Repeat this procedure for all Cisco Unified CM clusters.

Conferencing in Hosted UCS

Note If Hosted UCS7.1a is deployed without Hardware Conference Bridge and Transcoder, the CUCM clusters must be configured with following device region associations, for the ad-hoc conference to work using CUCM software conference bridges. The steps mentioned in this sections is to be performed after provisioning HUCS 7.1a deployment

In HUCS7.1a, three-way ad-hoc conferencing is tested with the configuration as follows:

Procedure:

Step 1 Check the Regions of software Conference Bridge and H.225 GK controlled trunk to HSI on CUCM clusters.

Step 2 If there is no association between these two regions, configure the inter-region relationship codec to be G.711. This is because, intra-region codec is G.711 and inter-region codec is G.729 by default on CUCM. Hence, configuring G.711 to be inter-region codec for these two regions enables the conference call to use G.711 and makes it work.
