We have registered the device on Cisco Call Manager but are unable to register the device’s Nightringer using the device’s MAC address. How do I configure two extensions on Call Manager for the device?


Create a second directory number and user for the Nightringer extension. You may need to fudge a digit of the MAC Address so that Call Manager allows you to associate it to the new user.

Be sure this MAC address does not match any other Guardian devices on your network.
