[cisco-voip] H.323 Gateway Failover Testing

[Erick Bergquist]

With a H.323 gateway, the call manager doesn't know
what hardware, ports, controllers, etc are in the
gateway. The call manager just sends messages to the
gateways IP address and it's up to the gateway to
handle the call. The dialpeer, etc config on gateway
is how that is done. 

Are there multiple dial-peer matches for the digits
sent by call manager in the gateway and the call maybe
went out another port, etc?
