DS1000 Ring Assignments and Voice Mail Ports
In DS1000 software version 02.01.07 and higher, the system automatically dis-
ables the 1805 - Ring Assignments programming for all single line ports assigned
as Voice Mail ports in 1802 - Voice Mail Port. To have Voice Mail answer an out-
side call, the trunk should be a Direct Inward Line (i.e., directly terminated) to the
Voice Mail master number.
Conditions
● If an extension has a flashing MW lamp and the system resets or power fails,
the MW key continues to flash after the system restarts.
● When using ASTU PCBs, the number of Voice Mail ports you can install is
limited by available system DTMF receivers.
● When the system rings an idle Voice Mail port, it will continue to ring the port
until answered. The call will not cycle to a another member of the UCD Group
(as it will for voice calls).
● In software versions 02.03.03 and higher, the system will never send a loop
supervision disconnect signal (i.e., drop pulse) to Voice Mail ports.
Default Setting
Voice Mail not installed.
