Understanding Cisco CallManager Trunk Types
Trunk Types in Cisco CallManager Administration
Your choices for configuring trunks in Cisco CallManager depends on whether the IP WAN uses gatekeepers to handle call routing. Also, the types of call control protocols that are used in the call-processing environment determine trunk configuration options. You can configure these types of trunk devices in Cisco CallManager Administration:
1. H.225 Trunk (Gatekeeper Controlled)
2. InterclusterTrunk (Gatekeeper Controlled)
3. InterclusterTrunk (Non-Gatekeeper Controlled)
4. SIP Trunk
H.225 Trunk (Gatekeeper Controlled)In a H.323 network that uses gatekeepers, use an H.225 trunk with gatekeeper control to configure a connection to a gatekeeper for access to other Cisco CallManager clusters and to H.323 devices. An H.225 trunk can communicate with any H.323 gatekeeper-controlled endpoint. When you configure an H.323 gateway with gatekeeper control in Cisco CallManager Administration, use an H.225 trunk. To choose this method, use Device> Trunk and choose H.225 Trunk (Gatekeeper Controlled).
You also configure route patterns and route groups to route calls to and from the gatekeeper.
InterclusterTrunk (Gatekeeper Controlled)In a distributed call-processing network with gatekeepers, use an intercluster trunk with gatekeeper control to configure connections between clusters of Cisco CallManager systems. Gatekeepers provide call admission control and address resolution for intercluster calls. A single intercluster trunk can communicate with all remote clusters. To choose this method, use Device> Trunk and choose Inter-Cluster Trunk (Gatekeeper Controlled) in CiscoCallManager Administration.
You also configure route patterns and route groups to route the calls to and from the gatekeeper. In this configuration, the gatekeeper dynamically determines the appropriate IP address for the destination of each call, and the local CiscoCallManager uses that IP address to complete the call
