Ring Groups
Ring Groups determine how trunks ring extensions. Generally, trunks ring extensions
only if Ring Group programming allows. For example, to make a trunk ring an
extension:

Assign the trunk and the extension to the same Ring Group.

In the extension Ring Group programming, assign ringing for the trunk.
Any number of extensions and trunks can be in a specific group.
The system allows:

Ring Groups = 1~100

In-Skin Voice Mail = 102

Centralized Voice Mail = 103
If an extension has a line key for the trunk, Ring Group calls ring the line key. If the
extension does not have a line key, the trunk rings the line appearance key. If an
extension has a key for a trunk that is not in its ring group, the trunk follows Access
Map programming.
Ringdown Extension, Internal/External
With a Ringdown Extension, a user can call another extension, outside number, or
Speed Dialing number by lifting the handset. The call automatically goes
through – there is no need for the user to dial digits or press additional keys.
Ringdown Extensions are frequently used for lobby telephones, where the caller lifts
the handset to get the information desk or off-site Reservation Desk.
After the Ringdown Extension user lifts the handset, ringdown occurs after a
programmable interval. Depending on the setting of this interval, the extension user
may be able to place other calls before the ringdown goes through.
Room Monitor
Room Monitor lets an extension user listen to the sounds in a co-worker’s area. For
example, the receptionist could listen for sounds in the warehouse when it is left
unattended. To use Room Monitor, the initiating extension
and the receiving
extension must activate it.
When using multiline terminals for monitoring, an extension user can only Monitor one
extension at a time. Many extensions can Monitor the same extension at the same
time. However, only one single line telephone can monitor another single line
telephone at a time.
