I have a customer who owns a Macco dealership they have an Aspire M with Pots lines
They use Comcast

According to the customer the cooperate office can record all calls get reports on how many calls are answered, ect

there is no equipment on site

the local customer ordered the lines thru Comcast they pay the bill

The only thing I can think of it corporate does require them to install there MOH Source which is connected to the internet

just wondering
