Teams Auto Attendant Unable to redirect to outside numbers

[RDP-work]

I have an auto-attendant I'm testing. I can dial in to it and connect OK and get the menu. I can reach the operator number. When I try to reach a person configured as a "Re-direct to outside number", the number dials once and then drops back to operator with a "Sorry I couldn't Reach...." message.

The numbers I'm using are NZ based (so formatted +64....) and the AA is set to UK English (no NZ variant available)

The Resource account in use has a Microsoft 365 Phone System - Virtual User licence and (as a test) a Microsoft 365 Domestic calling plan.

The "Operator" is a common area phone (I imagine it as a receptionist phone) and that, with the same calling plan but also a common area phone licence and phone system licence, is able to call cell-phones in NZ and can transfer to cell-phones (which was another battle in itself) so I know calling to cell-phones  can work.

Any ideas why it might be failing to call outside numbers?
