Features affected by the increase in locations and network regions

Last Updated : Feb 16, 2016 |

The increase in the number of network regions and locations can affect the following features:

  • Dial Plan Transparency (DPT): The DPT feature can work in a stub network region only with endpoints. Stub network regions use the media processing resources of the core network regions that the stub network regions connect to. Administer the DPT feature in a core network region that is directly linked with other stub network regions. Only then can the endpoints in the stub network regions connect to endpoints in other network regions.

  • Inter-gateway Alternate Routing (IGAR): Any stub network region from 1 to 250 can use IGAR if the stub network region contains a branch gateway or a port network. IGAR is unavailable for stub network regions from 251 to 2000.

  • Emergency Calling: When an endpoint in a stub network region dials an emergency number, Communication Manager analyzes the dialed number. Communication Manager then uses the ARS location table to route the call to the destination. The call is routed using a predefined route pattern.
