17.22. FAX1 - Call forwarding from incoming FAX CO lines to
Phonemail 
Feature:
Call forwarding from incoming FAX CO lines to Phonemail if the called fax machine
does not
respond.
Function:
An incoming fax CO line signaled under ISDN service Fax Group 3 (HLC/LLC High/Low
Layer
Capability) or from the analog network under the Voice service is forwarded to Phonemail
if
the called fax machine does not respond (e.g. out of paper).
This causes all calls for a fax machine that can be recognized as faxes to be forwarded
after a time if the FAX1 COT parameter is set in the COT of the incoming seized trunk
and
all parameters required for releasing the call forwarding and deflection features
are set.

In the case of Group 3 fax machines which are accessed from external subscribers and
under
the Voice service, it is necessary to use the AMO DIALCONV to set up a second call
number
which is then converted to the actual call number by means of the FAX service.
For OpenScape 4000 network configurations with internal subscribers outside of the
home PBX
of the Xpressions450 it should be noted that mailbox access must be set up for each
OpenScape 4000 system by means of the AMO RICHT with parameter MODE=PM and that the
transfer
of Message Waiting Indication messages is enabled via Temporary Signaling Connections
in all
tie trunk circuits by means of the TSCS parameter in the AMO COT.
