Administering Sharing Mapping among Communication Manager PBXs for Extension to Cellular

Last Updated : Mar 05, 2021 |

About this task

With the Sharing Mapping among Communication Manager PBXs feature, you can share station name and station mapping information with multiple Communication Manager servers. A Communication Manager server acquires mapping information from other Communication Manager servers by using a SIP subscription. Communication Manager subscribes for the shared mapping on the Off-Pbx-Telephone Mapping-Subscriptions screen. SIP trunks or Subscription Aggregator is used to interconnect Communication Manager servers to share mapping information. Each Communication Manager server can make up to 3 subscriptions.

Procedure

  1. Type change off-pbx-telephone mapping-subscriptions. Press Enter.

    The system displays the Mapping Subscription screen.

  2. In the Signaling Group field, specify the signaling groups for a far-end domain of PBX or subscription aggregator.
  3. In the Level field, specify the subscription level for a far-end PBX or subscription aggregator.
  4. In the Maximum Percentage of Mapping Storage Allowed for Acquired Mappings field, specify the maximum percentage of mapping storage that is allowed for the acquired mappings.
    Note:

    Mapping storage is shared between Administered Mappings, Acquired Mappings, and ONE-X Mappings.

    You can use the list mappings-acquired command to list acquired mappings.

  5. Using the off-pbx-telephone station-mapping command, go to page 3 of the Stations With Off-PBX Telephone Integration screen. Compare the subscription level with the share level. If the share level is less than the subscription level, the system discards the mapping.

    The information on this page maps to the information that you have entered in the Station Extension and the Application fields on the first page.
