Check the connection from the handset to the router/switch, to ensure it's receiving a signal.

•

Swap out Cat 5 cables and check ports, as well as connections on all wires.

Plug the handset into a different port that you know definitely works.

•

If none of these work, call our support team.

The handset displays an "SOS Recovery Mode" message

This means the handset has become corrupted whilst updating its firmware. This could be due to a

power issue, for example, which has caused the service to pick up a bug and disconnect. It's a

common issue on Cisco devices and a fix exists at https://supportforums.cisco.com/docs/DOC-

10011.

If you can't follow this guide or encounter more problems, call our support team. They'll either offer

more advice or send out a replacement device.

The handset has an obvious defect or physical fault

If one of your handsets has been physically damaged, for example it has a broken screen or

receiver, call our support team. They'll ask for more details and send you out a replacement if the

phone is still within its warranty period.
