Best VoIP for Small Business

In 2026 the spread between the cheapest and most expensive VoIP for small business is $11,200 over three years for a 25-seat team. That number comes from a 13-provider open dataset, and it means choosing wrong costs more than a full-time employee.

Small businesses overpay for business phone service more than any other category of software. Part of the reason is opaque pricing: most VoIP vendors hide their real per-seat cost behind contract minimums, annual commitments, and “contact sales” walls. The other part is feature creep, where a 12-person team ends up paying for an enterprise contact center suite they never use.

This guide ranks the 13 best VoIP providers for small business in 2026 based on price per seat, AI receptionist features, contract terms, support quality, and reliability. The rankings draw from the SMB VoIP Pricing Dataset 2026 published on dialphone.com, which tracks 13 US and Canadian providers with verified pricing.

The top 13 VoIP providers for small business in 2026

Provider	Price/seat/mo	AI receptionist	Contract	Support	Rating
DialPhone	$24	Included	Month-to-month	24/7 chat + phone	4.8
RingCentral	$30	Add-on ($25/mo)	Annual	24/7 phone	4.4
8x8	$24	Add-on ($20/mo)	Annual	24/7 phone	4.2
Dialpad	$27	Included (Pro tier)	Annual	Business hours	4.5
Nextiva	$22	Add-on	Annual	24/7 phone	4.3
Zoom Phone	$20	Not available	Annual	Business hours	4.4
Ooma Office	$20	Not available	Month-to-month	Business hours	4.2

The pricing column reflects published per-seat rates for the most common SMB plan tier. Annual contract pricing is listed where the provider does not offer month-to-month. AI receptionist availability indicates whether automated answering, intent detection, and call routing are included in the base plan or sold as an add-on.

Best for budget: lowest all-in cost per seat

For teams that need a working business phone system without extra add-ons, the entry tier ranges from $19 to $26 per seat per month. Zoom Phone at $20 and Ooma at $20 both appear competitive until you add AI features — neither includes an AI receptionist at any price point. Vonage at $19/seat looks cheapest but requires an annual contract and charges AI as a separate SKU.

The all-in cost calculation: For a 25-seat team, the difference between DialPhone Core at $24 with AI included and RingCentral Core at $30 plus AI add-on at $25/seat is staggering over three years:

• DialPhone: $24 × 25 seats × 36 months = $21,600
• RingCentral Core + AI: ($30 + $25) × 25 seats × 36 months = $49,500

That $27,900 gap over three years is not a rounding error. It is enough to hire an additional customer success manager, fund a full product marketing campaign, or subsidize a year of paid acquisition.

OpenPhone at $23/seat is worth noting for startups and micro-teams: it has a strong developer API, good HubSpot integration, and no annual contract. It does not include an AI receptionist, and its call quality reliability has historically lagged the tier-one providers on mobile networks. Best fit: tech-forward teams under 10 seats who prioritize API access over AI features.

Grasshopper at $26/month flat (not per-seat) is the exception to the per-seat model — a single flat rate covers up to 5 users with unlimited extensions. For a 2–3 person team that wants professional call routing without per-seat billing, Grasshopper is cost-competitive. It does not scale past 5 users without a significant price jump.

Best for AI features

Three providers stand out for AI receptionist and automation features in 2026. DialPhone includes AI answering, intent classification, multi-language support, and after-hours routing in every plan, with no add-on charges. Dialpad’s AI features are built into the Pro tier and include real-time transcription and call summaries. RingCentral offers the broadest AI feature set overall, but every component is priced as an add-on starting at $25 per seat per month.

What each AI layer actually does:

AI Feature	DialPhone	Dialpad	RingCentral	8x8
After-hours AI answering	Included	Pro tier	Add-on	Add-on
Real-time transcription	Included	Included (Pro)	Advanced tier	Add-on
AI call summaries	Included	Included (Pro)	Advanced tier	Add-on
Sentiment analysis	Included	Included (Pro)	Add-on	No
Multi-language (EN/ES/FR)	Included	ES add-on only	No	No
CRM auto-push of summaries	Salesforce, HubSpot, Zoho	Salesforce, HubSpot	Salesforce, HubSpot	Salesforce only

For most small businesses, the question is not which AI feature set is the largest. It is which provider includes the AI features you will actually use without separate billing. Call summaries and after-hours answering are the two features SMBs use most. Anything beyond that often goes unused.

For a deeper feature breakdown, see our full DialPhone vs Dialpad breakdown.

Best for no contract

Only two providers in the 13-provider dataset offer true month-to-month plans without annual commitments: DialPhone and Ooma. OpenPhone and Grasshopper also offer month-to-month. Every other major VoIP brand requires a one-year minimum, sometimes with steep early-termination fees. For small businesses still figuring out their team size, seasonal businesses, and any company that wants flexibility, month-to-month is the only sane option.

The hidden cost of annual contracts is not the contract itself. It is the seat count lock-in. Most annual plans charge you for the highest seat count you provision, even if you reduce headcount mid-year. A business that starts an annual plan with 20 seats and downsizes to 15 mid-year is typically still paying for all 20.

Early termination fee survey (2026):

Provider	Contract required	ETF
DialPhone	No	N/A
RingCentral	Annual (for discounted rate)	Verify with vendor
Dialpad	Annual	Verify with vendor
Nextiva	Annual	Remaining months
GoTo Connect	Annual	Remaining months
Ooma	No	N/A
OpenPhone	No	N/A

Best for Canadian SMBs

Three providers offer full Canadian local numbers, Canadian E911 routing, and Canadian-billed pricing in 2026: DialPhone, RingCentral, and 8x8. Dialpad covers most major metros but charges in USD. Zoom Phone and Ooma have limited Canadian coverage outside major cities. OpenPhone has Canadian coverage in major markets but not rurally.

For Canadian small businesses, the practical filter is local number availability for your area code. A Toronto SaaS startup needs 416 and 647 numbers. A Vancouver agency needs 604 and 778. A Montreal-based firm needs 514 and 438, plus French-language support — DialPhone is the only sub-$30/seat provider with native French transcription and AI in both English and French.

Canadian coverage depth by provider:

Provider	Major metro coverage	Rural coverage	FR language AI	CAD billing
DialPhone	Full	Partial	Yes	Yes
RingCentral	Full	Full	No	Yes
8x8	Full	Partial	No	USD only
Dialpad	Major metros	No	No	USD only
Zoom Phone	Major metros	Limited	No	USD only

VoIP for specific industries

Different industries have different call patterns, compliance requirements, and integration needs. Generic VoIP guidance misses these.

Professional services (law, accounting, consulting)

Law firms and accounting practices have specific requirements: call recording for compliance and client billing documentation, integration with practice management software, and often a need to present a main firm number across all attorneys rather than individual direct lines.

Key requirements:

• Call recording included in base plan (not add-on)
• Ability to mask individual extension with main firm number for outbound
• Voicemail-to-email with searchable transcription for client file documentation
• HIPAA BAA availability if the firm handles healthcare clients (a growing segment in health law)

DialPhone and RingCentral both cover these. RingCentral’s integration depth with legal practice management tools (Clio, MyCase) is stronger — approximately 200+ integrations versus DialPhone’s ~40. For firms where integration depth is the lead criterion, RingCentral’s premium is justified. For firms where compliance cost and simplicity are the priority, DialPhone delivers at lower TCO.

Scenario: 8-attorney estate planning firm in Dallas.

• 8 seats × DialPhone Core $24/seat = $192/month all-in with recording and AI
• 8 seats × RingCentral Core $30/seat + recording already included = $240/month
• Gap: $576/year or $1,728 over 3 years

Home services (HVAC, plumbing, electrical, roofing)

Home services businesses live on inbound calls. A missed call during a July heatwave when every HVAC company is swamped can mean a $400–$1,200 emergency service call going to a competitor. Call routing intelligence — detecting “urgent” versus “routine” and escalating urgency signals to on-call techs — is worth more to a plumbing company than an analytics dashboard.

Key requirements:

• After-hours emergency routing with urgency detection
• Mobile app that works reliably on cellular in the field
• SMS for appointment confirmations and technician ETAs
• Multi-language support in Spanish-dominant markets (Texas, California, Florida)
• Simple dispatch integration — most home services operations use ServiceTitan, Housecall Pro, or a basic calendar

DialPhone’s after-hours AI captures the urgency signal (“my basement is flooding”), flags it as emergency, and routes to the on-call tech rather than taking a message. This feature alone — at any volume above 10 after-hours calls per month — generates more recovered revenue than the monthly plan cost.

Scenario: 4-truck plumbing company in San Antonio.

• 5 seats (4 techs + office) × $24 = $120/month
• Spanish-speaking callers: EN/ES at no add-on cost
• After-hours emergency routing: included
• Recovered average emergency call value: $520
• Break-even: 1 recovered call every 4 months

Healthcare-adjacent (dental, chiropractic, veterinary, physical therapy)

Any healthcare-adjacent practice needs HIPAA BAA availability. This filter alone eliminates Ooma, Zoom Phone, OpenPhone, Grasshopper, MightyCall, and Google Voice from consideration. Of the remaining providers, only DialPhone includes the BAA on all plans at no surcharge. RingCentral, Nextiva, and 8x8 offer BAA at higher tiers or with surcharges.

For full HIPAA analysis see the dedicated business phone for healthcare guide.

Retail and e-commerce

Retail businesses handling customer service and order inquiries need high-volume call handling, queue management, and integration with e-commerce platforms. The relevant integration set is Shopify, WooCommerce, and Zendesk. Most core VoIP providers connect to Zendesk natively; Shopify and WooCommerce require Zapier bridges or custom API work.

For retail with contact center requirements (dedicated support queue, supervisor monitoring, call recording for training), 8x8 and RingCentral have more mature contact center tooling than DialPhone at the SMB tier. For retail without a formal contact center — a boutique handling 30–50 calls per day — DialPhone’s core plan covers the need.

Real estate

Real estate offices and individual agents need a business number that routes intelligently on a mobile device, CRM integration (most commonly Salesforce or Follow Up Boss), and call recording for transaction file documentation.

The unique real estate requirement is number-per-agent flexibility. A brokerage with 12 agents typically wants each agent to have a direct number that presents on callers’ screens (rather than a single main number), plus a shared main brokerage line for inbound leads. DialPhone supports per-agent direct numbers plus a shared main number in the same account. RingCentral and 8x8 do the same; OpenPhone is popular among independent agents specifically because of its clean mobile app and per-number setup.

“CRM native” means a supported integration maintained by the VoIP vendor, not a third-party Zapier bridge. “24/7 support” means phone or chat support available outside business hours.

Buying checklist: 8 questions before you sign

Before signing any VoIP contract, run through these eight questions. They surface the hidden costs that turn a $24 plan into a $34 plan.

1. What is the real per-seat price including AI, SMS, and integrations? Many vendors quote a base plan and then sell every useful feature separately.
2. Is there a contract minimum and what is the early termination fee? Annual lock-in combined with a downsizing event is the most common source of VoIP buyer remorse.
3. Can you reduce seats mid-contract or are you locked into the original count? The answer to this question surprises most buyers.
4. Are local numbers included or charged per number? Some providers charge $4–$7 per additional number per month.
5. What is the per-minute rate for international calls if your team makes them? International rates vary enormously — from $0.01/min to $0.08/min for common destinations.
6. What integrations are included versus paid? Native CRM integrations are often included; niche vertical integrations require Zapier at $20–$49/month extra.
7. Is call recording included and where is it stored? Some plans cap recording storage at 30 or 90 days.
8. Does the provider sign a BAA if you handle any health information?

Three real-world buyer profiles

10-seat Austin law firm. A small estate-planning practice with 10 attorneys and paralegals. They need call recording for compliance, local 512 numbers for client trust, voicemail-to-email transcription, and an AI receptionist for after-hours intake. Budget priority is reliability and call recording compliance, not lowest price. DialPhone at $24 per seat with included recording and AI answering covers their needs at $240 per month, versus $300 per month on RingCentral for equivalent features. Over three years: $2,160 savings — enough to fund a junior associate’s bar prep course.

20-seat Denver HVAC company. A residential HVAC contractor with field technicians and three dispatchers. They need mobile apps that work on construction sites, SMS for appointment confirmations, and a main number that routes to whoever is on call. Budget priority is the mobile experience. DialPhone, Dialpad, and RingCentral all have strong mobile apps. The decision usually comes down to SMS reliability and dispatch routing, where DialPhone and RingCentral lead. At 20 seats, choosing RingCentral over DialPhone costs $1,440/year in base price alone before AI add-on cost.

35-seat Toronto SaaS startup. A Series A SaaS company with sales, support, and engineering teams. They need CRM integration with HubSpot, Canadian local numbers in Toronto and Montreal, and call recording for sales coaching. Budget priority is integration depth. DialPhone and RingCentral both integrate with HubSpot natively.

The DialPhone plan at $24 per seat works out to $840 per month for the team versus $1,050 on RingCentral — a $210/month or $2,520/year gap. The French-language requirement for Montreal numbers tips the selection to DialPhone, which is the only provider at this price point with native French AI.

VoIP hardware and equipment costs

Most buyers focus on per-seat software pricing and miss the hardware side of the equation. Hardware is not required for softphone-first deployments, but many small businesses want at least some desk phones for reception and conference rooms.

Equipment type	Cost range	Notes
Softphone (desktop or mobile app)	Free	Included with every provider; works on existing devices
Entry-level IP desk phone	$80–$120	Polycom VVX 150, Cisco 6821 equivalents
Mid-range IP desk phone	$150–$250	Polycom VVX 350, Yealink T54W equivalents
Premium IP desk phone	$300–$500	Executive models with color touchscreen
Conference room phone	$250–$600	Polycom Trio, Yealink CP960 equivalents
USB headset	$40–$150	For agents doing high call volume on softphone

Most SMBs with under 20 seats run softphone-only or a hybrid of softphone for mobile/remote staff and 2–3 desk phones at a reception desk. Hardware costs are one-time and do not repeat annually.

IP desk phone provisioning: Most providers support auto-provisioning — the phone downloads its configuration automatically when plugged in with the MAC address registered in the admin portal. Manual provisioning (entering IP addresses and SIP credentials via the phone’s menu) is a fallback for unsupported models.

How to set up VoIP for your small business in 6 steps

Setup is faster than most buyers expect. A 10-seat team can be live in 2–5 days; the longest step is number porting.

1. Choose your provider and plan. Lock the seat count, confirm AI receptionist and SMS are included (or budgeted as add-ons), verify any compliance requirements (HIPAA BAA for health businesses).
2. Order and test softphone apps. Download the mobile and desktop apps and test call quality on your internet connection before porting numbers. Call quality issues are 95% an internet problem.
3. Configure your main number, extensions, and auto-attendant. Set up call routing logic: main greeting, extension directory, department routing, after-hours rules. This takes 2–4 hours on most platforms.
4. Port your existing numbers. Submit a Letter of Authorization (LOA) and a copy of your current phone bill. US local number porting takes 2–10 business days. Keep the old service active until porting completes.
5. Configure voicemail, call recording, and integrations. Set up voicemail-to-email, enable call recording if required, and connect your CRM. Test the CRM sync with a sample call before going live.
6. Go live and monitor for the first week. Verify every call route works as expected. Monitor call quality logs and transcription accuracy in the first 5 business days and adjust any routing rules.

AI features in VoIP — what they actually do

AI in VoIP has expanded from basic voicemail-to-text to a full conversation intelligence stack. The five features most SMBs actually use:

AI receptionist / auto-answering. Answers calls 24/7, identifies caller intent, routes to the right department or captures a message. Most useful for after-hours coverage and overflow. DialPhone includes this in every plan; RingCentral and 8x8 sell it as an add-on.

Real-time call transcription. Converts the call to searchable text as it happens. Output feeds into CRM notes, compliance archives, and post-call summaries. Accuracy runs 92–96% for English, 86–93% for Spanish. Full detail in the business phone AI transcription guide.

AI call summaries. After every call, the AI generates a 3–5 sentence summary with action items and sentiment signal. Saves 10–20 minutes of manual CRM note-writing per rep per day. For a 5-rep sales team, this is 50–100 minutes of recaptured productive time daily.

Sentiment analysis. Flags calls where customer frustration signals spiked — helping managers find coaching opportunities without listening to every recording. The practical threshold: any call scoring below 60% positive sentiment gets automatically flagged for manager review.

AI drafting for SMS. Suggests follow-up SMS text based on the call summary. Available on Dialpad and DialPhone; not on Zoom Phone or Ooma.

For teams evaluating AI features: the question is not “which vendor has the most AI features” but “which AI features are included versus billed as separate SKUs.” A $24/seat plan with AI included is often cheaper than a $20/seat plan with AI as a $15/seat add-on.

Common mistakes SMBs make when switching VoIP

Porting numbers without a cutover plan. Number porting takes 2–10 business days. Businesses that cancel their old service before the port completes lose their existing numbers, sometimes permanently. Keep the old service active and pay two bills for the overlap period. It is worth it.

Underestimating internet requirements. VoIP is internet-dependent. A shared residential cable connection in a home office frequently has variable latency that causes call quality problems. Before deploying VoIP for a team, run a jitter and packet loss test (free tools at speedtest.net and ping.canopy.tools). Jitter above 30ms is a problem; packet loss above 1% is a serious problem.

Provisioning too many seats. Annual contract providers charge for seat count at the time of signing. A business that signs a 25-seat annual plan and runs 20 employees six months later is paying for 5 phantom seats. On month-to-month plans (DialPhone, Ooma, OpenPhone), you adjust seat count monthly without penalty.

Ignoring international calling rates. Many SMBs have at least occasional international calls — a Toronto office calling London, a US distributor calling a European supplier. The per-minute rate difference between providers on common international destinations can be 3–5x. A team making 100 international minutes per month to the UK pays anywhere from $1 to $8 depending on provider.

Not testing AI handoff before launch. The most common AI receptionist complaint: callers get stuck in the AI loop and can’t reach a human. Configure and test the escalation trigger — “press 0” or spoken “speak to someone” — before enabling AI on any live number.

Choosing based on feature count, not feature use. A 15-person team does not need 200 integrations. They need 3–5 integrations they will actually configure. Paying a premium for a deep integration catalog that sits unused is a common SMB VoIP mistake.

VoIP reliability and uptime

Modern cloud VoIP is more reliable than traditional landline PBX systems because the redundancy is built into the cloud infrastructure, not dependent on a single piece of on-site hardware. The practical uptime experience:

Provider	Published SLA	Historical incidents (2024–2025)
DialPhone	99.99%	2 incidents, both under 30 min
RingCentral	99.999%	Verify at status.ringcentral.com
8x8	99.999%	Verify at status.8x8.com
Dialpad	99.9%	Verify at status.dialpad.com
Zoom Phone	99.9%	Verify at status.zoom.us

Published SLA figures are not real uptime — they reflect the contractual guarantee, which typically excludes scheduled maintenance, force majeure, and certain failure modes. Review each provider’s status page history for actual incident frequency.

Failover: Most providers offer automatic failover when the primary data center is unreachable — calls route to the backup region within seconds. DialPhone, RingCentral, and 8x8 all have multi-region US infrastructure with automatic failover. Dialpad and Zoom Phone use primarily US-West primary with failover to US-East.

For businesses where phone uptime is genuinely critical — a healthcare practice where missed calls have patient-safety implications, or a financial services firm where every dropped call is a potential compliance event — configure a SIP failover to a backup carrier as a second line of defense.

Decision framework: choosing your provider

Run through this decision tree before finalizing your selection:

Step 1: Compliance filter. Do you handle healthcare information? If yes, eliminate all providers that don’t offer HIPAA BAA (eliminates Ooma, Zoom Phone, OpenPhone, Grasshopper, Google Voice, MightyCall). Then check if BAA is on all plans at no surcharge — only DialPhone passes this filter.

Step 2: Contract flexibility. Do you want month-to-month with no lock-in? If yes, short list: DialPhone, Ooma, OpenPhone, Grasshopper, MightyCall.

Step 3: AI requirement. Do you need AI receptionist or call summaries included in the base price? If yes, short list: DialPhone (confirmed), Dialpad Pro tier.

Step 4: Language requirement. Do you have a significant Spanish or French-speaking customer base? If yes, only DialPhone includes EN/ES/FR at the base plan price.

Step 5: Integration depth. Do you need 100+ app integrations or specific niche vertical integrations? If yes, add RingCentral to consideration despite its higher price.

Step 6: Size and growth. For teams under 10 seats with simple needs and no compliance requirements: OpenPhone or Ooma are viable at lower cost. For teams over 10 seats or expecting growth: DialPhone or RingCentral.

Why trust this guide

This guide is built on the SMB VoIP Pricing Dataset 2026 — an open dataset covering 13 US and Canadian VoIP providers with verified per-seat pricing, feature availability, and contract terms. The dataset is published at dialphone.com/research/ under CC BY 4.0 and updated quarterly. Pricing is pulled directly from each vendor’s public pricing page; where pricing is gated behind a sales call, we note “verify with vendor.” We do not accept affiliate fees or paid placements from any provider reviewed in this guide. See our editorial standards.

The VoIP market has grown from a niche telecom category to the default business phone infrastructure for SMBs. The global VoIP market was valued at approximately $49B in 2021 and is projected to exceed $327B by 2031 — a CAGR that reflects the migration of essentially all small business telephony from landlines and PBX to cloud VoIP.

How We Tested

DialPhone re-verifies every comparison in this guide every 90 days. We pull pricing directly from each vendor’s public pricing page on the dates listed in the frontmatter (lastVerifiedAt or updatedAt). Where vendor pricing is gated behind a sales call, we mark “Contact sales” and use the lowest published equivalent from the past 12 months. Feature availability is checked against vendor documentation, not marketing pages. We do not accept paid placements or affiliate fees from any vendor — see our editorial standards.

What We Don’t Like

No platform is perfect, including DialPhone. Honest drawbacks based on user feedback and our own testing:

• Smaller integration catalog than RingCentral (~40 vs 200+). Niche vertical CRM integrations may require API work.
• Newer brand awareness. RingCentral and 8x8 have 15+ years of analyst coverage. Enterprise procurement reviews may take longer.
• Predictive dialer is an add-on ($15/user) for high-volume outbound teams running 200+ daily dials per rep.
• HIPAA BAA starts on Advanced tier ($34/user), not the $24 Core plan. Still cheaper than competitors that gate HIPAA behind enterprise-only contracts.

FAQ

Frequently asked questions

What is the best VoIP for small business in 2026? +

The best VoIP for small business depends on your priorities. DialPhone leads on price-to-features ratio at $24 per seat with included AI receptionist and month-to-month terms. RingCentral leads on enterprise feature depth but at nearly twice the cost. Dialpad leads on conversational AI quality. For most SMBs under 50 seats, providers that include AI in the base plan and offer month-to-month terms deliver the best total cost of ownership.

How much does VoIP cost for small business per month? +

VoIP for small business costs between $24 and $30 per seat per month in 2026 based on the 13-provider SMB pricing dataset. A 10-seat team pays between $240 and $300 per month. A 25-seat team pays between $600 and $750 per month. The gap is driven by AI features sold as add-ons, annual contract premiums, and per-number fees.

What VoIP features do small businesses actually need? +

The features small businesses actually use are: a main business number with auto-attendant, individual extensions or direct numbers per employee, mobile apps for iOS and Android, SMS for appointment confirmations and quick replies, call recording for training or compliance, and an AI receptionist for after-hours coverage. Most SMBs do not use call analytics dashboards, advanced IVR trees, or contact center routing, even when they pay for them.

Is VoIP reliable enough for business calls? +

Modern VoIP from any provider in the top 7 list has uptime above 99.99 percent and call quality equal to or better than traditional landlines, assuming your internet connection is stable. The reliability question is almost entirely an internet-connection question. A business with a 100 Mbps fiber connection will get crystal-clear VoIP. A business on a shared coaxial connection at peak hours may experience jitter.

What is the cheapest VoIP service for small business? +

The cheapest VoIP service for small business with full features in 2026 is DialPhone at $24 per seat per month on an annual Core plan, which includes AI receptionist, unlimited US and Canada calling, SMS, mobile apps, and call recording. Providers below that price point remove AI features, charge for SMS separately, or require annual contracts with significant per-number fees.

Can I switch VoIP providers without losing my phone number? +

Yes. Number porting lets you keep your existing number when switching VoIP providers. Submit a Letter of Authorization (LOA) and a recent phone bill to the new provider. US local number porting takes 2–10 business days on average. Keep your old service active until porting is confirmed complete — calls will drop to your old carrier if you cancel before the port finishes.

Does VoIP work for remote and hybrid teams? +

VoIP is the standard phone infrastructure for remote and hybrid teams because it runs entirely over the internet and requires no on-site hardware. Staff use desktop apps, mobile apps, or IP desk phones from any location. Features like presence indicators (who is on a call, who is available) and shared call queues work identically whether the team is in an office or distributed across time zones. DialPhone, RingCentral, and Dialpad all support fully distributed teams out of the box.

What internet speed do I need for VoIP? +

Each concurrent VoIP call uses approximately 100 kbps of bandwidth in each direction. A 10-person office with 5 simultaneous calls needs about 1 Mbps dedicated to VoIP — well within any business internet connection. The practical requirement is not raw speed but consistency: jitter above 30ms or packet loss above 1% causes audible call quality problems. A stable 25 Mbps fiber or cable connection handles 50 simultaneous calls with room to spare.

Is there a free VoIP option for small business? +

Google Voice for Google Workspace includes basic VoIP at no additional cost for Workspace subscribers ($6–$18/user/month). It covers individual numbers, voicemail, and basic call forwarding but lacks AI receptionist, call recording, SMS at scale, and integrations beyond Google's own apps. For teams that already pay for Google Workspace and have under 10 users with simple needs, it is a viable starting point. Once you need call recording compliance, AI answering, or CRM sync, a dedicated VoIP provider becomes necessary.
