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.
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.
