AMIS networking
AMIS networking (available on 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 (available on 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, DEFINITY ECS, MultiVantage™ Software, and
Communication Manager. If you have an earlier release but want the added
security offered by the Enhanced Call Transfer feature, consider upgrading to the
required PBX software.
Use the following procedures to activate the Enhanced Call Transfer feature.
NOTE:
For System 75 R1V3, Issue 2.2 is required if you are using 3-digit extension
numbers.
