To resolve:
Check for any loose connections and that the phone has been installed properly. For the Installation instructions, refer to the phone installation
section.
Check whether dial tone is present on one of the audio modes.
Switch between the Handset, Headset (if you have) or Hands-Free Speakerphone to check whether dial tone is present for one of the audio
modes.
If the dial tone exists on another audio mode, connect a different handset or headset to isolate the problem.
