A 5×5 VoIP plan — five users, five lines — is the most common entry-point package for small businesses making the switch from traditional phone service. The price range is wide: $75 to $400 per month all-in, depending on features, provider tier, and the fees most vendors bury in the fine print. If you’re budgeting for VoIP in 2025 and you’ve seen quotes all over the map, this breakdown explains exactly what drives that variance and what a realistic number looks like for a five-person team. For more details, see our guide on comprehensive VoIP solution comparison for SMBs.
I’ve spent eight years analyzing SMB VoIP deployments, and the single biggest source of sticker shock isn’t the base subscription — it’s the stack of add-ons, regulatory fees, and contract penalties that don’t appear on the provider’s pricing page. This article gives you the line-by-line cost structure so you can evaluate any quote with clear eyes. For more details, see our guide on hidden fees and regulatory charges that inflate your bill.

What Does a 5×5 VoIP Plan Actually Cost in 2025?
A 5×5 VoIP plan for a small business typically runs $150 to $400 per month all-in, once you account for base subscription fees, taxes, hardware, and at least one or two feature add-ons. The base subscription alone — before any extras — averages $75 to $225 per month across major providers. That gap is explained almost entirely by the tier of service: entry-level plans from providers like Nextiva or RingCentral start around $15 per user per month; mid-tier plans with call recording, CRM integration, and analytics run $30 to $45 per user per month.

For more details, see our guide on avoid paying for VoIP features your team won’t actually use.
Three delivery models drive different cost structures: For more details, see our guide on how VoIP compares to traditional phone systems on total cost.
- Hosted VoIP (cloud PBX): Monthly subscription, no server hardware, provider manages infrastructure. Lowest upfront cost. Most SMBs land here.
- On-premises PBX: One-time hardware investment of $1,500 to $8,000 depending on system size, plus ongoing maintenance. Higher upfront, potentially lower long-run if you stay put for 7+ years.
- Hybrid models: Existing on-prem PBX connected to SIP trunks for PSTN access. Monthly SIP trunk costs average $15 to $25 per channel; a five-line setup runs $75 to $125/month plus your existing hardware maintenance.
For most five-person teams, hosted VoIP wins on total cost of ownership over a three-year horizon — unless you already own depreciated PBX hardware that’s still functional. For more details, see our guide on total cost of ownership analysis for remote team deployments.
Key takeaway: A realistic 5×5 hosted VoIP budget for 2025 is $150 to $400 per month all-in; the base subscription is only part of that number, and the difference between the low and high end comes down to features, taxes, and hardware choices.
What’s Actually Included in a 5×5 VoIP Plan — Line by Line?
Here’s where most pricing comparisons fail: they show the per-user rate and stop there. Below is the full cost structure you should build into any budget.
[IMAGE: alt=”Itemized VoIP cost table showing base fees, add-ons, taxes, and hardware for a 5-user SMB example” | filename=”voip-5×5-itemized-cost-table-2025.jpg”]
Base subscription: $75 to $225 per month for a five-user, five-line bundle. This covers unlimited domestic calling, basic voicemail, and a softphone app in most cases. Anything beyond that is usually an add-on.
Per-user feature add-ons — and these accumulate fast:
- Voicemail-to-email transcription: $3 to $5 per user/month
- Call recording (on-demand or automatic): $5 to $10 per user/month
- Auto-attendant / IVR: $10 to $20 per month flat, or included in mid-tier plans
- CRM integration (Salesforce, HubSpot, Zoho): $8 to $15 per user/month
- Video conferencing: $5 to $15 per user/month if not bundled
A five-person team that adds call recording and CRM integration can easily add $65 to $125 per month on top of the base rate.
Hardware: Desk phones run $80 to $300 each depending on model — a Polycom VVX 250 sits around $100 to $120 street price; a Yealink T57W with a color touchscreen runs $180 to $220. For five users, budget $500 to $1,500 for phones alone. If you’re keeping any analog fax lines or legacy devices, an ATA (Analog Telephone Adapter) adds $50 to $150 per unit.
Number porting fees: Porting your existing numbers to a new VoIP provider averages $20 to $50 per number in the U.S. For a five-line setup, that’s $100 to $250 as a one-time cost. Some providers waive this; many don’t advertise that they charge it at all.
Bandwidth: VoIP requires approximately 100 Kbps per concurrent call using the G.711 codec — more if you’re running video. For five simultaneous calls, that’s 500 Kbps of dedicated, low-latency bandwidth. If your internet connection is shared with heavy data traffic, you may need QoS configuration or an upgraded ISP plan, which is a real cost most VoIP quotes ignore entirely.
Regulatory fees and taxes: This is the one that surprises people most. Federal Universal Service Fund (USF) contributions, state 911 surcharges, and state communications taxes vary by location but commonly add 12% to 20% to your monthly bill. Some states — Florida, for example — have a Communications Services Tax averaging 14.89%, one of the highest in the country. These fees are legal pass-throughs, not provider markups, but they’re often listed as a single line item called “taxes and fees” with no itemization.
Put it all together for a five-user team with call recording and CRM integration, five desk phones amortized over three years, and average U.S. tax burden:
- Base subscription: $150/month (mid-tier, $30/user)
- Add-ons (call recording + CRM): $90/month
- Hardware amortized: $35/month
- Taxes and regulatory fees (~15%): $36/month
- Realistic total: $311/month
Key takeaway: The advertised per-user rate is typically 40% to 60% of your actual monthly cost once add-ons, hardware amortization, and regulatory fees are included — always build a full-stack budget before comparing providers.
What Hidden VoIP Fees Do Small Business Owners Miss Most Often?
The weird part? Most of these fees are disclosed — just not prominently. They’re in the service agreement, not the pricing page.
Contract termination penalties are the biggest financial trap. Most mid-tier VoIP providers offer 12 to 36-month contracts. Early exit penalties typically run $200 to $500 per line. For a five-line contract, that’s up to $2,500 if you switch providers at month eight because call quality is poor. Always ask for the termination fee schedule before signing — and get it in writing, not just verbally from a sales rep.
International calling overages hit businesses with any cross-border communication. Base plans almost universally cover domestic calls only. International rates from major providers range from $0.02 to $0.08 per minute for common destinations — but some business categories (importers, companies with Latin American trade relationships, firms with remote workers abroad) can accumulate $200 to $600 in monthly overages before anyone notices. The fix is an international calling bundle, which typically runs $10 to $30 per user per month.
SLA uptime gaps: Budget providers frequently advertise 99.9% uptime. That sounds strong. It translates to 8.76 hours of allowable downtime per year. Enterprise-grade SLAs promise 99.999% — that’s about 5 minutes of downtime annually. For a business where the phone is the primary sales channel, 8 hours of downtime during a busy period is a material revenue event, not an acceptable SLA term.
SIP fraud and toll fraud are underappreciated financial risks. Attackers scan for unsecured SIP endpoints and use compromised accounts to route international calls — sometimes generating thousands of dollars in charges overnight before the business owner notices. The FBI has documented VoIP fraud as a growing vector in business communications attacks. Providers that don’t include call anomaly monitoring or international call limits by default leave you exposed.
A real scenario: a hospitality SMB I tracked during a pricing analysis switched VoIP providers mid-contract and faced $1,200 in combined porting fees and early termination charges — none of which appeared in the initial quote. The new provider’s rate was $40/month cheaper, but the break-even on switching costs was 30 months. That’s not a savings. That’s a math problem.
Scalability pricing traps catch growing teams off guard. Adding a sixth user to a five-user plan often doesn’t cost you one additional user fee — it bumps you to the next pricing tier entirely. Some providers structure plans in bands: 1-5 users, 6-10 users, 11-20 users. Crossing a band boundary can increase your monthly bill by 20% to 35% for the same features.
Key takeaway: Contract termination fees, international call overages, SLA gaps, and tier-jump pricing are the four hidden costs that most commonly blow SMB VoIP budgets — always model the worst-case scenario for each before committing to a contract.

How Do You Compare VoIP Providers Without Getting Burned by Marketing Language?
Vendor-neutral comparison is harder than it sounds because every major provider optimizes their pricing page for the number that looks best, not the number you’ll actually pay. Here’s a structured approach.
Step 1: Build a standard requirements list before you look at any provider. Document your user count, expected concurrent calls, required features (call recording, CRM integration, auto-attendant), and any compliance requirements (HIPAA if you’re in healthcare, for example). This prevents providers from upselling you features you didn’t know you needed.
Step 2: Request a fully itemized quote — not a per-user rate. Ask specifically for: base subscription total, all feature add-ons, regulatory fees and taxes, hardware costs, number porting fees, and the termination fee schedule. Any provider that won’t give you this in writing before you sign is a provider worth skipping.
Step 3: Run a network readiness check. VoIP performance is only as good as your internet connection and internal network configuration. Before committing to any provider, run a VoIP quality test (tools like PingPlotter or your provider’s own pre-sales assessment) and confirm your router supports QoS prioritization for voice traffic. A $25/user/month plan on a congested network will sound worse than a $15/user/month plan on a properly configured one.
Step 4: Check the SLA terms, not just the uptime percentage. What’s the remediation process when uptime falls below the SLA? Is it a service credit? How do you claim it? Some providers offer credits that require you to file a ticket within 24 hours of an outage — a detail buried in the terms of service that most business owners never read until they need it.
Step 5: Verify security defaults. Confirm that SRTP (Secure Real-time Transport Protocol) and TLS (Transport Layer Security) encryption are enabled by default, not sold as a premium add-on. The NIST Special Publication 800-58 on VoIP security establishes encryption of voice traffic as a baseline requirement — any provider that charges extra for it is selling you a below-baseline product at a premium price.
Key takeaway: A structured five-step evaluation process — requirements first, itemized quotes, network readiness, SLA scrutiny, and security verification — is the only reliable way to compare VoIP providers without being misled by headline per-user rates.
What VoIP Security Risks Should Every SMB Understand Before Signing a Contract?
SIP fraud (Session Initiation Protocol fraud) is a category of attack where unauthorized parties exploit unsecured SIP credentials to make calls billed to your account. It’s not theoretical — the Communications Fraud Control Association (CFCA) estimated global telecom fraud losses at $38.95 billion in 2023, with VoIP-enabled toll fraud representing a significant share. Small businesses are disproportionately targeted because they’re less likely to have call anomaly detection in place.
SRTP and TLS encryption are the two technical standards that protect voice traffic in transit. SRTP encrypts the actual audio; TLS encrypts the signaling layer (call setup, routing). Both should be enabled by default on any plan you consider. If a provider’s documentation doesn’t explicitly confirm both, ask — and get the answer in writing.
VLAN segmentation separates your voice traffic from your general data network at the infrastructure level. This matters because a compromised device on your data network (a malware-infected laptop, for example) can’t reach your VoIP system if voice traffic runs on a separate VLAN. This is a network configuration step, not a provider feature — it’s something your IT support or MSP should implement during deployment.
Compliance implications for healthcare SMBs: If your business handles protected health information, your VoIP provider must sign a Business Associate Agreement (BAA) under HIPAA. Not all providers offer BAAs — RingCentral and Microsoft Teams Phone do; some budget providers don’t. Operating a HIPAA-covered entity on a non-BAA VoIP platform is a compliance violation regardless of whether a breach occurs. The HHS HIPAA Security Rule requires administrative, physical, and technical safeguards for ePHI — and voice communications can carry ePHI.
I’ll be honest: security is the section most SMB buyers skim because it feels abstract until something goes wrong. The businesses I’ve seen get hit with SIP fraud share one trait — they chose a provider based on price alone and never asked a single security question during the sales process. The financial exposure from a single overnight toll fraud event can exceed your annual VoIP subscription cost.
Key takeaway: SRTP/TLS encryption, VLAN segmentation, and HIPAA BAA availability are non-negotiable security requirements for SMB VoIP — verify all three before signing any contract, regardless of provider tier or price.

Frequently Asked Questions About 5×5 VoIP Pricing for SMBs
What is a 5×5 VoIP plan?
A 5×5 VoIP plan is a small business phone package structured for five users and five simultaneous call lines. It’s the most common entry-level configuration for SMBs moving from traditional landlines or a legacy PBX system to cloud-based VoIP. The “5×5” framing isn’t a formal industry term — it’s a practical shorthand for the smallest team size where you need concurrent line capacity beyond a single user.
How much should a small business budget for VoIP in 2025?
A five-user team should budget $150 to $400 per month all-in for hosted VoIP in 2025. The low end assumes a basic plan with minimal add-ons and existing hardware. The high end reflects a mid-tier plan with call recording, CRM integration, new desk phones amortized over three years, and full regulatory fee load. Most SMBs land between $200 and $320 per month once everything is accounted for.
What’s the difference between hosted VoIP and a SIP trunk?
Hosted VoIP is a fully managed cloud phone system where the provider handles all infrastructure — you just need internet access and phones. SIP trunking connects an existing on-premises PBX to the public telephone network via the internet, replacing traditional analog or ISDN lines. Hosted VoIP is typically simpler to deploy and maintain; SIP trunking is more cost-effective for businesses that already own functional PBX hardware and want to reduce per-line costs without replacing their entire phone system.
Are VoIP calls HIPAA compliant?
VoIP calls can be HIPAA compliant if the provider signs a Business Associate Agreement (BAA) and the system uses encryption (SRTP/TLS) for voice traffic in transit. Not all providers offer BAAs — confirm this before signing if your business handles protected health information. Using a non-BAA VoIP provider for calls that involve patient data is a HIPAA violation under the HHS Security Rule, regardless of whether a data breach occurs.
Can I keep my existing phone numbers when switching to VoIP?
Yes — the process is called number porting, and it’s legally protected under FCC regulations. Most providers complete domestic number ports within 2 to 10 business days. Porting fees average $20 to $50 per number; some providers waive them as a promotional offer. The critical step is not canceling your existing phone service before the port completes — doing so can result in permanent number loss, which is not recoverable.
