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
key 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,
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 9143i 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 key when the phone is on-hook and idle. For more information, refer to the “
Adjusting Volume section
” in
the
Aastra 9143i 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 9143i Installation Guide
for information.
