GENBAND’s Multiple Appearance Directory Number -
Single Call Appearance
When the unified conference station is registered with the GENBAND server, you can use the Multiple
Appearance Directory Number – Single Call Appearance (MADN-SCA) feature to share a single line with
other contacts as a member of a Multiple Appearance Directory Number (MADN) group. System
administrators assign members to MADN groups, which can have a maximum of 32 members. Check with
your system administrator to find out if this feature is available on the unified conference station.
Any MADN group member can place, answer, hold, resume, or barge in on a call on a shared line.
Additionally, all group members can view the status of a call on the shared line on their phones.

● Barge In on an Active Call
● Resume Held Calls
● Enabling Privacy
