| Privately call a co-worker while you’re busy on your handset. |
While on a handset call, Reverse Voice Over lets a busy keyset user make a private Intercom call to an idle co-worker. The busy user just presses and holds down a programmed Reverse Voice Over key to make a private call to the assigned co-worker. The initial caller cannot hear the Reverse Voice Over conversation. The private Intercom call continues until the Reverse Voice Over caller releases the key again. The initial handset call can be an outside call or an Intercom call. An extension can have Reverse Voice Over keys for more than one co-worker.
Reverse Voice Over could help a salesperson, for example, when placing a call to an important client. The salesperson can talk with the client and give special instructions to an assistant — without interrupting the initial call.
Reverse Voice Over uses a system Conference circuit while it is active. The following table shows the system’s Conference capacities:
| Description | Capacity |
| Conference circuits | 32 |
| Maximum simultaneous users in Conference (total of all Conferences system-wide) | 32 |
| Maximum simultaneous conferences | 8 |
| Maximum parties in any one Conference (lines and/or extensions) | 8 |
The system’s 32 Conference circuits are dynamically allocated as users request them.
