👉 Dialpad tip:
You’ll also sometimes hear people talk about DID in terms “Direct Dial-In” (DDI) and “direct-dial numbers.” There’s also Direct Outward Dialing (DOD), which is a similar service that’s used for outbound calls from your business phone system. This is used so you don’t need to press a number before dialing out or to connect with an operator.

👉 Did you know?
Dialpad works across Windows, Mac, iOS, and Android devices. It’s also browser-based, which means you can make or take calls via your virtual phone number right in a web browser—no need to download the app.



👉 Dialpad tip:
When you’re adding numbers, try to add local numbers—your clients or prospects may not see the area code for the phone number if their call is automatically forwarded, but you don’t want them to get a surprise long-distance charge later because you set up an international call forwarding number.
