Frequently Asked Questions
How much does VoIP cost for a small business?
Most small business VoIP plans cost $10 to $30 per user per month when billed annually. A team of 5 typically pays $50 to $150 per month. Add taxes and regulatory fees of 15 to 25 percent and your real bill is higher than the advertised price. For 5 users on Nextiva at $15 per user, expect to pay around $90 to $95 per month all-in, compared to $200 to $300 for equivalent landlines from AT&T or Verizon.
What internet speed do I need for VoIP?
VoIP uses roughly 100 Kbps per simultaneous call. A standard 25 Mbps broadband connection can handle 200 or more concurrent calls. Speed is rarely the problem. Latency and packet loss matter far more than raw download speed. A connection with 150 ms latency or under 1 percent packet loss will deliver clear calls. Avoid shared public Wi-Fi for important business calls.
Can I keep my existing business phone number?
Yes. Number porting transfers your existing number to your new VoIP provider. The process takes 1 to 4 weeks depending on your current carrier. Your VoIP provider handles the paperwork. You will need your account number and PIN from your current carrier plus a recent phone bill. During the transition, calls continue reaching your old number so there is no service gap.
Is VoIP reliable enough for business use?
Modern cloud VoIP services offer 99.9 to 99.999 percent uptime SLAs. The main risk is your internet connection, not the VoIP service itself. Most VoIP providers automatically route calls to your mobile when your broadband drops, so customers rarely notice an outage. For businesses in areas with unreliable internet, keep a 4G hotspot as a backup. Nextiva and RingCentral both have mobile failover built into every plan.
Do I need special hardware for VoIP?
No. Every major VoIP provider offers a desktop and mobile softphone app. You can make and receive calls using your existing laptop, phone, or tablet with no additional hardware. If you want physical desk phones, VoIP-compatible IP phones from Yealink or Poly cost $50 to $200 each. Many small businesses run softphone-only for years without issues. Hardware becomes worthwhile when staff need hands-free calling or a dedicated receptionist phone.
What is the cheapest business VoIP service?
Google Voice starts at $10 per user per month but requires a Google Workspace subscription ($6 per user extra) making the real cost $16 per user minimum. Zoom Phone metered plan starts at $10 but charges per minute for calls. For a full-featured system with unlimited calls, Nextiva Core at $15 per user per month is the cheapest option for teams of 3 or more.
