So I have a customer who owns 40 pizza restaurants, each has 2 phone lines, when the customer calls the phone number of each location the first phone rings, then if busy the second phone rings (hunting lines). They are paying aprox $350 per month per store and use about 250 minutes on average per month.
What voip solution/provider can I go with, where I will be able to port the main line from each location and be able to use a 2 port ATA device with 2 POTS dumb phones plugged into it, where they will hunt like before? I use callcentric at my office, but their price is a little high I think... Any opinions?
