Bridged Appearances

If a station user who is active on a bridged appearance makes a conference or transfer, the user receives enhanced displays based on the Class of Restriction (COR) of the user's station, not the station with the primary extension.

12-party conference

For the 12-party conference feature to work, you must meet the following requirements in addition to configuration in the Feature-Related System-Parameters page:

• Avaya Aura® Media Server must exist in any of the connected network regions of the parties that wish to be part of 12-party conference.

• Distributed Communication System (DCS) must be disabled in Feature Administration page of Communication Manager licensing in SMI as well as in SAT.

• If you are using ASAI, then the ASAI link version to AES must be 11 or above.

Trunk-to-Trunk Connections

If you do not allow trunk-to-trunk connections on your system, the system drops all conference participants when:

• A user disconnects.

• All the other participant connect to the conference through trunk lines.

Loss Plan on Conference Calls

The end-to-end total loss for multiparty conference calls that is administered on the Location Parameters screen is not always applied to a specific call. The loss applied to a three-party conference call, for example, is calculated by adding the fixed pairwise loss for each pair of ports to the value for two-party loss shown on the Location Parameters screen. If this total is less than the end-to-end total loss value configured for a three-party conference, calculate the difference, and divide the difference by 2. Add 1 to this figure, and the result is the amount of loss applied to the call.
