With direct outward dialing, users are able to make outbound calls to anyone outside of their PBX by dialing the standard format for local, national, or international numbers. Under system settings you can even set a default area code to eliminate the frequent dialing of that code.
Users are able to call not only your colleagues, but clients, potential customers, and anyone outside of your direct PBX as well.
Do I need a PSTN access number to call outside of the PBX?
No. A PSTN access number is not necessary to call outside of the PBX.
Do I have to dial a number code (e.g., 9) before placing external calls?
No. Direct Outward Dialing allows users to make external calls without the need of number codes.
