From the Device list, select the device you want to add to your device inventory.
In the MAC Address field, type the 12-digit MAC address for the device being added. We recommend you type the address from the back of the phone, rather than the package for the phone. Sometimes this packaging can be incorrect.
After the MAC address(es) has been added, return to the Device list and select it from the list.
To figure out why a phone isn't working, the first step you can take is to view a list of line states. This list shows which lines are connected or registered to the network.
Click on Line States from the Devices tab. A list of the phones and services built for your organization will be displayed.
Items without a MAC address are software related applications on desktops or mobile devices and will never show a "registered" state.
If your list of phones and services is long, use the search fields at the top to locate the phone in question or sort by clicking on column headings.
Click the MAC address column heading to sort by MAC address.
All phones assigned a MAC address should show a state of "registered." If they do not, continue troubleshooting.
