I am not able to reproduce this bug.
@Madar, on which WebRTC call site were you able to reproduce?

[Madara Freimane]

Hi, Youenn!

This is only with iPhone 14 models.
I see that camera and audio are paused while Siri is activated on other iPhone models, but I do no see it with iPhone 14 models, I tried using https://webrtc.github.io/samples/src/content/devices/input-output/.

Bug is reproducible on:
- iPhone 14 (iOS 16.6, build: 20G75)
- iPhone 14 Pro (iOS 17.0 Public Beta 4, build: 21A5319a)

Bug is not reproducible on:
- iPhone 11 Pro Max (iOS 17.0 Developer Beta 6, build: 21A5319a)

Observed the same behaviour on iPhone 15 models.

Tested device and browser:
