AT&T 4.1 Telephone User Manual


 
Joining Calls
Description
This feature is available only on system phones.
Joining is adding yourself to an outside 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.) Only one other
system extension can join a call on an outside line (for a total of one outside and
two inside parties).
Related Features
Automatic Extension Privacy (#304) prevents 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 a call on one of these devices could interfere with its operation.
Any user with a PARTNER-18D or PARTNER-18 phone can use
Privacy
to
prevent other extensions from joining a call at their extension.
Considerations
You cannot join an intercom call or a conference call.
You cannot put a joined call on hold.
