Intercom operation
This 984 telephone is fully compatible with any AT&T Four-Line Small Business
Speakerphone 945 or 974 units you may have installed. You can use a total
of 16 945/974/984 units together as extensions in your phone system.
For details regarding this telephone’s compatibility with other AT&T phones,
please refer to Before you begin starting on page 2 of your User’s Manual,
Part 2.
Each individual phone in your telephone system MUST be assigned
a unique extension number for the intercom feature to work. See
Assign an extension number to your phone on page 5 of this Quick Start
Guide for instructions.
NOTE: If you subscribe to DSL service, please read DSL users beginning
on page 4 of your User’s Manual, Part 2 for information about minimizing
problems with this phone caused by DSL signals.
This intercom features both a single-phone page and a system-wide page. A
single-phone page alerts only one phone. A system-wide page alerts all
system phones. Any phone with the Do not disturb (DND) feature activated
will not receive a page. For detailed intercom instructions, see Intercom
operation beginning on page 83 of your User’s Manual, Part 2.
An intercom call rings at the extension called with a repeating double-ring
pattern.
A single-phone page automatically activates the speakerphone on the receiving
phone. You can deactivate the speakerphone by lifting the handset.
NOTE: If a line is in use, pressing I will place the line on hold and
activate the intercom.
