If you can provide a script, during setup, we can arrange to have your greetings recorded. This is part of our migration support and is a complimentary service. Once you are migrated, you will have the option of maintaining / replacing your greetings as needed (no tech skills required - as simple as recording a voicemail greeting!).
Alternatively you could ask us to involve one of our team of professional voice actors.
