Is it possible to associate specific phone numbers to a specific PRI? We are currently losing the copper connection into our building and it costs to much to reestablish them. So all of our phone connections will be thru a fiber connection to the CO. We still have some modems, which run 24 hrs. a day, that were connected to dedicated POTS lines. They had dedicated POTS lines because they took up space on our PRI's. They still need the modems to work, but I don't want them back on the regular PRI's. Will it work if I had another PRI installed and dedicated the circuits just to those modems? Does anyone know if this is possible?
