I suggest you should report it to the developers of PulseAudio since that's the component that implements Bluetooth audio:
https://gitlab.freedesktop.org/groups/pulseaudio/-/issues Less likely, you might need to report it to the BlueZ Bluetooth developers: https://bugzilla.kernel.org/enter_bug.cgi?product=Drivers&component=Bluetooth When done, please tell us the new issue ID here. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1553669 Title: Annoying "call from" message when connecting Bose devices Status in bluez package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: I have a bluetooth Bose OE SoundLink working on Kubuntu 15.10 but each time I initially connect to listen to an audio or video, I hear an annoying "Call from" on my headset. My headset seems to think a connection to a phone call is taking place. This is annoying because the audio will start to play and after a little while the "call from" voice talks over the audio.
