The Gateway Gatekeeper exam assesses the knowledge of the Systems Engineer on the implementation of Cisco gateways and gatekeepers to integrate a VoIP network to both PSTN and TDM equipment. This includes implementing dial plans and advanced gateway features such as SRST and DSP resources. The exam also covers implementing gatekeepers and directory gatekeepers to provide hierarchical dial plan resolution and call admission control.
