Features
Features
The versatility and power of the system are due, in large part, to the variety of
feature settings and services it can provide.
Features include traditional items (Transfer and Call Waiting), as well as
advanced features (Coverage and Park).
Some functions can be performed in several ways. For example, the system
offers a variety of ways to provide call coverage. You therefore choose and set
up features according to your specific business needs.
Chapter 4, "Features and Applications," provides additional information about
features. The Feature Reference provides detailed information, including
interactions of features.
Applications
Numerous add-on products ( applications ) are available to enhance the system,
including:
Voice messaging systems answer incoming calls, provide callers with a
menu of choices, such as people or departments, and then transfer the
call as prompted by the caller using a touch-tone phone. Voice
messaging systems may or may not include voice mail services,
described below.
Voice mail services enable system users, for example, to send voice
messages to other users, forward voice messages with comments, and
return a call.
Fax messaging services automate the sending, receiving, call-handling,
and storage of faxes, in much the same way voice messaging systems
handle voice messaging.
