More than likely your Voice Gateway (2811) is registered to the Call Manager using MGCP protocal, if this is the case you have to go into the call manager and check to see if the device is still registered to CM. Chances are it's unregistered and you will have to reset it in order for calls to proceed out the gateway. In CM look at the Device -> Gateway page, find the gateway you are having trouble with and see if it's MGCP or H323 registered.
