What is the CID service


The Calling Identity Delivery (CID) service or the Calling Line Identification Presentation (CLIP) service enables the AR router to send the calling party's number and call time to the called party and the calling party's number and call time displayed on the terminal device. This service requires phones supporting CID or calling number identifier between a common phone and a user line. The phones supporting CID can save numbers from multiple groups of incoming calls and provide number query and callback.

What is the meaning of Secretary Service
The secretary feature allows a secretary to manually filter calls made to a manager. Calls made to a manager are first forwarded to a secretary.
