I am trying to set a 2811 with ios c2800nm-spservicesk9-mz.124-11.T to forward all calls coming in on one of the FXO ports to our contact center. All gateways are MGCP. When you set a connection plar to the correct extension and then call that POTs phone number, it will ring once then go to a fast busy. If you enter in a phone number to the connection plar it works fine and forwards to that number. I am at a loss here.
