# Ring Group Caller ID Behavior During Forwarding or Overflow

## Objective

To explain expected Caller ID behavior for forwarded or overflowed Ring Group calls and provide guidance on Ring Group Caller ID configuration.

## Applies To

- 8x8 Ring Groups
- Ring Group Call Forwarding
- Ring Group Overflow Routing
- 8x8 Work App
- Poly VVX Series Phones
- Caller ID Presentation

## Procedure

### Understanding Ring Group Caller ID Behavior

Ring Group Caller ID settings apply when a call initially reaches a Ring Group. Available Ring Group Caller ID display options may include:

- Caller’s name and number
- Ring Group name and caller’s number
- Ring Group name only
- Other caller ID presentation combinations

### Behavior During Ring Group Forwarding or Overflow

When a call is forwarded or overflowed from one Ring Group to another:

- the original Ring Group Caller ID information is not guaranteed to persist,
- and the receiving device may instead display:
  - the original caller information,
  - the forwarded number,
  - or the destination Ring Group details.

This is considered expected system behavior.

### Example Scenario

Initial Ring Group:

- Ring Group “010 RG one”

Destination Ring Group:

- Ring Group “009 RG two”

Configured Caller ID Setting:

- “Ring Group name and caller’s number”

Observed Result:

- receiving users only saw:
  - caller information,
  - or forwarded number,
- while the original Ring Group name (“010 RG one”) was not displayed after forwarding occurred.

### Device Behavior

This behavior is not considered device-specific and may occur across:

- 8x8 Work App
- Poly VVX phones
- other supported endpoint devices

The behavior is related to Ring Group forwarding/overflow logic rather than endpoint limitations.

### **Additional Information**

- Ring Group Caller ID formatting applies primarily to the Ring Group currently handling the call.
- Once a call is forwarded or overflowed to another Ring Group, the original Ring Group identity may no longer be preserved in the displayed Caller ID information.
- If a specific identifier is required on forwarded calls, configure the Caller ID presentation settings on the destination/receiving Ring Group rather than relying on the originating Ring Group settings.
- This behavior does not indicate a backend fault or misconfiguration.
