Routing inbound fax calls to the third-party fax server
Like voice calls, fax calls placed to a subscriber’s extension are redirected
to the Octel Unified Messenger voice server when these calls encounter a
ring-no-answer or busy condition. Whenever the voice server receives a
call and detects that it is a fax, it places the call on courtesy hold and
initiates a call to the fax server hunt group. After a fixed time delay
(5-second default) Octel Unified Messenger sends fax routing information
as DTMF codes to the fax server and then cuts through the fax call. The
fax routing information sent by Octel Unified Messenger is determined by
retrieving the Microsoft Exchange FAXROUTE address for the
subscriber, based on the called extension number or entered mailbox
number.
After the fax server receives the fax, it determines the Exchange
subscriber’s address by finding the subscriber with a matching
FAXROUTE address. Then the fax server creates an e-mail message with
a .TIF attachment (TIFF group 3 fax format), sets the message class to
IMP.NOTE.FAX, and sends the message to the subscriber’s mailbox.
