• CO-to-CO Line Call Duration
The length of outside-to-outside (CO-to-CO) line calls may be limited through system
programming.
Both the outside caller and the outside destination will hear a warning tone 15 seconds
before a specified time limit. When the timer expires, the call is disconnected.
• To return to the held call before the destination answers, press the TRANSFER button
or corresponding CO/INTERCOM button.
• After transferring the call to an outside party, you can join the call by pressing the CO
button that you used to transfer the call. A 3-party conference call is established
(Conference).
• To change the transfer destination before going on-hook, press the CO button whose
indicator is flashing slowly to retrieve the call, then repeat the Call Transfer procedure.
