Hi,

I have in my project K165 Vantage 2 and I am using 3rd party SIP App and works fine with that model, now I am using K175 Vantage 3 but when I am installing the 3rd party App which is same installed in old model doesn't work with Bluetooth handset every time I hook off the handset only speaker works with me, I tried to disable vantage base connect and remove the permissions but still not work.

I don't have what did they do last to make it work in K165, do I want to contact the developer to update the SDK in their source code of the app, or I have to do something in 46xxxsettings file with special parameters?

Can you guide me please how to solve this issue?

Thanks for all

Reach out to the developer of the third-party SIP app and inquire about compatibility with the K175 Vantage 3 model. They may need to update their app or provide specific instructions for the newer model.
