Last Number Redial


Last Number Redial allows an extension user to quickly redial the last outside number dialed. For example, a user may quickly recall a busy or unanswered number without manually dialing the digits. Last Number Redial saves in system memory the last 20 digits a user dials. The number can be any combination of digits 0-9, # and *. The system remembers the digits regardless of whether the call was answered, unanswered or busy. The system normally uses the same line as for the initial call. However, if that line is busy and is part of a Line Group, Last Number Redial will automatically select the next line in the group. The user can also preselect a specific line if desired.

Enhanced Last Number Redial

If enabled, Enhanced Last Number Redial allows the extension user to select from the last 5 outside numbers dialed. When the user places an outside call, the number dialed is stored in the Enhanced Last Number Redial buffer. This buffer saves the 5 most recent numbers (including Speed Dial calls), with the most recent call at the top of the buffer and the oldest number at the bottom of the buffer. Old calls get pushed off the bottom of the buffer to make room for new calls at the top. If a user dials a number that is already stored in the buffer, the system inserts the number at the top of the buffer and deletes the duplicate entry.

The numbers stored in the Enhanced Last Number Redial buffer are retained if the system resets or is powered down.

Automatic Hyphenation in the Enhanced Last Number Redial Display

The system will automatically insert hyphens in the Enhanced Last Number Redial display for the types of calls listed below. All other calls are displayed without hyphens.
  • NNX + xxxx calls (e.g., 926-5400)
  • NPA + NNX + xxxx calls (e.g., 203-926-5400)
  • 1 + NPA + NNX + xxxx calls (e.g., 1-203-926-5400)

If the call is placed on a PBX line, and the PBX access code is dialed, the display shows the PBX access code, a space, followed by the dialed number using the same hyphenation as shown above (e.g., 9 1-203-926-5400). If the PBX access code is not dialed, the number is displayed without hyphens.
