Buyer's guide

What is a VoIP Business Phone System?

A VoIP (Voice over Internet Protocol) business phone system transmits calls over the internet instead of traditional phone lines. This allows for advanced features like auto-attendants, call routing to mobile devices, and integration with other business software, all managed from a cloud-based portal.

How does VoIP pricing work?

Most VoIP providers charge on a per-user, per-month basis. Pricing tiers are typically based on the number of users and the feature set included, such as call recording, analytics, or specific integrations. Be aware that some providers require annual contracts for the best rates.

Do I need special hardware for a VoIP system?

No, special hardware is not always required. You can make and receive calls using a software application (a 'softphone') on your computer or a mobile app on your smartphone. However, for a traditional desk phone experience, you can purchase VoIP-compatible IP phones.

How to choose

1.First, list your must-have features, such as an auto-attendant, call recording, or a specific CRM integration.
2.Next, determine your budget per user per month and whether you prefer a monthly or annual contract.
3.Then, check each provider's reliability metrics, such as their uptime SLA, which should be 99.99% or higher.
4.Finally, read recent user reviews focusing on call quality and the responsiveness of customer support before making a final decision.

Frequently asked questions

What is the best VoIP system for a very small business (1-5 people)?

For very small businesses, providers like Ooma, Grasshopper, or our wildcard pick OpenPhone are excellent choices. They offer simple setup, affordable entry-level plans, and core features designed for teams that don't need the complexity of a large enterprise system.

Can I keep my existing business phone number?

Yes, virtually all VoIP providers allow you to keep your existing business phone number through a process called 'porting'. The process is managed by your new provider and typically takes 1-4 weeks to complete without interrupting your service.

How much does a VoIP system cost per month?

A business VoIP system typically costs between $15 and $45 per user per month. The exact price depends on the provider, the number of users (more users often means a lower per-user price), and the feature set included in your plan.

Is VoIP as reliable as a landline?

Yes, modern VoIP service is as reliable as a landline, provided you have a stable, high-speed internet connection. Top providers guarantee uptime of 99.999%, which translates to less than 6 minutes of potential downtime per year.
