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 Mitel PoE (Power over Ethernet) inline power supply, to provide
power over Ethernet locally to your phone. See the Connecting to the Network and to Power section in the
Mitel 6915 Installation Guide for details.
14.1 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, the Audio Mode option in the phone 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 a dial tone, the phone has been set up so that you can alternate between the
speakerphone and the headset by pressing . See “Audio Mode” for instructions on how to change the
Audio Mode option.
14.2 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 Mitel 6915 Installation Guide.
14.3 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.
