Last Number Redial (LNR)
The last number dialed is stored (up to 32 digits) in the station's Last Number Redial (LNR)
buffer. The user may request the system redial the last dialed number without the need to dial
the number.
Digital Phone users can display stored LNR numbers on the phone LCD using the [REDIAL] or
[SPEED] button and [VOL UP]/[VOL DOWN] buttons, to select the number to dial from the list
and place a call.
CONDITIONS
- For Digital Phones with LCD display, the LNR redial buffer will store duplicate
numbers unless dialed consecutively.
- When the CO/IP line used for the original call is busy, the System will select an idle
line from the same CO/IP line Group to place the call.
- Using LNR will cancel Automatic Called Number Redial if active.
- The LNR is stored in volatile memory, so it is not protected in case of a power failure
- Manually dialing a Flash during an outgoing call will cause only those digits dialed
after the Flash to be stored in the LNR buffer.
- LNR applies to both CO and VoIP calls.
