Learn more about VoIP:

Yes, you can use your existing business phone numbers through the process known as porting.

VoIP works with any phone number you own, including local numbers, cell phones, and toll-free phone numbers. We’ll even provide you with a temporary number with your caller ID as you transition.

Follow our advice to learn how to move your phone numbers from your existing service provider. Nextiva includes free porting with every account.

Setting up a phone system for businesses is easy. After you sign up, you can begin calling with an app you download to your computer or cell phone. From there, you can customize calling features, such as call forwarding and auto attendants, from a simple online portal.

VoIP works perfectly on almost any high-speed internet connection like cable, DSL, and fiber. You can complete a free VoIP speed test to confirm you have enough bandwidth.

If you purchase VoIP phones from Nextiva, all you need to do is plug them in. You can even use old telephones with a VoIP adapter. No technical skills are needed to enjoy your VoIP phone system.

VoIP completes phone calls using the internet instead of using the analog telephone system. The biggest difference is that you can work anywhere without running wires or expensive hardware.

A VoIP phone system offers built-in functionality such as a mobile app, video conferencing, and voicemail-to-email delivery, and more. You can also get a complimentary toll-free number as well.

Today’s VoIP solutions don’t require any bulky equipment, PBX hardware, or technical training.

Read more about the advantages VoIP has over traditional landlines.

Yes. Unlike landlines, you can complete phone calls using your Wi-Fi router. Voice over Internet Protocol (Voice over IP) has error-checking into the core of every data packet. VoIP works over Wi-Fi on all your mobile devices like your laptop, tablet, or smartphone. You can take business phone calls anywhere.

We recommend using a wired Ethernet connection, but you can certainly work remotely using just a wireless internet connection.

To use Voice over IP, you need to have a phone capable of Voice over Internet Protocol (VoIP).

These phones come in two varieties:

  • Desk phones: These IP phones resemble your typical office phone, but they function over your internet service. Traditional phone lines aren’t used but an Ethernet cable is connected to your switch or router.
  • Softphones: You can download a business phone app to your iOS or Android mobile phone. There’s no setup required. Download the app, sign in, and begin placing and receiving incoming calls on your phone. With cloud-based call routing, your desk and mobile phone can ring simultaneously.

Nextiva offers price plans designed to meet the needs of today’s businesses. Choose a monthly plan with no commitment. Maximize your savings with a contract term of 12, 24, or 36 months.

Every business phone plan includes unlimited nationwide calling and professional calling features (auto attendant, on-hold music, call forwarding, and more) enjoyed by small businesses and enterprises.
