What Is VoIP?

VoIP, or Voice over Internet Protocol, is a technology that allows you to make phone calls using your internet connection instead of a traditional landline. VoIP phone service works by converting your voice into digital signals that travel over your broadband network, delivering crystal-clear sound and reliable call quality.

With Highline’s whole-home Wi-Fi, your VoIP service is backed by a strong, secure connection in every corner of your house. Our mesh Wi-Fi ensures whether you're using a cordless handset, smart speaker or your phone app, you stay connected seamlessly. 

Benefits of Using a VoIP Phone Service

Are you considering VoIP versus traditional landline services, wondering which one is right for you? There are many benefits of VoIP, including:

• Lower costs: VoIP uses your existing internet connection, so you can reduce monthly bills in many cases by getting VoIP instead of a landline. You also pay less for long-distance calls with a VoIP phone service.
• Flexibility: With VoIP, you can take calls from your computer, smartphone, or tablet — wherever you have internet access — with no extra lines or special equipment required. If you always need to manage your home phone while traveling, you’ll love the flexibility of VoIP.
• No latency, lag or dropped calls: When paired with Highline’s fiber internet, VoIP shines. Our customers experience smooth, uninterrupted conversations with no latency or dropped calls, even during busy evenings. And because we offer local on-site support and white glove installation, we make sure everything’s set up right the first time so you can enjoy crisp, clear audio on all calls.
• Advanced features: You can get a landline with call forwarding and other features, but VoIP offers more. Enjoy call forwarding, caller ID, voicemail to email, three-way calling, real-time app-based call controls, and more. If you run a small business, you’ll especially appreciate being able to check your voicemail from anywhere, even through your email.
• 911 security: When you get your VoIP from Highline, we make sure you’re enrolled in the 911 database. When you use your VoIP phone service to call 911 in an emergency, dispatchers can instantly see where you are, even before you say a word. 

Whether you're in Michigan’s Upper Peninsula, the mountain towns of Colorado, or the wide-open spaces of Texas, Highline is proud to connect your home or small business with innovation that includes VoIP, high-speed Wi-Fi that reaches everywhere on your property, and more. When you switch to VoIP with us, you can even keep your existing number.
