LS-ID Delay Option
Caller ID information is sent from the central office during the first silent interval of ringing. Because it is possible to answer a call before this information arrives, you can turn on the LS-ID Delay option, which suppresses ringing until the Caller ID information arrives. This option can be programmed for each line. The factory setting is off.
On telephones with Personal Lines, the green LED next to the Personal Line button flashes when a call arrives on the line. The red LED lights and the telephone rings after a 6-second delay or when Caller ID information arrives, whichever occurs first. Telephones without Personal Lines do not receive the call until after the 6-second delay or when Caller ID information arrives.

The caller may hear one or two extra bursts of ringback if LS-ID Delay is programmed, while the person receiving the call has not yet heard a ring. |
When the option is programmed on a two-way trunk, the system does not seize a trunk from the pool for an outgoing call while that trunk is receiving an incoming call.
The difference between LS-ID Delay and Delay Ring is that Delay Ring provides a fixed delay for all calls that arrive on the button programmed for Delay Ring. LS-ID Delay affects calls that are received on lines connected to an 800 GS/LS-ID, 408 GS/LS-ID-MLX module, or 412 LS-ID-TDL module. LS-ID Delay causes a one-ring delay at every extension throughout the system on incoming calls to 800 GS/LS-ID, 408 GS/LS-ID-MLX, or 412 LS-ID-TDL modules. The call is delayed only until Caller ID information is received from the central office (on loop-start lines).
