iOS 11 Beta 4 Call connects but no sound

[d5aqoëp]

Call connects but there is no sound from ear speaker or even after putting it on speaker mode. Call connect timer starts running and the opposite person tells me that they could hear my voice.

2nd time, the call usually connects with proper sound.

Anyone with this problem?

I’ve had that happen a few times when answering a call.
