A small healthcare practice replacing its phone system should budget for more than the monthly telephone service. A complete replacement may involve recurring user or extension fees, desk phones, installation, network upgrades, number porting, staff training, and ongoing support.

For a practice with 10 to 25 employees, the total cost depends on how many employees need phone access, how many calls the practice handles, whether existing equipment can be reused, and which services are included in the vendor's proposal.

The most useful approach is to compare initial implementation costs, ongoing monthly expenses, and total cost of ownership over three to five years. This provides a more realistic budget than comparing advertised monthly prices alone.

What Costs Should a Healthcare Practice Expect When Replacing Its Phone System?

A replacement budget generally has two components: one-time expenses to implement the new system and recurring expenses to operate and support it.

The following categories should be included when requesting proposals.

Cost Category	Typical Expense Type	What It Covers
Phone service and licensing	Recurring	Users, extensions, calling plans, and included services
Desk phones and accessories	One-time or financed	Physical telephones, headsets, and related equipment
Installation and configuration	One-time	System setup, call routing, voicemail, and initial testing
Number porting	Usually one-time	Transferring existing telephone numbers
Network and internet upgrades	One-time and potentially recurring	Connectivity, switching, cabling, and power requirements
Staff training	One-time or recurring	Teaching employees how to use and administer the system
Support and maintenance	Recurring	Technical assistance, updates, and equipment support
Additional services	Varies	Optional features, integrations, and usage-based charges

Not every practice will incur every expense. Some vendors bundle equipment, implementation, and support into a subscription, while others charge separately.

The important question is not simply what the vendor charges each month, but what the practice must spend to make the new system operational and keep it working reliably.

How Much Does Monthly Phone Service Cost?

For a small healthcare practice, cloud-based business phone subscriptions commonly start around $15 to $30 per user per month for standard service, with higher-tier plans costing more.

For example, published business phone pricing from Zoom, Nextiva, and RingCentral includes entry-level offerings around $15 to $20 per user per month, depending on the vendor, plan, and billing commitment. These are general business offerings, not necessarily complete healthcare-ready solutions.

For initial budgeting, a practice might evaluate a planning range of $20 to $40 per licensed user per month. This is an illustrative budgeting range, not a guaranteed market rate or vendor quote.

Licensed Users	At $20/User/Month	At $40/User/Month
5	$100	$200
10	$200	$400
15	$300	$600
20	$400	$800
25	$500	$1,000

These figures cover subscription charges only. They exclude equipment, implementation, taxes, regulatory fees, optional services, and separately billed support.

Does Every Employee Need a Paid Phone License?

Not necessarily.

A 20-employee practice might have only 12 employees who regularly answer or place calls. Other employees may use shared telephones, common-area extensions, or alternative arrangements.

However, some vendors require licenses for shared devices, specific calling capabilities, or other configurations.

Before estimating monthly costs, determine:

• How many employees need individual telephone accounts?
• How many shared phones are required?
• Which employees need to make and receive calls outside the office?
• Are reception, scheduling, and billing departments using shared or individual extensions?
• Do common-area phones require separate licenses?
• Are additional numbers or specialized services billed separately?

A licensing review can prevent a practice from paying for unnecessary accounts while ensuring employees have the access they need.

How Do Different Pricing Models Affect the Budget?

Phone vendors may structure their charges differently.

Per-user subscriptions: Each licensed employee receives access to specified calling services. This is common with cloud-based business phone platforms.

Per-device or per-extension pricing: Charges depend on physical phones, extensions, or assigned endpoints.

Usage-based pricing: Some services charge for calling minutes, certain destinations, or other measured usage.

Bundled service agreements: Equipment, calling services, installation, and support may be combined into one recurring payment.

On-premises systems: These may require a larger initial equipment investment, along with ongoing telephone connectivity, licensing, maintenance, and support.

The lowest advertised monthly rate is not necessarily the lowest total cost. A practice should compare what each pricing model includes before choosing one.

What One-Time Expenses Should Be Included in the Replacement Budget?

Recurring subscriptions are only part of the investment. Several one-time expenses can materially change the cost of replacing an existing system.

1. Desk Phones, Headsets, and Other Equipment

A practice may need physical telephones for reception, scheduling, billing, physician offices, and other work areas.

Potential equipment expenses include:

• Desk phones
• Receptionist or attendant consoles
• Wireless headsets
• Conference-room phones
• Power adapters
• Network switches
• Cabling
• Battery backup equipment

Some employees may be able to use a supported computer or smartphone application instead of a dedicated desk phone.

Existing phones may also be reusable, but only if the new vendor supports the exact models and required firmware.

Do not assume that a phone supporting Voice over Internet Protocol (VoIP) will work with every VoIP provider.

2. Installation and System Configuration

A new phone system must be configured to support the practice's operations.

Installation may involve creating employee accounts, assigning telephone numbers, configuring extensions, establishing call routing, recording greetings, and testing inbound and outbound calls.

For healthcare practices, particular attention should be given to how calls reach reception, scheduling, billing, and clinical staff.

The proposal should identify whether installation is included, remotely delivered, or billed as a separate professional service.

3. Network and Internet Readiness

Cloud-based phone systems depend on reliable network and internet connectivity.

A practice may need to improve its network before deploying new phones, particularly if the existing infrastructure is older or already experiences performance problems.

Potential expenses include upgrading switches, installing additional network cabling, configuring traffic prioritization, or adding battery backup protection.

A secondary internet connection may also be worth evaluating when telephone availability is essential to practice operations.

These expenses should not automatically be attributed entirely to the phone system if the upgrades also support other business technology. However, they still affect the cash required to complete the project.

4. Number Porting and Service Transition

Most practices want to retain their established telephone numbers.

The Federal Communications Commission recognizes number portability between traditional telephone, wireless, and interconnected VoIP providers, subject to applicable requirements.

However, retaining a number does not mean the transition requires no planning.

A practice should confirm:

• Which existing numbers can be transferred
• Whether the vendor charges porting fees
• How long the transfer is expected to take
• Whether the current provider imposes termination charges
• Who coordinates the transfer
• How calls will be handled during the transition
• Whether fax, alarm, elevator, or other specialty lines require separate arrangements

Number porting can take several business days or longer, depending on the numbers, providers, and complexity of the transfer.

Do not cancel the existing telephone service before the numbers have been successfully transferred and tested.

A poorly coordinated transition could interrupt patient calls or leave important numbers temporarily unavailable.

5. Employee Training and Administrative Setup

Employees need to understand how to use the new system before the old one is disconnected.

Training should address the workflows relevant to each employee's responsibilities.

Reception staff may need to learn how to transfer calls, manage multiple incoming calls, and route callers to the appropriate department.

Other employees may primarily need to understand voicemail, call forwarding, and mobile access.

The Practice Administrator or designated employee should also know how to request account changes, update greetings, and obtain support.

Training may be included in the implementation price or billed separately.

How Much Could a Complete Phone System Replacement Cost?

The following hypothetical example illustrates how a small healthcare practice can build a realistic replacement budget.

Example: A 15-Employee Houston Medical Practice

Consider an independent medical practice with 15 employees.

The practice has one location, an existing telephone system, and a combination of reception, administrative, and clinical employees.

After reviewing its needs, the practice determines that it requires:

• 12 licensed phone users
• 8 new desk phones
• Retention of its existing telephone numbers
• Initial configuration and call-routing setup
• Employee training
• Minor network improvements

For illustration, assume the following expenses.

Cost Category	Hypothetical Cost
8 desk phones at $150 each	$1,200
Installation and configuration	$1,000
Number porting and transition	$200
Employee training	$300
Network improvements	$500
Total one-time expenses	$3,200
12 licenses at $30/month	$360/month
Additional recurring services and support	$100/month
Total recurring expenses	$460/month

These figures are hypothetical planning assumptions, not actual ResTech pricing, vendor quotations, or verified industry averages.

What Would the Practice Spend Over Five Years?

Assuming the monthly charges remain unchanged and no additional equipment replacements or major upgrades are required:

• One-time implementation: $3,200
• Five years of recurring service: $460 × 60 = $27,600
• Five-year total cost: $30,800

That is equivalent to approximately $513 per month when the initial investment is spread across 60 months.

The example demonstrates why the monthly subscription alone does not represent the complete cost.

A practice evaluating competing proposals should perform the same calculation for each option.

How Should a Healthcare Practice Calculate Total Cost of Ownership?

Total cost of ownership (TCO) measures what the phone system is expected to cost over a defined period, including both implementation and ongoing expenses.

A simple calculation is:

TCO = One-Time Costs + (Monthly Recurring Costs × Number of Months) + Additional Expected Expenses

For a three-year comparison, multiply monthly recurring charges by 36. For a five-year comparison, multiply them by 60.

The calculation should also account for expenses that may not appear in the initial proposal, including equipment replacement, contract increases, support exclusions, and expected changes in licensing.

Example: Comparing Two Phone System Proposals

Consider the same 15-employee healthcare practice evaluating two competing proposals.

Vendor A has a lower monthly subscription but higher installation costs.

Vendor B charges more each month but includes more of the initial implementation expenses.

Cost Category	Vendor A	Vendor B
One-time implementation	$4,500	$1,500
Monthly recurring charges	$400	$475
Three-year recurring costs	$14,400	$17,100
Three-year total	$18,900	$18,600
Five-year recurring costs	$24,000	$28,500
Five-year total	$28,500	$30,000

These are hypothetical figures used to demonstrate the calculation, not actual vendor quotes.

Over three years, Vendor B is $300 less expensive despite having a higher monthly rate.

Over five years, Vendor A becomes $1,500 less expensive because its lower recurring charges eventually offset the larger initial investment.

This example assumes fixed monthly rates and excludes additional costs not shown in the table.

The comparison demonstrates why the expected ownership period matters. A practice planning to keep a system for five years may reach a different financial conclusion than one expecting to change systems within three years.

Cost should not be the only consideration. The practice must also confirm that each proposal meets its operational requirements and includes appropriate implementation and support responsibilities.

What Additional Costs Can Make a Phone System More Expensive Than Expected?

Some of the most important budget differences become apparent only after the practice reviews the contract and implementation scope.

Support and Maintenance Exclusions

A vendor may include basic telephone service support but charge separately for changes to call routing, onsite troubleshooting, equipment replacement, or assistance with the local network.

Determine who handles each type of problem and whether the practice's existing IT Service Provider will have additional responsibilities.

Contract Terms and Price Increases

Some advertised rates require annual billing or multiyear commitments.

Before signing, confirm the contract length, renewal terms, price-adjustment provisions, cancellation charges, and any remaining equipment obligations.

A low introductory rate can become less attractive if it increases substantially after the initial term.

Specialized Healthcare Requirements

Healthcare practices may need additional safeguards for voicemail, call recordings, messages, and other information containing protected health information.

When a phone vendor creates, receives, maintains, or transmits protected health information on behalf of a covered entity in a manner that makes it a business associate, an appropriate Business Associate Agreement (BAA) is required.

The U.S. Department of Health and Human Services explains that cloud providers maintaining electronic protected health information on behalf of covered entities generally qualify as business associates, even when the information is encrypted.

The practice should verify the vendor's responsibilities, available safeguards, and contractual arrangements rather than assuming that a general business phone subscription is automatically appropriate for healthcare use.

These requirements may affect which service tier or vendor can be selected.

Transition and Downtime Planning

The practice should also budget for coordinating the changeover.

A replacement should include testing of inbound calls, outbound calls, voicemail, call routing, and emergency calling before the system is considered operational.

Where practical, schedule the transition outside peak patient-call periods and establish a contingency procedure if calls do not route correctly.

The financial impact of missed calls or an unsuccessful transition may exceed the cost of the implementation itself.

What Should a Practice Request Before Approving a Phone System Proposal?

Before signing an agreement, the Practice Administrator should request a written breakdown that answers these questions:

1. Initial cost: What equipment, installation, network work, number porting, and training expenses are required?
2. Monthly cost: How many licenses are needed, and what recurring charges apply?
3. Included services: Which calling capabilities, administrative functions, and support services are included?
4. Additional charges: What costs extra, including optional services, usage charges, taxes, and regulatory fees?
5. Existing equipment: Can any current phones or supporting infrastructure be reused?
6. Healthcare requirements: How will patient information be protected, and what contractual safeguards are available?
7. Implementation: Who coordinates number transfers, system configuration, testing, and staff training?
8. Ongoing support: Who is responsible when the problem involves the phone vendor, internet provider, or local network?
9. Contract obligations: What happens if the practice needs to add users, remove users, or change providers?
10. Total ownership cost: What is the expected expense over three to five years?

Comparing vendors using the same questions makes it easier to identify differences that advertised monthly prices may conceal.

Frequently Asked Questions

Is a Cloud-Based Phone System Usually Cheaper Than an On-Premises System?

A cloud-based phone system often requires less initial infrastructure investment, but it is not automatically less expensive over time.

An on-premises system may require equipment purchases, licensing, maintenance, and support, while a cloud-based system generally relies more heavily on recurring subscriptions.

Compare both options over the same three- to five-year period.

Can a Healthcare Practice Keep Its Existing Telephone Numbers?

Generally, yes. Many telephone numbers can be transferred between providers through number porting.

However, the practice should confirm that every important number is eligible for transfer and coordinate the transition before canceling existing services.

Does a Practice Need to Replace Every Desk Phone?

Not always.

Some existing phones may be compatible with the new system. Other employees may be able to use supported computer or mobile applications.

Compatibility should be verified with the new vendor before assuming equipment can be reused.

How Long Does It Take to Replace a Small Practice's Phone System?

The timeline depends on equipment availability, network readiness, configuration complexity, and telephone number transfers.

A straightforward installation may require relatively little onsite work, but number porting and vendor coordination can extend the overall project to several weeks.

The practice should obtain a written implementation schedule rather than relying on a general estimate.

Can a Healthcare Practice Replace Its Phone System Without Interrupting Patient Calls?

A carefully planned transition can reduce disruption, but no provider should guarantee that interruptions are impossible.

Testing, number-porting coordination, contingency routing, and scheduling the cutover during a lower-volume period can help reduce the risk.

Does the Monthly Phone Subscription Include IT Support?

Not necessarily.

The telephone vendor may support its application and calling platform, while the practice's IT Service Provider handles local networking, connectivity, workstations, and related infrastructure.

The agreement should clearly identify which provider is responsible for each area.

Final Thoughts

Replacing a phone system is both a communications decision and a technology investment.

For a small healthcare practice, the most useful budget is one that accounts for initial installation, ongoing subscriptions, equipment, support, and the cost of maintaining reliable communications over several years.

Before committing to a replacement, compare complete proposals rather than advertised monthly prices.

A slightly more expensive system may provide better overall value if it reduces implementation problems, includes necessary support, and meets the practice's operational and security requirements.
