A phone quote should tell you what it costs to keep customers connected to your team. The advertised subscription is one part of that cost. Installation, calling service, equipment, training, and ongoing support determine what the complete system will cost your business.
The short answer: compare the complete cost
Published cloud phone subscriptions can give you a starting point. As checked on September 9, 2026, Nextiva lists Core at $15 and Engage at $25 per user per month with annual billing. Ooma Office lists Essentials at $19.95, Pro at $24.95, and Pro Plus at $29.95 per user per month. These are selected vendor examples with different features and terms, not a survey of what Tulsa businesses pay.

NSN installs and supports 3CX phone systems. Its annual system license is sized by simultaneous call capacity and user or extension limits. A complete NSN proposal also accounts for hosting, calling service, equipment, implementation, and agreed support.
Understand what each quote is charging for
| Quote type | How it works | What to check |
|---|---|---|
| Per-user subscription | A monthly or annual subscription for the billed users or lines. | Included calling, plan features, shared-device pricing, add-ons, and contract terms. Some plans include unlimited domestic calling. |
| 3CX system license | An annual license with simultaneous call capacity and a user or extension limit for the chosen tier. | Both limits, edition, hosting, calling service, installation, and support. The license price alone is not the complete phone bill. |
| Existing on-premises system | A deployment choice that may include owned equipment, licensing, maintenance, and separate phone service. | Remaining equipment life, support availability, service costs, replacement costs, and required features. NSN deploys new systems in the cloud. |
For 3CX, use actual call activity and the full user and extension inventory to size the system. Headcount alone does not establish peak call demand. See 3CX’s current licensing tiers for call capacity, user limits, and edition pricing. Adding an extension within a license may avoid a license upgrade; devices, setup, calling, or support charges can still apply.
Build a budget that includes implementation and support
| Line item | What to ask |
|---|---|
| License and hosting | Which edition and limits are quoted? Is hosting included? What would trigger an upgrade? |
| Calling service | Which numbers, destinations, minutes, and services are included? What are the overage and international rates? NSN quotes calling service as its own line item. |
| Phones and accessories | Which existing handsets are supported and reusable? Who needs a desk phone, headset, mobile app, or shared phone? Are devices purchased or rented? |
| Setup and number porting | Who verifies number eligibility, handles paperwork, builds call routing and greetings, tests the cutover, and trains staff? |
| Network work | Does the proposal include agreed firewall, switching, or connectivity changes? Who handles new cable runs? Read our guide to network issues that affect call quality. |
| Features and storage | Are queues, recording, reporting, messaging, and integrations in the selected edition? What costs apply to connected services or recording storage? |
| Ongoing support | Who handles configuration changes, troubleshooting, updates, and carrier coordination? What are the coverage hours and exclusions? |
| Taxes, fees, and contract terms | What is the estimated total with applicable taxes and fees? Check renewal pricing, cancellation terms, number transfer, and existing contract exit costs. |
A worked example: turn the monthly rate into an annual budget
Suppose a proposal bills 30 users at $25 per user per month. That is $750 per month, or $9,000 per year, for that subscription line. This is hypothetical arithmetic, not an NSN quote or a client case study. Whether a shared phone counts as a full billed user depends on the plan.
| Budget line | Per-user example | 3CX proposal |
|---|---|---|
| Annual base subscription | 30 billed users × $25 × 12 = $9,000 | Quoted annual system license, sized for calls and users |
| Recurring services | Add anything outside the plan: support, calling, storage, or other services | Add quoted hosting, calling service, agreed support, and connected services |
| One-time costs | Equipment, installation, training, and any contract exit costs | Equipment, installation, training, and any contract exit costs |
| Taxes and fees | Use the provider’s estimate for your services and locations | Use the estimate supplied with your proposal |
Compare the first-year total and the ongoing annual total separately. Savings cannot be calculated until both proposals cover the same business requirements.
Include 911 configuration and recording decisions
Have the provider explain direct 911 dialing, notifications, location information, and the process for keeping those records current as people move. Review the FCC guidance on multi-line telephone systems with the provider when defining the configuration.
If you need recording or transcription, specify who can access the records, where they are stored, and how long they are retained. These decisions can affect the edition, storage, connected services, and implementation work in the proposal.
How to compare two phone quotes fairly
- Use the same inventory: users, shared devices, locations, phone numbers, and actual call demand.
- Match the features you need: call flows, queues, mobility, recording, reporting, and integrations.
- Compare implementation: number transfer, testing, training, network work, and a planned cutover.
- Put support in writing: responsibilities, coverage, routine changes, and how issues are handled.
- Compare complete annual totals: recurring charges, one-time work, taxes, renewal pricing, and exit costs.

Questions Tulsa businesses ask about this
How much should a Tulsa business budget for a phone system?
Start with users, call demand, locations, and features. Compare a complete first-year and ongoing annual total covering subscriptions, hosting, calling, equipment, installation, training, support, taxes, and fees. Published per-user prices alone do not establish the cost of a fully implemented system.
What would 30 users cost on a $25 monthly plan?
The base subscription would be $750 per month or $9,000 per year, before anything excluded from the plan. This is a hypothetical calculation, not an NSN quote. Check whether shared devices are billed as full users and add the actual implementation and service costs.
Is 3CX always cheaper than a per-user phone plan?
No. 3CX has annual system licensing with simultaneous call capacity and user or extension limits. Total cost also includes hosting, calling service, equipment, implementation, and support. Savings depend on the complete proposals and your requirements.
Are additional 3CX extensions free?
An extension may fit within the current license without an upgrade. Call capacity, user or extension limits, devices, calling usage, and setup or support work still need checking.
What should be included in a phone-system quote?
Look for the license or subscription, hosting, calling service, number porting, equipment, call-flow configuration, training, network work, ongoing support, taxes, fees, and contract terms. Identify one-time costs separately from recurring charges.
Can we reuse our phone numbers and handsets?
NSN checks number-porting eligibility and handset compatibility before committing to a migration plan. Access, carrier records, hardware models, and device restrictions affect what can be reused.
How long does a phone-system migration take?
The schedule depends on number porting, account access, locations, call-flow complexity, and network work. NSN agrees a plan after reviewing those dependencies and coordinates configuration, training, cutover, and testing.
Can NSN review the cost of an existing 3CX system?
Yes. NSN reviews the license, hosting, calling service, users, call flows, and agreed support requirements. A recent invoice and details of the current setup help establish a useful comparison.
Does NSN publish a standard phone-system price?
NSN prepares a proposal after reviewing your requirements. It identifies the system, calling service, implementation, and ongoing support. The published vendor examples in this guide are not NSN prices.
