1. Make sure your headset is compatible with your phone.

2. Make sure that the cables are properly connected.


• Check if the headset cord is fully connected to the headset jack on the phone. 

• Check if the headset volume is adjusted to an appropriate level. 

 

3. Initiate a test call using the headset. 


Is the headset audio working? If the headset audio is working, you may be experiencing audio issues related to your network. Go to Call Quality - VoIP QoS Frequently Asked Questions to learn more. If not, continue to the next step. 

 

4. Try another headset.


Isolate the issue between the phone and the original headset. Use the spare headset to initiate a test call. If the headset audio is working on the spare headset, then the original headset needs to be replaced. If you are unable to hear anything using the spare headset, the phone may be defective and needs to be replaced.
