Hi Sorry if this has been answered before, but I cannot get the microphone to work during a HF call.
I have a BC127 running Melody 6.0.46, connecting to an iPhone running 10.3.3. If I call the iPhone the ringing is heard via the BC127, I can answer the call on the BC127 and I can hear the audio from the remote phone, but the remote phone cannot hear audio from the microphone connected to the BC127.
We have checked and the signal from the microphone is present at the correct (left) input, but nothing is sent via the BC127.
I cannot find any document that says “this is what you need to configure to get a 2 way HFP call working”
Any help would be greatly appreciated.
Couple of things,
- Defaults should be enough to route a call through successfully.
- I would first upgrade to the latest greatest version 6.1.5 firmware matter of good practice.
- Make sure you are using the audio out plug on the disc kit and not the stereo out one.
- I have just made a call to my iPhone 4 and it all connected through correctly (although I did have to route the audio to BT on the iPhone) as per the below. I have shown the config on my unit for you to reference.

Thanks for the response. It is good to know that there is nothing special I need to do to make this work. I will go through your settings and compare them with mine and also try upgrading to the latest version.
