Core System Features
Call Return Call return allows the user to call back the last caller. The user dials *69 to
dial up the last caller.
Call Screening Call screening allows the user to block calls from a list of numbers. For
example, when an screened number calls the user, the caller will receive a
busy signal. When call screening is enabled the user’s phone set will not ring
for a screened number.
Note
For version 1.3.0 of VOCAL, phone numbers entered for call screening
must include the area code, regardless if they are local or long-distance
phone numbers. Call Processing Language does not provide a pattern
matching method that differentiates seven digit (local) phone numbers
from ten digit (long-distance) numbers.
Meet-Me
Conferencing A conference bridge is provided with a well-known phone number. Users
agree to call the well-known phone number at the same time, and are linked
up together in the same audio path. The linking is a function of the
conference bridge.
Unified Messaging The VOCAL system provides a unified messaging system whereby voicemail
messages are converted into wave files and sent to the users attached to e-
mail messages.
