How many telephones can I connect to a SuperStack 3 NBX solution?
That depends on the capacity of the Call Processor you purchase and what other line terminating devices, such as telephone company Central Office lines, are connected to the network. Three models accommodate 250, 500, and 750 devices respectively. A system with a single incoming line could support up to 749 telephones. A system with 10 incoming lines could support up to 740 telephones.
