If your Aastra IP Phone displays a 'Network Disconnected' message, first ensure the cables are securely connected to both the phone and the wall jack. If the issue persists, restarting the phone may resolve the problem, especially if there have been recent changes to your phone’s network settings.

If your Aastra IP Phone speaker is not working, the Audio Mode option in the Options list may have been set up for headset use. Press the Speaker key a second time; if the lamp goes out, the phone has been set up to be used only with a headset or handset.

If your Aastra IP Phone display is blank, it could be that your network does not provide inline power over Ethernet. To resolve this, obtain an Aastra PoE (Power over Ethernet) inline power supply to provide power over Ethernet locally to your phone.
