## Register Recall In PSTN

## Definition/Use

Inquiry, Refer back and Conference can be established on a system telephone without using a second external line.

## Operation

By pressing the programmable R-key on a system telephone, the following features are available:

- Inquiry on the same external line
- Refer back
- Conference

These features can be used on the same line, which is a great advantage as compared to the PBX functions, where always two external lines will be occupied for achieving the same functionality.

During suffix dialling, a TCD check that differs from the normal TCD check is performed.

## Capacity/Limitations

The register recall can be done from all system telephones with programmable keys.
