Registering the Attendant PC software

Question: The PC Attendant is stuck in Position Busy, although it has been working fine since installation about a month ago. The handset and headset are properly installed and it's not in Night Mode, so why won't the console unbusy?

Answer: Nortel requires this product to be registered within 30 days following installation. Please verify that the software has been registered. If not, you will need to obtain a registration number from the vendor.

Problem: There is no more support for the PC Attendant Console!

Solution: If you can find your registration number, enter it as described below. Otherwise:

Attendant PC v1.2.411 will run on Windows 10, but check the COM port number (see below).

Serial COM port:

PC Attendant requires a serial port (for connecting a 2250 or PCCIU), but it only supports COM1-4. The PC's serial port (or USB-to-Serial adapter port) may need to be manually assigned a port (1-4) in the devices 'Advanced Settings'. This should also ensure that the port doesn't change after a reboot.

  1. Open Device Manager (shown right →)
  2. Right-click the serial device, click Properties
  3. In the Port Settings tab, click Advanced
  4. Set a COM Port Number from the list
  5. Select this port in PC Attendant:

The following information is taken from the NTP: PC Attendant installation (553-3001-320), page 179.


The Attendant PC software has now been installed, however this software will expire in 30 days unless it is made permanent by the following registration process.
