Dialing directory for separate systems?

We have a customer with two locations and two Freepbx systems. All calls come into the Home office. The customer wants a IVR option where the caller can access a Directory of the extensions by name for “Both” locations, so they can dial an extension in either location. Is there a way to do this?

Thanks

Yes the company directory allows manually adding custom entries.

Thanks Tony. I will set up a couple of systems and see how it works.
