Re: Why h323 gateways drop calls in case of CCM failure
The H.323 gateway establishes a TCP connection to the active Call Manager server for the entire period of the call. In the event of a active call manager server failure, the call will get disconnected because the TCP connection between H.323 gateway and the active call manager server is lost.
MGCP will provide call redundancy as the gateway establishes connections to
both call manager servers, in the event of a active call manager server failure, the gateway will use the alternative connection to the other Call Manager server, thus the call will not be dropped in this case.
