Functions used when receiving calls
Step by step
66
Users can retrieve messages:
• from their own telephones
• using an external or an internal telephone.
The voice mail server may be Internal or External. An
internal voice mail server refers to a server owned by
the company itself while an external voice mail server
refers to a facility outsourced to a local carrier.
Internal Server
An internal voice mail server works with a UCD sub-
scriber group that is configured during the program-
ming process. This is known as a VMIe group Interface.
To enable extensions to receive MWI (Message Waiting
Indicator) from the internal voice mail server you must
enable the internal MWI feature.
The configuration of a UCD subscriber group for the
VMIe group Interface must fulfill these requirements:
• It must not be programmed as a DID for an external
line
• It must not be configured for Overflow.
• The agent's auto-notes time interval must be set to
at least 5 seconds.
• Queue size must be set at the maximum allowed
(default)
External Server
A voice mail server outsourced to a local carrier works
for specified extensions grouped as a "External MWI
group" during configuration of the system. When there
is a message in the mailbox, the extensions that belong
to this group receive a MWI (Message Waiting Indica-
tor) from the external voice mail server.
