Avaya PARTNER ACS Installation And Use Manual page 307

When an incoming call is answered by PVM, PMVS, PARTNER MAIL, or ASA/DXD, the system
determines if the incoming call is a fax. If the system is set up to automatically route incoming fax
calls to fax machine(s), it automatically transfers the call to Hunt Group 8.
If your voice messaging system is PARTNER Messaging and you use the Fax CNG
Detection feature, do not program PARTNER Messaging to assign a fax extension to
an Automated Attendant. For more information, see the PARTNER Messaging
System Manager's Quick Reference.
Considerations
To use Fax CNG Detection, you must have a voice messaging system or ASA/DXD. You must
I
also have your system configured in one of these ways:
– PARTNER ACS Release 3.0 or later as a stand-alone module.
– 1600 DSL module in slot 1; PARTNER ACS Release 4.0 or later in center slot; any
modules in remaining slots.
– 012E/362EC module in slot 1; PARTNER ACS Release 5.0 or later in center slot; any
modules in remaining slots.
– 308EC Release 3.0 or later/200/206/400 module in slot 1; PARTNER ACS Release 3.0 or
later in center slot; any modules in remaining slots.
– 308EC module prior to Release 3.0 in slot 1; PARTNER ACS Release 3.0 or later in center
slot; at least one 308EC Release 3.0 or later in remaining slots.
– 308EC module prior to Release 3.0 in slot 1; PARTNER ACS Release 5.0 or later in center
slot; at least one 308EC/012E/362EC in remaining slots.
When lines appear on a fax extension, make sure that the fax machine does not automatically
I
answer outside calls on these lines. There are three ways you can do this:
– Set the fax machine for delayed pickup.
– Use Line Ringing to change the ring options on the fax extension to either delayed ring or
no ring.
– Use Line Assignment (#301) to remove all outside lines from the fax extension (this is the
recommended way).
Incoming fax detection is activated automatically by assigning extensions to Hunt Group 8.
I
If a PARTNER MAIL system is connected to the system and fax detection is being done via
I
PARTNER MAIL, no extensions should be assigned to Hunt Group 8.
If there are no touch-tone receivers capable of detecting a CNG tone, the call is treated as an
I
incoming voice call.
It can take up to eight seconds after a call is answered before the system determines that the
I
incoming call is a fax call. The voice messaging system message should be at least this long
so that the CNG tone can be detected before the message ends and the call can be
transferred.
You may use Automatic Extension Privacy (#304) to prevent other extensions with the same
I
line from joining a fax call at the extension and interrupting it.
