LRQ Transit Regions

LRQ transit regions are a special type of VRC managed region containing only directory gatekeepers (DGKs).

Use LRQ transit regions in your dial plan to set up a DGK hierarchy. Hierarchical DGKs describe an H.323 network configuration where multiple levels of DGKs are in the LRQ forwarding path.

Regular VRC managed regions assign outgoing connections to LRQ transit regions rather than directly to one another.  LRQ transit regions can be configured to forward LRQs to yet another LRQ transit region, achieving another level of indirection in the LRQ forwarding hierarchy.  This pattern is continued for as many levels of DGKs as necessary for your dial plan.

You can assign separate administrative privileges for each LRQ transit region to distinguish administrative groups between regions.  

Use this procedure to configure an LRQ transit region in your dial plan.
