How to make the phone recognize the le audio device as an audio device without call function

[ZombietoC]

I'm developing a speaker with both Classic Bluetooth and LE Audio functionality, which does not support calls.

We have removed the Hands Free Profile, Call Control Profile, and the Conversation source context. After connecting to a Samsung S23 phone through Classic Bluetooth, it shows "Connected for audio," but when switching the device to LE Audio, it still shows "Connected for calls and audio."

Although calls are not routed through LE Audio during a conversation but rather through the phone's microphone and speaker, the Bluetooth interface message is confusing. I would like to ask, for LE Audio devices, how does the phone determine whether the device supports calls?

Whoa, I like your style. Make it your way 👏

I think this level of detail probably resides on the Google side of the fence
