AMIS Networking
AMIS Networking (the DEFINITY AUDIX System, the AUDIX Voice Mail System
R1V6 and later, and the Avaya I
NTUITY System) allows voice messages to be
sent to and received from subscribers on other vendors’ voice messaging
systems. This service is based on the Audio Message Interchange Specification.
This feature allows calls to be placed to off-premises voice messaging systems.
Message Delivery
AMIS Networking (the DEFINITY AUDIX System, the AUDIX Voice Mail System
R1V6 and later, and the Avaya I
NTUITY System) offers a message delivery
service that delivers voice messages to any designated telephone number. As in
the case of outcalling, this feature allows calls to be placed to destinations that are
off-premises.
Security Measures
Where indicated, the security measures in this section apply to specific releases
of both the AUDIX Voice Mail System and the switch.
Disallow Outside Calls
!
CAUTION:
If TAC calls are permitted, they may be accepted as a valid extension
number. Even with Enhanced Call Transfer activated, toll hackers may be
able to enter a TAC to get an outside line if 3-digit station numbers and
3-digit TACs are used.
The Enhanced Call Transfer feature is available on a voice mail system integrated
with the System 85 R2V4, System 75 R1V3, Issue 2.0, and later software
releases, DEFINITY Generic 1, Issue 5.0, and later software releases, DEFINITY
Generic 2, DEFINITY Generic 3, and DEFINITY ECS. If you have an earlier
release but want the added security offered by Enhanced Call Transfer, consider
upgrading to the required PBX software. Use the following procedures to activate
Enhanced Call Transfer.
NOTE:
For System 75 R1V3, Issue 2.2 is required if you are using 3-digit extension
numbers.
