VoIP is something which has increased a lot in the past few years. Voice over Internet Protocol (VoIP) carries phone calls as data over an internet connection instead of a traditional phone line, so most businesses now run their phones through a cloud provider rather than an on-site phone system. There are many VoIP service providers, and their plans differ widely in price, features and contract terms.

What Is a Business VoIP Service?
A business VoIP service is a cloud phone system that sends calls over the internet as data packets instead of over the traditional public switched telephone network (PSTN). Employees can make and take calls on desk phones, a desktop app or a mobile app using the company number. The provider hosts the phone system, often called a cloud PBX, so there is no on-site hardware to maintain. For a closer look at setup, see our guide to the cloud PBX functions to configure first.
How to Choose a VoIP Service Provider
- Count users and locations. Per-user pricing means a 10-person team pays ten times the listed rate each month.
- Compare the same billing term. Annual billing is cheaper: RingCentral says annual billing saves up to 33%, and Nextiva says up to 50%.
- List must-have features. Check whether an auto attendant or virtual receptionist, ring groups, call recording, SMS, video meetings and call queues are included in the tier you can afford. Ooma, for example, adds call recording only from its Pro plan.
- Check integrations and call handling. Teams that route many calls may need call management software or a full cloud contact center.
- Test your network. Call quality depends on the internet connection; latency, packet loss and jitter all degrade VoIP calls.
- Read the contract. Look for regulatory fees, number porting charges and cancellation terms before signing.
Common Mistakes When Switching to VoIP
- Comparing annual prices with monthly prices. A plan advertised at $20 on annual billing can cost $30 month to month.
- Ignoring the internet connection. Congested links add delay and dropped audio; see these ways to improve internet speed.
- Forgetting emergency calling. Unlike a landline, a VoIP number has no fixed link to a physical address, so make sure every user’s emergency address is registered with the provider and kept up to date.
- Buying from an unknown reseller without checks. Many VoIP plans are sold through resellers; understand how VoIP resellers work before signing.
