Key Takeaways
- Most Dallas offices pay roughly $20 to $45 per user each month for a hosted phone system.
- Setup typically runs from nothing to a few thousand dollars, depending on cabling and number porting.
- Desk phones cost about $80 to $300 each, and you may not need them for everyone.
- Taxes, E911 fees and add-on features can raise a bill by 10 to 25 percent.
- An on-premises system costs more up front but may cost less over seven or more years for large sites.
If you are shopping for a new phone system, the price you see on a website is rarely the price you pay. A VoIP phone service might advertise $19 per user, then add fees for taxes, extra numbers, call recording and desk phones. By the time the first invoice arrives, the total can be well above what you budgeted.
This guide breaks down what Dallas businesses typically pay. You will see setup costs, monthly rates, hardware, cabling and the small line items that add up. The numbers are typical ranges, not quotes. Your real price depends on headcount, call volume, how many locations you have and what you already own.
Read it with your own office in mind. A ten-person insurance agency in Richardson has very different needs from a 45-person engineering firm near Las Colinas with two floors and a warehouse. Use the sample budgets later in the post to find the one closest to you, then adjust.
The Short Answer: What Dallas Businesses Typically Pay
For a hosted system, most Dallas small businesses pay about $20 to $45 per user each month. The low end gets you calling, voicemail, a mobile app and a basic auto attendant. The high end adds video meetings, call recording, analytics and contact center features.
Setup is a separate number. Many providers charge little or nothing to activate cloud service. You pay more when you need new network cabling, a better switch, desk phones or help moving existing numbers. A clean setup for a small office usually lands between $0 and $2,500. A multi-floor or multi-site job can reach $5,000 to $15,000 or more.
Over three years, a 20-user office on a mid-range plan might spend $17,000 to $35,000 in total. That includes monthly fees, phones and a one-time setup. It is a wide range because features and equipment choices vary so much.
What Makes Up the Monthly Bill
The monthly bill is more than a per-user rate. Knowing each piece helps you compare quotes fairly, because two providers can price the same service in very different ways.
| Line Item | Typical Monthly Cost | What It Covers |
|---|---|---|
| Per-user license | $20 to $45 | Calling, voicemail, app, basic routing |
| Extra phone numbers | $1 to $5 each | Direct lines, fax numbers, department lines |
| Auto attendant & call queues | $0 to $25 per queue | Menus, ring groups, after-hours routing |
| Call recording | $5 to $15 per user | Storage and playback of recorded calls |
| Toll-free number & minutes | $5 to $20 plus usage | Customer-facing 800 numbers |
| Taxes & regulatory fees | 10 to 25 percent of bill | Federal, state and E911 charges |
| Support or management | $0 to $10 per user | Moves, adds, changes and help desk |
Ask every provider for an all-in monthly number for your exact headcount. If the quote shows only the license price, the real figure will be higher.
Setup Costs: Cabling, Network & Number Porting
Setup is where budgets get surprised. A phone system sends voice over your network, so the network has to be ready. Old Cat5 cable, an overloaded switch or weak Wi-Fi will cause choppy calls no matter how good the service is.
- Number porting: usually free to $10 per number, but plan a few business days for the carrier to finish.
- Network upgrade: a PoE switch often runs $300 to $1,500 for a small office.
- New cabling: typically $150 to $350 per drop, which matters in older Deep Ellum brick buildings with uneven wiring.
- Configuration: routing menus, voicemail and user setup may be $500 to $2,500 if billed separately.
- Training: some providers include it, others charge by the hour.
If your office also needs cabling work, a data cabling project can be scheduled together with the phone install to save a second visit.
A Power over Ethernet switch can run desk phones and access points from a single cable, which removes the need for separate power adapters.
Hardware: Desk Phones, Headsets & Softphones
Hardware is optional more often than people think. Many staff are happy with a laptop app and a good headset, which can cost $40 to $150 instead of a $150 desk phone. Reception, warehouse and shared spaces usually still want a physical handset.
| Device | Typical Price | Best For |
|---|---|---|
| Basic desk phone | $80 to $130 | Shared areas, light users |
| Mid-range desk phone | $130 to $220 | Everyday office staff |
| Executive or video phone | $250 to $450 | Managers, conference tables |
| Conference speakerphone | $200 to $600 | Meeting rooms |
| Wireless headset | $60 to $250 | Remote and hybrid staff |
| Softphone app | $0, included | Laptops and mobile phones |
Some providers rent phones for $3 to $8 per phone monthly. That lowers your up-front cost but usually costs more than buying outright after about two years.
Hosted vs. On-Premises vs. Teams Phone
The type of system changes both the price and where the money goes. Hosted systems lean on monthly fees. On-premises systems lean on up-front hardware. Teams Phone sits inside your Microsoft licensing and has its own math.
| Option | Up-Front Cost | Monthly Cost | Watch Out For |
|---|---|---|---|
| Hosted VoIP | Low | $20 to $45 per user | Fees add up with extra features |
| On-premises PBX | $5,000 to $30,000+ | Low, plus maintenance | Hardware refresh every 7 to 10 years |
| Microsoft Teams Phone | Low | $8 to $20 per user, plus calling plan | Needs the right Microsoft license |
| Hybrid or SIP trunk | Medium | $15 to $40 per user | Needs skilled setup & support |
If your staff already live in Microsoft 365, Microsoft Teams Phone can fold calling into tools they use daily. It can be cheaper, but only if your licenses and calling plan are priced correctly.
Softphone apps let staff on a laptop or mobile phone use the same business number without a desk handset.
Sample Budgets for 10, 25 & 50 Users
These examples use mid-range hosted pricing and include taxes. They are typical figures to help you plan, not quotes. Your own numbers will move with features and equipment.
| Office Size | One-Time Setup | Monthly Cost | Three-Year Total |
|---|---|---|---|
| 10 users, one office | $500 to $2,500 | $300 to $550 | $11,000 to $22,000 |
| 25 users, one office | $1,500 to $6,000 | $750 to $1,300 | $28,000 to $53,000 |
| 50 users, two sites | $4,000 to $15,000 | $1,500 to $2,600 | $58,000 to $108,000 |
A 10-person dental or accounting office in North Dallas might sit near the bottom of its row, using softphones and two reception handsets. A 50-person firm with a Downtown suite and a Plano branch will land higher, because of site-to-site networking, a call queue and recording for compliance.
Notice how monthly cost dominates over three years. That is why a slightly higher setup fee for better equipment or cabling can pay off if it prevents dropped calls and support tickets.
Hidden Costs & Quote Traps to Watch For
Most disappointment with phone pricing comes from items that were never in the first quote. These are the ones Dallas business owners tell us surprise them most often.
- Long contracts. Three- and five-year terms are common. Early termination fees can equal most of the remaining balance.
- Per-number charges. Direct lines, fax lines and extra locations each carry their own monthly fee.
- Overage minutes. Toll-free and international calling is often billed by the minute above an allowance.
- Feature tiers. Call recording or reporting may only exist on the top plan, forcing an upgrade for every user.
- Porting delays. If numbers do not move on schedule, you can pay two providers at once.
- Support fees. Adding or moving a user may cost a flat fee or an hourly rate.
Ask for the contract length, the early exit terms and a list of every fee in writing. If the provider hesitates, that tells you something.
How to Get a Fair Quote & Spend Less
Good pricing starts with good inputs. Before you call anyone, count your users, list who needs a desk phone, note how many numbers you keep and write down the features you truly use. A short list prevents you from paying for a premium plan you do not need.
- Ask for quotes in the same format so you can compare line by line.
- Check whether staff need the full license or only a basic one, such as for a shared lobby phone.
- Test call quality on your own network before you sign.
- Choose a term you are comfortable with, and ask about month-to-month options.
- Look at how your phone choice fits with the rest of your setup, for example your business phone system options and the network that carries them.
Saving money rarely means picking the cheapest plan. It means paying for what you use, avoiding surprise fees and buying equipment that lasts. A plan that costs $5 less per user but drops calls twice a week is not cheaper.
Comparing quotes line by line, with the same user count and features, is the fastest way to spot a hidden fee.
A phone system is one of those costs that looks simple until you read the fine print. The right price is the all-in number for your headcount, your equipment and your contract length. If a quote does not show all of that, ask for it. A fair provider will give you a clear, written figure without pressure.

FAQs
How much does a business phone system cost in Dallas?
Most hosted systems cost about $20 to $45 per user each month, plus any one-time setup. A 10-person office often spends $300 to $550 monthly. On-premises systems cost more up front, often $5,000 or higher, with lower monthly fees but ongoing maintenance and eventual hardware replacement.
Is VoIP cheaper than a traditional phone system?
Usually, yes. VoIP avoids the cost of an on-site PBX and old phone lines, and you pay per user instead. Savings depend on your equipment and contract. A large office with a recent on-premises system may find the gap smaller than expected.
Do I have to buy desk phones?
No. Many staff work well with a laptop or mobile app and a headset. Desk phones still make sense for reception, shared areas and anyone who dislikes headsets. Buying only the phones you need can cut setup cost noticeably.
What fees are not in the advertised price?
Taxes, E911 and regulatory fees often add 10 to 25 percent. Extra numbers, toll-free minutes, call recording and support charges may also be separate. Ask for an all-in monthly figure for your exact user count before you agree to anything.
How long does setup take?
Most small offices go live in one to three weeks. Number porting is usually the slowest step and can take several business days. Cabling or network upgrades add time, so schedule them early if your current network needs work.
Will my internet be good enough for VoIP?
Often yes, but test it first. Each call uses a small amount of bandwidth, but jitter and congestion matter more than speed. A business-grade connection, a decent router and a properly configured switch usually give clear calls.
Can I keep my existing phone numbers?
In most cases, yes. Numbers can be ported to a new provider, often for little or no charge. Keep your old service active until the port completes, or you risk missed calls and a gap in service.
Is a longer contract cheaper?
Sometimes. Three- and five-year terms can lower the monthly rate, but early exit fees can be steep. If you may move offices or change headcount, a shorter term or month-to-month plan can be worth a slightly higher price.
What happens to phones during a power or internet outage?
Hosted systems can forward calls to mobile phones automatically if your office loses power or internet. Set this up before you need it. Without it, callers may reach a dead line until service returns.
Should we choose Teams Phone or a standard VoIP service?
It depends on how your team works. Teams Phone suits firms already using Microsoft 365 heavily. A dedicated VoIP service may offer richer call handling and reporting. Compare total cost, including licenses and calling plans, not just the monthly phone fee.
