Joining Calls
Description
Joining is adding yourself to a call in progress, the same way you do on a home
telephone by picking up an extension. (This is different from conferencing, in
which the originator “pulls you into” the call.) Up to three system extensions can
join a call on an outside line (for a total of one outside and four inside parties).
Related Features
■ You can use Automatic Extension Privacy (#304) to prevent other
extensions from joining calls on a specific extension. This is especially
useful for answering machines, fax machines, modems, and credit card
scanners, because trying to join one of these devices could interfere with
its operation.
■ Users can program Privacy onto a system phone button to allow or prevent
others from joining their calls as needed.
■ Caller ID information displays if you join a call; however, you cannot join a
call at any extension that has Privacy activated.
■ If a line is not assigned to a user’s extension and access to that line is not
restricted for that extension, the user can use Direct Line Pickup—Active
Line to join a call on that line.
■ You can join a call answered by Automatic System Answer or Direct
Extension Dial by pressing the line button and lifting the handset. The
message stops playing when you join the call.
■ Pooled extension users can add other parties to a call by pressing pool
buttons.
Considerations
■ You cannot join a call by pressing a pool button.
■ You cannot join an intercom call or a conference call at another extension.
■ You cannot join a call on an extension that has a voice interrupt on busy call
in progress.
■ You can join a call that is being answered by the voice messaging system,
but only if Automatic Extension Privacy is Not Assigned for the extensions
associated with the voice messaging system hardware. If this is the case,
when you join the call, the voice messaging system disconnects
automatically so you can speak to the caller.
■ You cannot put a joined call on hold.
■ You can tell when someone has joined a call of yours when the lights next
to the line or pool button change to alternately flashing red and green.
■ If a system phone joins a call on a standard phone, there is a momentary
“break” in the call on the standard phone.
