Hi,
We've noticed that this issue occurs more frequently after upgrading to iOS 18.4.1 and can result in one-way audio.
Our app uses CallKit with WebRTC to establish VoIP connections.
However, on iOS 18.4.1, CallKit no longer triggers:
func provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession)
We're currently comparing the occurrence rate across different iOS versions to better understand the impact.
Could you please help analyze the root cause of this issue?
Just to provide an update: Our metrics show that iOS 18.6 is still maintaining a high one-way ratio.
Is this with or with the workaround I recommended?
BTW, since you've raised this issue to your team, is it possible to share the plan or indicate in which version the issue is expected to be resolved?
No, I'm afraid I can't talk about our release schedule.

Hi @DTS Engineer

No, we may try your recommended workaround solution. However, it won't be implemented quickly before we release to production.
