Voice mail
1
Voice mail is an information tool designed to facilitate 
communications within and outside of organizations. It 
is similar to electronic mailing, faxing, etc. The charac-
teristic feature of voice mail is that communications are 
carried out by means of voice. More specifically, the 
main advantage of voice mail is that it allows the user to 
be accessible at any time, answering and receiving calls 
while maintaining other personal and direct communi-
cations. 
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.
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 the System configuration. When there is 
a message in the mailbox, the extensions that belong to 
this group receive a MWI (Message Waiting Indicator) 
from the external voice mail server.
[1] This feature is only available when the HiPath 1100 is connected to 
a voice mail server. This can be an organization’s own internal serv-
er or it can be part of the services provided by a local carrier. Voice 
mail Servers provide a wide range of features. We recommend 
reading the Instruction Manual to familiarize yourself with the ser-
vices provided and how to use them correctly.
