Description

customer’s premises. Basic Centrex features often include the following:

■ Drop
■ Hold
■ Recall
■ Call Forwarding
■ Call Waiting
■ Call Pickup
■ Group Pickup
■ Automatic Callback
Additional features such as Speed Dialing and Night Service may also be
available from some telephone companies. Centrex features other than those
specifically discussed in this section are accessed by sending a switchhook
flash and dialing the appropriate feature code, These codes are not intercepted
or interpreted by the communications system.
