The PIN (Personal Identification Number) code prevents unauthorized personnel from making calls. To protect privileged access to the telephone lines, only authorized users are entrusted with the PIN codes for daily operations. Some PBX (Private Branch eXchange) systems require that a PIN code be entered when dialing a number to make a call or send a document by fax. Depending on the requirements of the PBX system, the PIN code may be entered either before the number as a prefix, or after the number as a suffix.
If your PBX requires a PIN Code to get an outside line, your machine can be set to prompt the user to enter the PIN Code before dialing.
