One-Way Broadcast Speaker Call
The One-Way Broadcast Speaker Call feature lets you make a one-
way call to the speakers of up to 40 phones that are multiple line
appearances of the same extension. To use this feature, you must be set
up for it on your communications server.
Note: One-Way Broadcast Speaker Call is only available on Version
6.3 and higher.
Any multiple line appearances that are busy are dropped from
the call.
If the extension called is busy, the caller will hear a busy tone
and the call will not be completed to the extension or the
multiple line appearances.
If another line on the phone with the extension is busy and the
extension itself is free, a one-way broadcast speaker call will
be completed to the multiple line extensions. It will not be
completed to the extension.
