When in a Chalk call and a cellular call comes in the Chalk call is interrupted. Even if the IOS device is set to Do Not Disturb the Chalk call is still interrupted.
Is there a way to ensure the Chalk call is not interrupted?
There is no setting available at this time to block incoming calls. Incoming call notifications will be seen on the screen and it is up to the user to pick up or decline the call.
Thanks for providing additional information on the current situation. I'll relay this to the Product Team for consideration in future releases.
