Endless ringing calling to Chrome 56+

[Ivansss]

When calling from the app to another user, that is using Chrome 56+, the iOS app keeps ringing and no conversation can take place.

On the other hand, the iOS app can be called by that (Chrome) user. Answering the phone by the iOS client works, the conversation can start.

Occur both with video and audio only calls.

When logging on the Chrome side I see 'Received STUN request with bad M-I' in the log. Could be an issue with the removal of the 'Google-Ice' option in chrome, the app sends this in the offer but chrome no longer supports this.
