Have received a referral from a CG buddy of mine to take over a client with 2 locations. 1 MICS with 8 copper lines and 1 CICS with 2 lines. OK, spoke with client, they were sold 2 NT9B10aaaa gateways,to use to connect systems,They use Comcast vpn between sites and were told these work well for systems,my searchs here seem to say otherwise. Any help or pms would be great.Thanks----John
