Redirection option from an IVR with ring Group or contact center options

[jmgvil]

Quick question,
What happens, when a customer's internet is down, and he has to redirect a ring group, or contact center to a external number from an IVR?
I know it's possible with an extension not registered to be redirected to a external phone number.
Is there a way around or it has to be done manually from the IVR?

There is probably a way to write a custom script to automate something like this. Otherwise, it will be manual work.
