We are a small business with 4 POST lines connected to a 3Com NBX 100\n(4.2.7) for voice and one dedicated T1 conected to a Cisco 1721 for\ndata. We also have a GTA GB-Ware firewall handling our LAN and DMZ.\nSeveral companies such as Vonage and AT&T are offering now VoIP\nservices in our area. The NBX documentation says that the unit can be\nconnected directly to the WAN using an external router supporting IP\nToS. My question is: can we connect the NBX unit to the WAN to receive\nservice directly from Vonage or AT&T without ATA adapters? (It would\nseem silly to convert VoIP to POST and then to VoIP immediately).\n\nTIA,\n\n-\-\-Mirco.
