Understanding Ring Types
The Ring Types determine how different types of calls rings extensions. Each Ring Type sounds unique
because it uses one of the 10 available ring tones. The first four Ring Types are assigned by default (see the
table below). The last two (B and C) are unassigned by default but you can assign on your phone using
Extension Override and Key Ring Override.
When Multiple Calls Ring an Extension
When multiple calls with different priorities are ringing an extension, the system prioritizes ringing accord-
ing to the list below. All LEDs will flash as appropriate for the type of call, but the telephone will ring only
for the highest priority call.
1. INTERCOM Key
2. Line Key (from lowest to highest)
3. Loop Key (from lowest to highest)
