Troubleshooting Solutions
Why is my display blank?
Ensure that power is being provided to your phone. Make sure your phone
is plugged into a power source.
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 53i 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 53i 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 53i 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.
How do I find the IP address of my phone?
Instructions on where to find the IP address of your phone can be found in
