No dial tone

[Jordan131]

We use yealink phones and have plantronics CO54 headsets. I have a set that will not produce a dialtone. The set appears to connect to the phone. The phone acknowledges the headset and acts like it can take or make a call using the earpiece, however there is no dial tone, and I sound very faint to the person on the other end of the call.

I have tried reconnecting the headset by pressing the connection button on the top of the base. I have tried rebooting the headset and phone. I have tried removing the battery from the head set, unplugging the base from power and the phone, and unplugging everything on the phone. I still have the same results: the headset and phone appear connected, but I cannot hear a dialtone nor can the caller hear me clearly. 

The Connection is set to A, and I have turned the volume for both the earpiece and the microphone up and down.

What else can I try?

Hi @Jordan131, Welcome to Poly HP Support Community.  
 

I’m sorry to hear about the issues you’re experiencing with your headset. I understand how important it is to have your headset functioning properly. Here are some troubleshooting steps you can try:

1. Check the Audio Settings: Please ensure that the audio settings on your Yealink phone are configured correctly. Sometimes, the phone may prioritize the built-in speaker or microphone over the headset.

2. Change Connection Settings: If your headset has multiple connection options (like A/B), consider switching to the alternate connection to see if that resolves the issue.

3. Test on Another Phone: If possible, connect your headset to another Yealink phone. This will help determine whether the issue lies with the headset or the original phone.

4. Check Connections and Cables: Ensure that all cables (power, phone line, etc.) are securely connected and free from damage.

5. Microphone Placement: Make sure the microphone on the headset is positioned correctly. If it’s too far from your mouth, it can impact audio clarity.
