Personalized Ringing; Message Waiting Indication - Avaya IP Office 8.1 Product Description

Direct Inward Dialing (DID/DDI)
This relies on the local telephone exchange passing all or part of the dialed number to the IP Office. This
number can then be used by IP Office call routing software to route the call to an individual phone, or groups of
telephones. This service is typically used to reduce the workload on a reception position by giving members of
staff or departments individual numbers so they can be called directly. For convenience it is common to have
the extension or group number the same as the digits supplied from the network, but IP Office can convert the
number to a number as needed by the business, within limits
In North America, T1 circuits are required for DID.
Transfer
Call Transfer allows users to transfer a call in progress to another phone number – either internal extension or
external public number. The caller is placed on hold while the transfer is performed.
If the phone is put down before the destination has answered, the original caller will be automatically
transferred. This is called an Unsupervised or Blind Transfer. Alternatively, a user can wait for the destination to
be answered and announce the transfer before hanging up to complete the transfer. This is called a Supervised
Transfer.
Unless restricted by the system administrator, the IP Office makes no differentiation between internal or
external call transfers.
Distinctive and Personalized Ringing
The IP Office uses different ringing sequences to indicate the type of call, for example whether internal or
external. This feature is called 'distinctive ringing'. For analog telephones the distinctive ringing sequences used
are adjustable. For digital and IP telephones the distinctive ringing sequences are fixed as follows:
Internal Call: Repeated single-ring.
·
External Call: Repeated double-ring.
·
Ringback Call: Single ring followed by two short rings.
·
This ring is used for calls returning from park, hold or transfer. It is also used for call back when free and
voicemail ringback calls.
This feature is supported across the

Personalized Ringing

In IP Office the term personalized ringing is used to refer to changing the sound or tone of a phone's ring. On
many Avaya digital telephones, the ringer sound can be personalized. Changing the ringer sound does not alter
the ring sequence used for distinctive ringing. This feature is local to the telephone and not supported on all
types of telephones.

Message Waiting Indication

Message waiting indication (MWI) is a method IP Office uses to set a lamp or other indication on compatible
telephones when a new message has been left for the user, either in a personal voice mailbox or in a group
mailbox or call back message. When the message has been played or acknowledged, the lamp is turned off.
All Avaya digital and IP telephones have in-built message waiting lamps. Avaya one-X™ Portal for IP Office
provides message waiting indication on screen.
For analog telephones, from IP Office 3.1 a variety of analog message waiting indication (MWI) methods are
provided. Those methods are 51V Stepped, 81V, 101V and Line Reversal. The MWI method must be selected
from the IP Office Manager when configuring a system to match the properties of the analog telephones. Note
that the 101V signaling is only available on IP500 Phone cards and expansion modules plus version 2 IP400
Phone 8, 16 and 30 expansion modules.
