Problem Description

The following feature is deprecated and is not supported by Cisco Unified Communications Manager (Unified Communications Manager), Release 15. If you are using this feature currently in your deployment and you are trying to upgrade to Release 15, you will not be able to use this feature after the upgrade.

  • H.323 Gatekeeper Control options

Background

Unified Communications Manager has provided support for H.323 call control signaling since the introduction of voice features about 20 years ago. Currently, customers use the Session Initiation Protocol (SIP) for multimedia session control and hence minimal demand for the H.323 functionality.

In acknowledgement of this reduced demand, Unified Communications Manager will not provide support for the H.323 Gatekeeper Control options from Release 15 onwards.

Also the H.323 call control features in Cisco IOS XE Software are past the End of SW Maintenance Release dated May 30, 2022. For more information, see https://www.cisco.com/c/en/us/products/collateral/unified-communications/unified-border-element/bulletin-c25-2479306.html.

Problem / Symptom

If you are using this feature currently in your deployment and you are trying to upgrade to Release 15, you will not be able to use this feature after the upgrade.


Note
H.323 gateways and H.323 protocol continue to be supported.

Product Migration Options

Customers are encouraged to migrate to SIP trunk with Location Bandwidth Manager (LBM).
