Voice Messaging Systems
6-4 Issue 7 June 2001
 If you receive any strange messages on the voice mail system, if your
greeting has been changed, or if for any reason you suspect that your
voice mail system facilities are being used by someone else, contact the
Avaya Toll Fraud Intervention Hotline.
 Contact your central office to verify that your carrier provides “reliable
disconnect” for your host PBX or switch. “Reliable disconnect” is
sometimes referred to as a forward disconnect or disconnect supervision. It
guarantees that the central office will not return a dial tone after the called
party hangs up. If the central office does not provide reliable disconnect
and a calling party stays on the line, the central office will return a dial tone
at the conclusion of the call. This permits the caller to place another call as
if it were being placed from your company.
 Contact your voice messaging system supplier. There may be additional
measures you can take to prevent unauthorized users from transferring
through voice mail to outgoing trunks.
