Forward Unanswered Call From Queue to External RingCentral Number in Different Account

I am looking to have a call forwarded to our corporate office (is also RingCentral, but different account) if someone at a specific location does not answer a call in a queue after a certain amount of rings, or time.

As a secondary feature, to have the ability to have whisper text play when the call is answered at the corporate office, for example "Pennsylvanaia Reservations" before the caller is connected would be great.
