pricing tool says that the max is 8 with the additional 4 port FXO card.
- What is the total number of POTS lines available?
- What can we offer this customer if they insist on keeping their 19 inbound phones lines?
It has 8FXO built in, and an expansion slot left for 4 more FXO.
It has 8FXO built in, and the expansion slot is filled with a 4 FXO card.
Look near the bottom of that link.
