Interactions

Last Updated : Jul 20, 2023 |

This section provides information about how the Administrable AGL feature for Communication Manager interacts with other features on the system.

  • You can have some regions that use the pre-Communication Manager 5.1 non administrable AGL implementation, and some other regions that use the new administrable AGL implementation. But you cannot have a single network region that use a combination of the two methods. The AGL column can either contain numbers or alphabets, but not both. The field can also contain blanks. Blanks are ignored by both the old and the new implementation of this feature.

  • This feature only applies to H.323 IP telephone registrations and H.323 IP telephone AGLs. The H.323 gateways also register to Communication Manager. This feature does not affect how the gateways obtain and use their own lists of gatekeepers. This feature does not impact on how IP (SIP) telephones register to SM.

  • If an extension number has shared control using the server between an H.323 IP telephone and an H.323 IP softphone, Communication Manager displays both the AGLs that were sent to the H.323 telephone and H.323 softphone.

  • In prior releases of Communication Manager, the AGL feature only included PROCRs from the same region and from directly connected regions. The AGL feature included PROCRs from all indirectly connected regions if there were no PROCRS in the same or directly connected regions. With this enhancement, it is now possible to explicitly administer Communication Manager to include PROCRs from indirectly connected regions as well. Also, if you administer a non-zero value in the AGL column for an indirectly connected region, it opens that indirectly connected region PROCRs to be eligible to be used for load balancing.

  • In general, when using the Communication Manager Administrable AGL feature, PROCR priorities should not be used. Note the following information:

    • For TTS telephones, Communication Manager enhanced feature considers priorities, PROCR socket load, PROCR’s service state, and whether the H.323 IP telephone registration can use PROCRs for load balancing.

    • For non-TTS telephones, priorities and PROCR socket load are taken into account when load balancing.

    • For TTS and non-TTS telephones, the Communication Manager enhanced feature does not take either priorities or PROCR socket load into consideration when building the AGL.
