But to the original question… Most big VoIP gateway vendors offer a C7 solution these days. My company is using Clarent that works very well, but there are others including Cisco. Some would include a C7 card in the gateway while others use a separate C7 server box which the GW or softswitch talks to over IP. I dont agree with Appans comments. A C7 option adds to the cost of your VoIP gateway, but this is nowhere near the cost of a C7 carrier class switch.
