VoIP technology—and cloud-based virtual phone systems in general—are transforming business communications.

Keep reading to see how to get a VoIP number in just a few minutes with Dialpad and how to use it.

What is a VoIP number?

A VoIP (or Voice over Internet Protocol) number is basically a virtual phone number. You use it like a regular phone number, except VoIP numbers facilitate phone calls using an Internet connection.

That means you can make VoIP calls from any Internet-enabled device (cell phone, computer, softphone, desk phone, you name it). The number itself also isn’t tied to a particular device or even a specific geographic location. (More on fixed and non-fixed VoIP here.)

How does a VoIP phone number work?

If you’re getting a number for your business, first you’ll need to get a business VoIP phone number, which you’ll get set up with when you sign up to a VoIP service like Dialpad.

From there, you can make outbound calls and take incoming calls through your Internet or VoIP network instead of the public switched telephone network, or PSTN. (That’s basically the traditional phone network using phone lines)

To make a VoIP call, the only things you’ll need are a reliable Internet connection and a phone or computer that's logged into your VoIP account. For example, here’s a look at a VoIP call in progress in Dialpad’s desktop app:

Set up in minutes

It takes a few minutes to get a local VoIP number with Dialpad. Just sign up for a free trial and you’ll get a VoIP number during the signup process. If you end up liking Dialpad, then after the trial you can just sign up for one of the Dialpad Talk plans (starting at $20 per user per month) to keep that number and continue using Dialpad—this comes with things like video conferencing, call recording, custom voicemail greetings, and unlimited calling within your local country, US, and Canada, all for free by the way.

Excellent call quality

Latency, jitter, and packet loss are all common issues that can affect VoIP call quality, but Dialpad’s global voice network is designed to ensure that all phone calls (even if you’re conferencing) are crystal clear. HD audio, if you will. If you are worried about connectivity or your Internet service, T-Mobile does have a package that gives you a lightning-fast 5G network and Dialpad’s unified communications platform.

SMS and instant messaging

Sometimes you just need to pass on some info or ask a quick question, but you don’t want to have a video meeting or make a phone call. With Dialpad you can send messages via SMS, MMS, or group chat right from the Dialpad desktop or mobile app. These messages can be internal or external to customers and clients. Dialpad also automatically detects whether your recipient is also using the app—if not, your message will be converted into an SMS so they can view it like a text!

Custom caller ID

With Dialpad, you can also choose what your caller ID shows when you’re calling someone. This is especially useful if you’re using your personal cell phone for work, because this hides your personal phone number and shows whichever business number is best for the call. For example, you can choose your main company number, a departmental number, or just a personal business number for your caller ID.

Call forwarding

Dialpad also helps you easily forward calls to an external phone number or device (even one that’s not connected to Dialpad). You can can send incoming calls to up to five different external mobile or landline numbers.

Different types of virtual numbers


Local numbers are numbers that start with an area code specific to a particular region, city, or state. Local numbers are generally best for regionally-based or small businesses with a very localized customer base.

Having a local business number means that your customers or potential customers won’t get hit with long-distance call charges (and makes them more comfortable with proactively calling you).


Toll-free numbers are telephone numbers that start with a three-digit code like 800. This code allows callers to dial without incurring any charge, since the call charge falls on the receiver (in this case, your business) instead.

Businesses typically use toll-free numbers for increased credibility and to make sure their customers or prospects can call them for free (maybe as part of a marketing campaign).


A vanity number is a custom telephone number that’s unique to your business. Vanity numbers are a great way to differentiate yourself from competitors and make your business more memorable.

For example, a T-shirt business might choose a vanity number like 1-800 T-SHIRTS.

The big differences between VoIP numbers and landline


VoIP services tend to be significantly cheaper than their landline counterparts. One big reason is because VoIP needs only Wi-Fi or an Internet connection—no physical phone system hardware.

That means you can save quite a bit on costly implementations and maintenance of landline telephone networks.

With VoIP phone systems and numbers, you typically just pay a fixed monthly rate to a VoIP service provider. There’s no expensive upfront costs, and in return, you’ll enjoy unlimited scalability and a ton of functionality like auto-attendants, call routing, messaging, call recording, and more (Dialpad’s least expensive VoIP plan comes with all of these included):

International/distance calling

Landline telephones aren’t ideal if your business needs to make regular international or long-distance calls. Why? Because it’s going to be really expensive.

With VoIP, businesses that have lots of long-distance calls overseas tend to save money in the long run because the rates with VoIP are generally much lower.
