Program 10 : System Configuration Setup
10-08 : Pre-Ringing Setup
Level
IN
Description
Use Program 10-08 : Pre-Ringing Setup to enable or disable pre-ringing for trunk calls. This sets
how a trunk initially rings a telephone. With pre-ringing, a burst of ringing occurs as soon as the trunk
LED flashes. The call then continues ringing with the normal ring cadence cycle. Without pre-ringing,
the call starts ringing only when the normal ring cadence cycle occurs. This may cause a ring delay,
depending on when call detection occurs in reference to the ring cycle.
