Avaya Modular Messaging Concepts and
Planning Guide
! On systems without DID, callers call the automated attendant
from the fax machine, select the extension of the subscriber either
by using Dial-by-Name or by entering the extension of the
subscriber, and press Start on the fax device.
When an MAS receives a call and detects the fax tone, it transfers the call
to the third-party fax server. When the fax server answers the call, the
MAS plays the fax routing information inband to the fax server. Based on
the fax routing information, the fax server then delivers the fax message
to the mailbox of the recipient.
Note: The fax server must support dual tone multifrequency
(DTMF) routing.
Requirements for fax server interoperability with Avaya Modular
Messaging
Avaya recommends that the third-party fax server resides on a separate
server. The fax hardware is connected to a fax hunt group on the switch.
The following are the requirements for third-party fax server
interoperability with Avaya Modular Messaging:
! The fax server must be integrated with the mail system as an
e-mail connector or an e-mail gateway for fax.
! The fax server must use addressing that is specific to Avaya
Modular Messaging:
— With Microsoft Exchange, use a FAX addressing type
specific to Avaya Modular Messaging.
— With IBM Lotus Domino, use a specified foreign domain
name for the right-hand part of an address. For example,
nnnnn@FAX, where FAX is the foreign domain name.
This addressing is necessary to deliver messages to the fax server
for transmission and to create one-off or ad-hoc addresses.
! The fax server must support dual tone multifrequency (DTMF)
detection and collection.
! The fax server must match the DTMF fax routing number
supplied by Avaya Modular Messaging with the fax routing
address of a subscriber.
! The fax server must create faxes as e-mail messages with TIFF
attachments and send them to the intended recipient.
