Caller ID Overview

This topic describes what is caller ID, differences between all the types of caller ID defined in Yeastar P-Series Software Edition.

What is Caller ID?

Caller ID is a telephone service that transmits a caller's telephone number and name to the called party's device when a call is established.

Caller ID types

Yeastar P-Series Software Edition supports the following types of Caller ID:

Outbound caller ID
Outbound caller ID is the phone number that will be displayed on the called party's phone when an extension user makes an outbound call. Each trunk has a main number, the number appears when an outbound call is received by a recipient.
To customize the outbound caller ID, you need to purchase the service from the trunk provider, and set the custom outbound caller ID on the PBX. In Yeastar P-Series Software Edition, you can configure outbound caller ID based on the following features:
  • Emergency Numbers
  • Outbound Route
  • Trunk
  • Extension
For more information, see Customize Outbound Caller IDs.
Inbound caller ID
Inbound caller ID is an external user's phone number that will be displayed on an extension user's phone when the external user calls in Yeastar P-Series Software Edition.
Inbound Caller IDs can be reformatted before they are sent to the destination users. For more information, see Reformat Inbound Caller ID based on a Trunk.

Priority of outbound caller ID

When an extension user makes an outbound call, the system first identifies if the call is an emergency call, then sends an outbound caller ID by the following priority (from the highest to the lowest).

  1. Extensions' emergency outbound caller ID
  2. Trunk's emergency outbound caller ID
  3. Outbound Route caller ID
  4. Trunk's outbound caller IDs that are associated with extension users
  5. Trunk's general outbound caller ID
  6. Trunk's default phone number that is provided by the carrier
  7. Extension's caller ID
