Deskphones – Polycom – Network Link is Down – Phone Connectivity Issue | AT&T Office@Hand
Article #11097

Polycom phones do not have a LED indicator for the network LINK status, unlike other networking devices. Therefore, link failures are indicated with the message Network Link is Down.

The message is shown on the screen and will continue to persist until the phone detects an IP address from the network where it is connected.

Resolving Network Link is Down Phone Connectivity Issue

  1. Check the physical connections.
    These include the power cables and ethernet cables. Ensure that the cables are snugly fit into the correct ports on the Polycom Phone and on the router. Also, check if the wires are not broken on both ends.

    • On the Router / modem / switch, the Ethernet cable should be connected to the Ethernet ports.
    • On the Polycom phone, the Ethernet cable should be connected to the LAN port.
  2. Restart your network devices
    Unplug the power cable from your network devices (modem, router, switch, and phone), and then plug the power back in the proper order, starting from the device closest to the wall (modem > router > switch > phone).
