I have several 2800 Voice Gateways in several regions. How can I protect my H.323 GW? these Gateways have public IP addresses. Can I control or Authenticate my VOIP Gateways in order to eliminate a rogue Gateway can connect to my Gateway and they can make calls?

I suggest you use access list if it's from outside.
