Multi-Line Phone Systems for Business

Cloud VoIP makes your business more agile

As a small business, you have unique needs. Business VoIP phone service gives you and your team greater flexibility to serve your customers and effectively grow your business, no matter where you are.

What is business VoIP?

Business VoIP is a type of phone service that allows you to make calls over the internet using voice over internet protocol (VoIP) technology. It offers more robust business phone features than residential VoIP plans do. Some of these features include call routing, call queues, recording, auto attendants, and virtual extensions. Your business VoIP provider manages and maintains your company’s cloud-based phone system and provides softphone software that allows users to make and receive calls from any device.

Seamless business phone — even when you’re not in the office

Worried about missing calls when you’re not in the office? With business VoIP phone service, free yourself from the landline and make or receive calls from virtually anywhere.

Switching to a business VoIP phone service allows you to stay agile and enhance your team’s ability to work remotely. Going beyond the limits of traditional on-premise telephony enables you to adapt to shifting customer demands and maintain business continuity in situations that take you out of the office for an extended period of time.

How to choose your business VoIP phone service

Make sure your small business VoIP provider offers services and features that meet your current and future needs. Will your VoIP provider support your business with flexible, affordable plans and a phone system that allows you to scale easily as you grow?

Port your existing number(s)

Porting phone numbers to a new provider can require expertise to ensure you don’t run into delays or issues. Look for a VoIP provider with an expert team that can help you streamline and simplify the process.

Design your phone system

Business VoIP solutions offer a number of customizable features. You can set up auto attendants, call queues, recordings, or integrate with CRM or contact center platforms. Simplify your phone hardware with IP desk phones or switch completely to softphones with headsets. Cloud VoIP technology gives you the ultimate flexibility to tailor your phone service to your specific business needs.

Most business VoIP phone services provide mobile and desktop apps to make and receive calls. Zoom’s desktop and mobile apps offer a unified communications experience, allowing you to elevate your phone call to a video call, or place a call on hold on one device and retrieve it from another.

Small business cloud VoIP FAQ

The cheapest VoIP phone services can be lacking in one area or another, so if you’re looking at lower-cost options, make sure you prioritize which features are most important to you before you begin your search. Simplify your costs with phone plans that include unlimited calling (no more metered minutes to share between users), enhanced business features at no extra cost, transparent monthly rates per user, and no set-up fees.

VoIP for small businesses allows several different options for choosing or keeping your business phone number. You can port phone numbers from your existing service provider or procure new ones. As a small business, keeping your existing phone number allows you to transition to VoIP service seamlessly with minimal disruption to your customers.

Long-distance calls using a landline are often charged by the minute, which can lead to unpredictable phone bills. VoIP plans often include options for international calling at a monthly or annual flat rate. If you do business globally, look for a business VoIP phone plan that offers unlimited international calling.

Setup costs of moving to a small business VoIP system are much lower than setting up a traditional landline system. Legacy on-premises solutions require extensive infrastructure and equipment, which are costly to install and maintain. VoIP business phone service requires virtually no infrastructure, other than an existing internet connection. You don’t even need to purchase desk phones because you can use any device, such as a smartphone or computer, to make calls.

Your small business VoIP provider also will handle the maintenance and management of your phone system as part of your monthly plan at an affordable, predictable price per user.

Business VoIP solutions require nothing more than an internet-connected device with a microphone and speaker to get started (you can also use a headset if you prefer). You can make and receive calls from your smartphone, tablet, or computer using a “softphone,” which is software that allows you to transmit calls over the internet.

If you’re used to a desk phone, Zoom Phone supports a number of hardware options that allow you to provide the traditional desk phone experience while enjoying all the benefits of VoIP service.

VoIP phone systems can be a great option for small businesses. With interpersonal communication at an all-time high for smaller businesses, the ability to work from your office or over mobile devices is an invaluable feature. Business VoIP solutions are generally more cost-effective for small businesses because they have fewer fees and add-on expenses.
