Troubleshooting Solutions

This section describes solutions to some most commonly occurring problems.

Why is my display blank?

Ensure that power is being provided to your phone. If your network does not provide inline power over Ethernet, you can obtain an additional accessory, the Aastra PoE (Power over Ethernet) inline power supply, to provide power over Ethernet locally to your phone. See the section “Connecting to the Network and to Power” in the Aastra 57i Installation Guide for details.

Why is my speakerphone not working?

If you press the button and the speaker light flashes and you do not

hear dial tone through the speaker phone, the Set Audio option in the

phone’s Options list has been set up for headset use. Press a second

time and if the light goes out, the phone has been set up to be used only with a headset or handset. If the light stays on steady and you hear dial tone, the phone has been set up so that you can alternate between the

speakerphone and the headset by pressing . See the section

“Customizing your phone” in the 57i Installation Guide for instructions on how to change the Set Audio option.

Why can’t I get a dial tone?

Check for any loose connections and that the phone has been installed properly. For installation instructions, please refer to the “Installation and Setup” section in the Aastra 57i Installation Guide provided with your phone.

Why doesn’t my phone ring?

Check the ring volume on your phone. It may be turned down or turned off. To adjust the ringer volume setting, press the volume button when the phone is on-hook and idle. For more information, refer to the “Adjusting Volume section” in the Aastra 57i Installation Guide provided with your phone.

Why is the light not coming on with a new Voice Mail Message?

Your phone system or service provider must provide “Visual” Message Waiting service for this function to work. Check with your system administrator for more information.

Why is my handset not working?

Check to ensure that the handset cord is fully connected to both the phone and handset. See the section “Connecting a Handset or Headset” in the Aastra 57i Installation Guide for information.
