Hello to All

We encountered problem regarding to our Yealink CP960.
Firmware Version 73.83.0.30
Hardware Version 73.0.0.9.0.0.0

When connecting via Bluetooth from laptop (Windows10) in Skype,Zoom, etc the CP960 speakerphone has a very poor sound. Laptop and CP960 in full volume but still the sound is so poor. We also update the firmware from 73.80.0.35 to 73.83.0.50. Additional when Mac unit connects to CP960 the sound is so clear and loud so there is no problem when it comes to Bluetooth connection.

We tried to connect the Laptop (Windows10) via usb device and the sound is clear and loud. We only encountered the problem when we connecting via Bluetooth.

Hi Sir,

This is Jacky from Yealink Technical Support Team, nice to meet you.

​Could you please describe the phenomenon about "poor sound", is it small volume?

If yes, May I know does it have other problems besides the small volume?

May I know what’s the probability of this problem? Is it 100%?

In order to confirm the issue quickly, so we need some information help to judge the problem, would you please help reproduce the issue and kindly provide us trace files for further analysis as below:

a. Level 6 syslog -- Need to check what operations you did on the phone

b. PCAP trace

c. Config.bin --Need to check the configuration of the phone

you can get the guide from this link to see how to export the issue data(trace files):
