INStartCallIntent Requires Unlocking of device

I have "upgraded" from INStartAudioCallIntent to INStartCallIntent because of deprecation warnings about INStartAudioCallIntent

However with INStartCallIntent when it proceeds to make the VoIP call I need to UNLOCK the device.

This defeats the purpose of using Siri where you may be driving and do not want to touch the iPhone in order to make a call

Is there anyway this can be avoided? Is there a Property List Key or Phone Setting to allow the call to proceed without unlocking?

With INStartAudioCallIntent I did not need to unlock the device so this is a step backwards for users.
