Vertical Service Activation Code Notes

•You can change default star code values for your area or region.

•Call Back: Similar to the call back service offered by the PSTN, the caller can activate this service on a busy number to recieve a call back as soon as the busy number becomes available.

b.The phone uses this call appearance to call the last called number. The retry period and expiration time are configurable.

c.While the call back service is active, the corresponding line key flashes green. The line can still be used: the call back service will pause temporarily until the call appearance is idle again. To cancel the service, the caller can pick up any line and enter *86.

d.When the call back number rings or answers, the call appearance rings like a normal incoming call. If the call back party answers the call before the caller does, the phone sends a holding tone to the call back party. If the caller picks up the call back first, the phone rings like a regular outbound call.
