System Manager’s Guide
for MERLIN LEGEND®
Communications System
To diminish the risk of toll fraud occurrences, the Transfer to Subscribers
Only? parameter on the System Parameter Administration screen is now
permanently set to yes. This setting restricts transfers to registered subscribers
only. During a transfer from within Automated Attendant, Voice Mail, or Call
Answer services, when a caller enters an extension number, it is validated
against the subscriber database of the AUDIX® Voice Power™ system. If the
extension entered is not in the subscriber database, the caller will hear “That is
not a valid extension,” and the transfer will be denied. This will prevent the caller
from having an opportunity to gain access to the outgoing facilities of the
telephone communications system.
In some cases, it is necessary to allow transfers to extension numbers that do
not have corresponding voice mailboxes. For example, there may be a need to
transfer to a fax or data extension, or there may be a subset of users who do not
need to receive voice mail, but who should be able to receive transferred calls.
In these instances, such extensions can be administered as AUDIX Voice Power
subscribers with restricted mailboxes to ensure transfers to these extensions.
Restricted mailboxes can be set up by allocating minimal mailbox space (for
example, 1 minute). Additionally, the Subscriber Switch Call Coverage option in
AUDIX Voice Power should be set to
Yes to avoid tieing up voice channels.
If voice mail is addressed to any of these restricted mailboxes, the limited
mailbox size will prevent most messages from being delivered.
NOTE:
Do not assign special-purpose subscribers (users with a mailbox but no
telephone on the switch) to extension numbers that start with the same
digit(s) as switch trunk access codes (for example, 9).
If you require assistance with the above administration, call the AT&T Support
Center at 1-800-628-2888.
