Microsoft Teams Phone vs Nextiva: Which Fits Your Business in 2026?
Microsoft Teams Phone puts external calling into a Microsoft collaboration workflow. Nextiva brings phone, business messaging and customer communication tools into its own platform. Both deserve consideration if you run a service business, but the decision depends on what happens after a customer calls, texts or waits in a queue.
There is a third configuration to evaluate: Nextiva also offers business calling through Teams using Direct Routing, subject to a specific Microsoft license and Nextiva voice service.

Teams Phone fits organizations where Teams is already the staff hub and the IT team can manage phone licenses plus a carrier path.
Nextiva deserves a closer look if inbound calls, business texting, routing and customer follow-up are the buying priority.
Price Nextiva Core, Engage and any separate contact-center tools against the features you actually need.
What Is the Main Difference?
Teams Phone supplies a cloud PBX inside Microsoft Teams and needs an eligible connection to public telephone numbers. Nextiva sells a business communications suite with phone, SMS and other channels, with capabilities that change by plan. Nextiva can also provide calling in Teams through its separate Direct Routing integration. Decide whether your staff should handle customer calls in Teams or in Nextiva's own service workflow.

Call Quality, Scale, Integrations and Customer Follow-Up
Call quality
Test both on the same office connection, devices and destinations. Network congestion, headset choice and carrier route can affect calls on either platform.
Call routing
Build your real main-number greeting, after-hours rule, overflow and voicemail. Compare queues and how quickly a manager can make a change.
Scalability
Add a sample employee, location and number. Verify country availability and administrator roles before planning a multi-site rollout.
Integrations
Teams Phone naturally fits Microsoft 365. Nextiva offers customer communication workflows; verify the specific CRM, help-desk and Teams integration in your plan.
Customer history
Walk from missed call to voicemail to SMS follow-up. Check whether the same agents can see the full interaction and whether that requires Engage or other tools.
Reporting
Compare missed-call, queue and response-time dashboards. Ask for a live view of the exact reports your service manager needs weekly.
Can You Keep Teams and Buy Nextiva Calling?
Yes. Nextiva's Business Phone for Teams page describes Direct Routing that allows calls inside the Teams interface while Nextiva provides the calling service. Nextiva lists an active voice account and a compatible Microsoft 365 license among its requirements; its examples include E5 or E3 with a Phone add-on for certain configurations. Confirm the exact license combination, countries and integration architecture with the provider.
1. Teams Phone
Microsoft phone system with Microsoft Calling Plan or another eligible PSTN path. Staff call from Teams.
2. Nextiva independently
Use Nextiva's own apps for phone, SMS and the customer communication tools available on the selected plan.
3. Nextiva in Teams
Use Nextiva's Direct Routing service with a compatible Microsoft calling license. Request a written map of licensing and support ownership.
Buying tip: Ask the demo team to transfer a call, receive a customer text and show customer history on the proposed configuration. “Works with Teams” does not specify which functions are included or where they appear.

What Two Published Deployments Teach Us
Microsoft Teams Phone: ScottMadden
In Microsoft's customer account, ScottMadden describes moving phone calling into a familiar Microsoft environment and guiding staff through adoption. The transferable lesson is to plan user training with the number migration. This is a vendor-published example.
Nextiva: Reliance Partners
Nextiva's Reliance Partners story describes an insurance business using a phone tree, routing and analytics to manage a high call volume. The lesson: test the real customer path through departments and measure missed or delayed responses. Its results reflect that company's own deployment, not a guaranteed outcome.

Teams Phone vs Nextiva: Frequently Asked Questions
Is Teams Phone included in Microsoft Teams?
The base Teams app does not automatically include the full public telephone service. Check your Microsoft 365 or Teams license, Teams Phone entitlement and chosen PSTN connection.
Does Nextiva replace Microsoft 365?
No. Nextiva provides business communications and customer interaction products; it does not replace Microsoft 365 productivity apps such as Word, Excel and SharePoint.
Does Nextiva work with Microsoft Teams?
Nextiva advertises Business Phone for Teams using Direct Routing. Its published requirements include an active Nextiva voice account and an eligible Microsoft 365 license with calling capabilities. Confirm the exact Microsoft and Nextiva license combination in writing.
What does Nextiva Core include?
Its US pricing page lists inbound and outbound voice, business SMS, video meetings, screen and file sharing, call routing, team chat and mobile access in Core. Verify usage allowances and current terms.
Are live chat and inbound call-center tools in Nextiva Core?
The Nextiva pricing page currently lists live chat, chatbot, advanced reporting and an inbound call center under Engage rather than Core. Check the detailed entitlement list and quote.
Which is cheaper?
Compare the same number of users, country coverage and calling volume. Teams Phone may require separate Teams and PSTN costs; Nextiva bundles and promotional prices can vary by term, plan and add-ons.
Can I port my existing business numbers?
Porting depends on number type, location and current carrier. Have the provider confirm eligibility and schedule before cancelling old service.
How do I test call quality?
Place comparable calls on each service over your actual office and mobile networks, and log delays, dropped calls, one-way audio and transfer issues.
Do either of these replace a contact center?
Basic phone queues are not a substitute for every contact-center feature. Scope digital channels, agent reporting, quality management and workforce tools separately.
Final Verdict
Teams Phone is the natural short list if Teams is your operating environment and you can plan its license and PSTN requirements. Nextiva is compelling when customer calls, texts and service follow-up need to sit closer together. Price the right Nextiva tier, then demo the exact missed-call-to-follow-up workflow. If employees must stay in Teams, request a separate quote for Nextiva Direct Routing.
