DEFINITY ECS DEFINITY Enterprise Communications Server (ECS). The DEFINITY ECS is a
telecommunications system that routes voice and data information between
various endpoints, such as telephones, terminals, and computers. It provides
highly robust networking capabilities and includes an extensive set of standard
features, such as Attendant Consoles, Voice Processing Interface, Call
Coverage, DS1/E1 Connectivity, Hospitality Support, Recorded Announcement,
and Trunk-to-Trunk Transfer. It also allows for the addition of optional features
and upgrades to the system as business needs change.

tabs, semicolons, or other characters.
Dial Pad An Avaya IP Agent dialog box that displays the 12 characters available on a
telephone.
Dial Number button A button on the Dial Number toolbar that an agent uses to go off-hook and
initiate a dial tone or to dial the digits previously entered in the Number text box.
Dial Number toolbar A toolbar that provides a number text box, access to the phone directory, call
history, speed dial, and recent calls list. When an agent enters a string (for
example, lan) followed by Enter, a popup menu displays with a list of the

a letter, the title of the field will be changed from Number to Name.

can be reached by dialing a five-digit number. Dial plans are configured through
an Avaya communication server.
