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 pre-programmed 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.
