Microsoft Teams is a strong collaboration platform, but it is not automatically the best business phone system for every company.
The best Microsoft Teams Phone alternative depends on what your organization needs from calling. Small Google Workspace teams may want simplicity, sales teams may prioritize AI coaching, and support operations may need CRM context, omnichannel routing, and advanced reporting.
For most businesses that want a complete communications platform, our research has concluded that Nextiva is the best overall alternative to Microsoft Teams Phone. It combines business calling, messaging, video, customer context, contact center tools, AI capabilities, and 24/7 support. It can also integrate with Microsoft Teams, allowing companies to keep Teams chat, meetings, files, and Microsoft 365 while improving the phone system.
The best Microsoft Teams Phone alternatives for 2026 are:
Nextiva: Best overall for business calling, customer experience, contact center capabilities, and support in one platform.
Zoom Phone: Best for organizations that already use Zoom Meetings as their primary video platform.
Google Voice: Best for small, Google Workspace-first teams with straightforward calling needs.
Dialpad: Best for sales and support teams that want real-time transcription, summaries, and conversation intelligence.
Microsoft Teams Phone remains a good choice when a company already runs Microsoft 365, needs basic business calling, and wants employees to work in one familiar application. A dedicated alternative becomes more attractive when the business needs a phone-first mobile experience, deeper CRM integration, advanced contact center workflows, or more direct vendor support.
Microsoft currently lists Teams Phone Standard at $10 per user per month when paid annually. It is an add-on that requires an eligible Microsoft 365 plan or Teams license. Public calling also requires a PSTN connectivity model, such as a Microsoft Calling Plan, Operator Connect, or Direct Routing.
The real comparison should include:
Microsoft 365 licensing
Teams Phone and PSTN connectivity
International and toll-free calling
Recording and analytics
Desk phones and headsets
Contact center software
Implementation and administration
Use the Microsoft 365 pricing page for current licensing. Calling rates, product bundles, and enterprise agreements can change.
Teams Phone supports features such as auto attendants, call queues, voicemail, call forwarding, and external calling. A growing sales or support team may also need:
Skills-based routing and priority queues
Supervisor monitoring, coaching, whisper, and barge controls
Customer records displayed during a call
Inbound and outbound campaign tools
Quality management and conversation analytics
SMS, web chat, email, and social messaging
Service-level and workforce reporting
Some of these functions are available through additional Microsoft products, apps, or partners. A dedicated platform may provide more of them in one administrative environment.
Teams combines chat, channels, meetings, files, calendars, and calling. That works well for employees who use the full Microsoft ecosystem every day, but a receptionist, field employee, frontline worker, or salesperson may prefer a dedicated phone platform with a simpler desktop and mobile workflow.
Evaluate the complete operating model, not just the calling app.
Confirm support for business numbers, inbound and outbound calling, auto attendants, IVR, call queues, ring groups, voicemail, transfers, recording where permitted, and emergency calling.
Test practical tasks during a trial:
Can an administrator build a multi-level IVR?
Can a caller move to an overflow team after hours?
Can employees transfer calls between desktop and mobile?
Can users see availability before transferring a caller?
If customers call a sales or support team, compare contact center features rather than PBX checklists. Look for routing, supervisor controls, live and historical reporting, outbound dialing, customer history, quality management, and service-level metrics.
Omnichannel support deserves close review. A provider may list voice, SMS, chat, email, and social messaging but require separate products or licenses for each channel.
Microsoft Teams connects well to Microsoft 365, but it does not automatically become a CRM. Confirm how each alternative connects to Salesforce, HubSpot, Zendesk, ServiceNow, or another system of record.
The strongest integrations can:
Identify the caller before the agent answers
Open the correct customer record
Log calls and dispositions
Display previous interactions
Write notes or follow-up tasks back to the CRM
Compare what happens after a call is transcribed. Useful AI features may include summaries, action items, sentiment analysis, live agent assistance, keyword detection, and quality review. One of the top trending technologies is the popularity and adoption of AI voice agents.
AI voice agents such as XBert are one of the top ways companies handle incoming calls, engage with callers using natural language, capture leads, and offload the burden from front-desk receptionists.
Also ask for current uptime commitments, status history, incident procedures, emergency-calling processes, onboarding scope, and escalation channels. A vendor-reported uptime percentage isn't the same as an SLA, and an SLA doesn't guarantee perfect call quality on a poor local network.
Nextiva is the clear overall recommendation for businesses that want a complete communications and customer experience platform rather than a basic replacement dialer. It brings business voice, SMS, video meetings, team messaging, call routing, customer interactions, analytics, contact center capabilities, and AI tools into one product family.
Nextiva is especially strong for companies that want to keep Microsoft Teams for internal collaboration while improving customer-facing communication. Its official integrations directory lists Microsoft Teams, Outlook, Salesforce, HubSpot, Zendesk, ServiceNow, and other business applications.
Key strengths include:
Phone-first desktop and mobile access through NextivaONE
CRM and help desk connections that bring customer context into calls
Voice, SMS, chat, and contact center workflows in one environment
AI transcription, summaries, routing, and customer-journey tools on applicable plans
A path from business phone service to inbound or blended contact center operations
24/7 customer support across current plans
Nextiva’s pricing page currently lists these starting points when billed annually:
Nextiva delivers 99.999% uptime and proven historical track record of reliability. The main trade-off is price: higher tiers cost more than a phone-only service because they cover broader customer experience and contact center requirements.
For most organizations comparing Microsoft Teams Phone alternatives, Nextiva offers the strongest combination of capability, scalability, customer context, and support. It is the best overall choice in this comparison.
Zoom Phone is best suited to organizations that already rely on Zoom Meetings and want calling to fit naturally into that environment. Users can move between business calling, video meetings, team messaging, and collaboration without introducing another video platform.
Common Zoom Phone capabilities include:
Business numbers and cloud PBX functions
Call queues, auto attendants, transfers, and voicemail
Call recording and SMS in supported markets
Desktop and mobile calling
Handoffs between phone calls and Zoom Meetings
Administration through the broader Zoom Workplace environment
Zoom Phone’s main selection question is ecosystem fit. It is a strong candidate when the business already standardizes on Zoom or wants video meetings to sit at the center of its communications stack. Buyers should compare contact center depth, CRM workflows, international calling, analytics, and total Zoom Workplace costs alongside the phone plan.
Zoom offers different calling structures, including metered and unlimited options in supported markets. The right plan depends on domestic versus international calling, the number of occasional users, and whether the organization is buying Zoom Workplace at the same time. Request a quote that includes phone numbers, usage, recording, implementation, and any contact center requirements.
Zoom Phone is a focused, credible Teams Phone alternative. Its trade-off is that companies seeking a broader customer experience platform may need additional Zoom products, integrations, or a separate contact center solution.
Google Voice fits small businesses that already work in Gmail, Google Calendar, Google Meet, and Google Drive and need business calling without a large implementation project. Administration is familiar to Google Workspace users, and the service provides business numbers, voicemail transcription, call forwarding, mobile apps, and desk-phone support on applicable plans.
The higher tiers add more business telephony controls:
Automated attendants and ring groups
Call queuing
AI-generated call notes
Automatic call recording and transcription on Premier
Advanced reporting and Google data controls on Premier
Google currently lists Voice Starter at $10 per user per month, Standard at $20, and Premier at $30 for Workspace add-on plans. Review the current Google Voice plans because availability and plan details can change.
Google Voice also makes sense when the administrator wants to manage calling alongside existing Google Workspace users, groups, and permissions. Before choosing it, confirm regional number availability, international calling requirements, emergency-calling support, desk-phone needs, and the reporting controls required by managers.
Google Voice is a sensible fit when simplicity, Google Workspace integration, and predictable administration matter most. Companies with complex IVR, advanced supervisor controls, outbound campaigns, broad omnichannel support, or a full contact center should compare those requirements carefully before choosing a plan.
Dialpad is designed for businesses that want phone calls to produce usable operating data. Its main differentiator is conversation intelligence, including live transcription, summaries, action items, keyword tracking, sentiment analysis, and coaching features.
The platform also provides:
Business calling and messaging
Video meetings
Call routing and voicemail
Desktop and mobile applications
CRM and business-app integrations
Conversation analytics for sales, support, and quality teams
Dialpad is a strong option for sales managers, support leaders, and quality teams that want to analyze calls without manually reviewing every recording. Its best-fit question is whether AI-assisted conversations are the primary business requirement or one part of a wider customer experience strategy.
Pricing and feature availability vary by product and plan, especially for contact center, sales, support, and advanced analytics capabilities. Buyers should compare the required AI, CRM, support, and reporting features rather than judging the entry-level phone plan alone.
The evaluation should also cover transcription accuracy, supported languages, data retention, recording consent, CRM write-back, and whether summaries are available during or after a call. Those details determine how useful Dialpad’s AI is in day-to-day sales and service work.
Dialpad’s trade-off is scope, not capability. It is particularly well suited to conversation intelligence; organizations that need voice, digital messaging, customer journeys, contact center management, and customer records in one broader environment may prefer a platform such as Nextiva.
Before setting a cutover date:
Document phone numbers, extensions, toll-free services, queues, recordings, and after-hours rules.
Confirm number-porting requirements and authorization documents.
Map routing, holidays, overflow, failover, voicemail, and emergency-calling rules.
Validate E911 addresses and test emergency procedures where permitted.
Pilot desktop, mobile, headsets, desk phones, CRM integrations, transfers, and reporting.
Train employees on the new calling workflow and maintain a rollback plan.
Number-porting and routing errors usually create more disruption than installing a new app. Treat the project as a communications migration.
Microsoft Teams Phone is a good fit for straightforward calling inside a Microsoft-first environment. It becomes less compelling when the phone system also needs to function as a sales, support, and customer experience platform.
Nextiva is the best overall Microsoft Teams Phone alternative because it addresses the gaps that most often drive a search for another provider: customer context, contact center depth, omnichannel communication, AI-assisted workflows, phone-first access, and direct support. Its Microsoft Teams integration also makes the transition less disruptive. Businesses can keep Teams where it is strongest and use Nextiva to build a more capable business phone and customer communication system.
