Phone.com Basic is the lowest advertised annual-billing entry plan among the fixed-price U.S. business VoIP plans compared here. Zoom Phone’s metered plan has a lower access price, but usage charges mean it is not a like-for-like alternative to an unlimited-calling plan. Which service is cheapest for you depends on billing cadence, calling destinations and volume, team size, and the features you actually need. Prices below are provider-published snapshots accessed October 4, 2026, and may change.
How this ranking compares prices
This is a comparison of advertised U.S. business VoIP starting prices, not a ranking of residential services or every phone system available. The plans differ in billing terms, calling allowances, and included features. Annual-billing prices are monthly equivalents, not necessarily month-to-month rates. Taxes and fees can also affect the final bill.

For a fair comparison, first decide how many users need service, whether you will pay monthly or annually, which countries you call, how much metered calling you expect, and whether you need desk phones, recording, or CRM features. The ranking below reflects the published entry prices and terms, not a universal lowest-cost winner.

1. Phone.com Basic: lowest fixed-price entry plan in this comparison
At $15 per user per month with annual billing, Phone.com Basic is the least expensive advertised entry plan among the fixed-price business plans compared here. That is $180 billed annually per user. It includes unlimited minutes, mobile and web apps, and standard voice features. The page also describes monthly billing, but the cited information does not establish its monthly price.
Basic is not the right match if you require an IP desk phone: Phone.com lists desk-phone compatibility on Plus, which costs $22.50 per user per month billed annually. Plus also adds voicemail transcription and conversational text messaging. Pro is $33.33 per user per month billed annually and adds call recording, analytics, and CRM integration. If any of those capabilities are essential, compare the tier that actually includes them rather than Basic’s headline price.

2. Zoom Phone US & Canada Unlimited: a clear monthly option
Zoom lists its US & Canada Unlimited plan at $16 per user per month with annual billing or $18 billed monthly. The monthly option can suit a team that values avoiding an annual commitment, while the annual price is the lower monthly equivalent. Both figures apply to the unlimited U.S. and Canada plan.

Ooma Office Essentials costs $19.95 per user per month and includes unlimited calling in the U.S., Canada, Mexico, and Puerto Rico.

That combination may make it a better fit than a lower-priced plan for a business that needs those features or regularly calls the additional listed destinations.
Ooma also lists Pro at $24.95 and Pro Plus at $29.95 per user per month. The cited rates page says applicable taxes and fees vary by locale; check the amount for your location when estimating the total.
Rank #4
- NOT LANDLINE PHONE: PROFESSIONAL VOIP PHONE ONLY! This device is a Voice over IP (VoIP) Phone and is NOT compatible with standard home landline/PSTN connections (RJ11). It REQUIRES a subscription to a SIP Service Provider (e.g., VoIP.ms, RingCentral, ) or an Active PBX System (e.g., 3CX, Asterisk, FreePBX) and network configuration to function.
- CRYSTAL CLEAR HD AUDIO & NOISE REDUCTION: Featuring advanced noise reduction technology and wideband codecs like G.722 and Opus, this VoIP phone ensures high-definition voice transmission. The HD handset and speaker provide stable, professional-grade communication even in busy or noisy office environments.

4. RingCentral RingEX Essentials: check the team-size cap and billing term
RingCentral RingEX Essentials is $19.99 per user per month billed annually or $29.99 billed monthly, and the cited Essentials plan is for up to 20 users.

Quick Recap
What to check before choosing the lowest price
- Match billing cadence. Compare annual-billing equivalents with annual-billing equivalents, and monthly rates with monthly rates. Annual pricing may reduce the monthly equivalent but requires an annual payment commitment.
- Estimate metered usage. A lower access price does not guarantee a lower total bill if calls are metered.
- Match calling destinations. Ooma Essentials lists unlimited calls to Mexico and Puerto Rico as well as the U.S. and Canada; the cited Zoom and RingCentral plans specify the U.S. and Canada.
- Price the features you need. Phone.com assigns IP desk-phone compatibility to Plus, and recording, analytics, and CRM integration to Pro. Compare the tier that covers your actual requirements.
- Check tax, fee, and eligibility details. Phone.com flags taxes and fees, Ooma says they vary by locale, and RingCentral Essentials has a 20-user limit.
- Confirm included numbers and equipment separately. The cited plans identify certain numbers and features, but do not establish that any particular physical handset is included. A compatible IP desk phone is an optional requirement for some setups, not a universal condition of VoIP service.
