The best Mitel alternatives
Starting price$20/user/month
Free planNo
RingCentral is the leading Mitel alternative for enterprises wanting one all-in-one UCaaS suite. It combines phone, SMS, fax, video meetings, and team messaging with files and tasks, plus an app gallery of over 300 integrations. AI transcription and analytics sit across calls and meetings, and the platform is trusted by over 500,000 companies in published vendor claims.
Pricing is fully published: Core at $20, Advanced at $25, and Ultra at $35 per user per month billed annually, with monthly rates near $30, $35, and $45. The main watch item is SMS: Core allows 25 texts per user per month, Advanced 100, and Ultra 200, with overages after that, so text-heavy teams should price SMS honestly. Setup needs more configuration than simpler rivals, but teams that want one suite with deep controls get it here.
What we like- Phone, SMS, fax, video, and team messaging in one suite
- 300 plus integrations
- Strong AI transcription
- 99.999 percent uptime SLA
Watch out for- SMS capped at 25 per user per month on Core

Starting price$15/user/month
Free planNo
Nextiva suits multi-location teams that want reliable UCaaS tied to customer experience. It combines voice, SMS, routing, reporting, live chat, and customer journey tools, with built-in CRM features and contact management that reduce the need for a separate CRM. The visual call flow builder makes multi-location routing easy to set up without a telecom specialist.
Pricing starts at $15 per user per month billed annually on Core, with Engage near $50 and Power Suite CX near $75 in published comparisons, though some comparisons list Core at $23 monthly. SMS allowances run 100 to 500 per user per month depending on plan, which beats RingCentral Core for text-heavy teams. Support is rated highly, and the platform suits teams that want phone service tied to support workflows.
What we like- Lowest entry price tied here

Starting price$15/user/month
Free planNo
Dialpad fits sales and support teams that want built-in AI visibility into conversations. Real-time transcription, sentiment analysis, AI recaps, and coaching prompts run natively, without a separate AI add-on, which helps managers coach live calls. The interface is clean, and monthly billing is available for teams that dislike annual commitments.
Pricing starts at $15 per user per month billed annually on Standard, with monthly rates near $27, Pro at $25 billed annually or $35 monthly, and Enterprise on custom pricing. SMS limits vary by plan, so text-heavy teams should confirm caps in writing. Teams that prioritize AI features over the largest integration library will find Dialpad the most AI-native Mitel alternative.
What we like- Built-in AI transcription and summaries
- Real-time sentiment and coaching
- Clean interface
- Monthly billing available
Watch out for- Monthly rates higher than annual

#48x8
Best for: Global phone and contact center4.2/5 on
G2 (939 reviews, checked Oct 2026)
Visit 8x8.com
Starting price$24/user/month
Free planNo
8x8 suits global teams blending phone and contact center work. Unlimited calling reaches 14 countries on X2 and 48 countries on X4 in published comparisons, with unlimited texting and no monthly cap, which suits distributed teams that text heavily. The contact center is more mature than RingCentral equivalent in reviewer comparisons, and compliance coverage includes BAAs, FedRAMP Moderate, and PCI redaction.
Pricing is quote-only since public list prices were withdrawn in 2023, though published comparisons still cite $24 per user per month as a reference point and $15 to $44 ranges in broader guides. Native integrations number around 60, far fewer than RingCentral, and team chat is secondary to voice. Global teams should test international call quality during trial, since reliability varies by provider and region.
What we like- Unlimited calling to up to 48 countries on higher tiers
- Integrated contact center
- Strong compliance
- Simple admin
Watch out for- Public list prices withdrawn in 2023, now quote-based
- Around 60 native integrations
- Team chat secondary to voice
#5Vonage
Best for: Telephony plus APIs4.3/5 on
G2 (503 reviews, checked Oct 2026)
Visit vonage.com
Starting price$13.99/line/month
Free planNo
Vonage suits teams that want telephony plus communication APIs in one vendor. Voice, SMS, video, and verification APIs let developers build custom calling and messaging into apps, while the business phone plans cover standard office needs. Broad global calling and a customizable feature stack suit companies with varied requirements across locations.
Pricing starts at $13.99 per line per month in published comparisons, with Mobile near $17.99, Premium near $27.99, and Advanced near $37.99 in other comparisons, and some plans carry a one-year minimum. SMS allowances are estimated near 250 per user per month but vary, so confirm caps in writing. Teams without developers get less value from the API side, but API-driven companies will find Vonage the most flexible Mitel alternative.
What we like- Lowest per-line price here
- Extensive communication APIs
- Customizable feature stack
- Broad global calling
Watch out for- One-year minimum on some plans
- API setup needs developers
- SMS estimates vary
- Support quality mixed
#63CX
Best for: Self-hosted PBX4.4/5 on
G2 (548 reviews, checked Oct 2026)
Visit 3cx.com
Starting priceFree
Free planYes
3CX suits IT-led teams that want a self-hosted or self-managed PBX without per-user pricing. Paid plans charge by simultaneous calls rather than by user, which can save a lot for companies with many extensions but few concurrent calls. A free tier is available, and deployment can run on-premises or in the team's own cloud.
The trade-offs are expertise and support. 3CX needs IT staff to install, secure, and maintain it, and support runs through partners rather than a single vendor help desk. Cloud conveniences such as automatic updates and built-in redundancy need manual setup. Teams with IT capacity that want control and predictable costs will find 3CX the most independent Mitel alternative.
What we like- Free tier available
- Self-hosted or self-managed control
- Paid by simultaneous calls, not per user
- No per-user fees
Watch out for- Needs IT expertise to run
- Support depends on partners
- Fewer cloud conveniences
- Setup takes time
Starting price$30/user/month
Free planNo
Aircall suits support teams that need a big app-integration marketplace. It connects to CRMs, help desks, and sales tools, with call routing, analytics, and shared inbox features that help support and sales teams handle volume. The interface is clean, and setup is fast for cloud-first teams.
Pricing starts at $30 per user per month with a 3-seat minimum in published comparisons, with annual billing for the best rates. SMS allowances are estimated near 100 per user per month but vary, so confirm caps before signing. The entry price is higher than RingCentral or Nextiva, but teams that live inside their CRM and help desk will value the integration depth.
What we like- Big app-integration marketplace
- Clean support team workflows
- Call routing and analytics
- Good for sales and support
Watch out for- Higher entry price here
- 3-seat minimum
- Annual billing for best rates
- SMS estimates vary
#8GoTo Connect
Best for: Fast simple setup4.4/5 on
G2 (1,422 reviews, checked Oct 2026)
Visit goto.com
Starting price$26/user/month
Free planNo
GoTo Connect suits small businesses that want fast, simple setup without a telecom project. Cloud PBX, shared inbox, intelligent call routing, and call screening cover the core office phone needs, and the interface stays approachable for non-technical admins. Published comparisons list pricing near $26 per user per month, with ranges up to $80 on higher tiers and annual billing.
Some comparisons list GoTo Connect as contact sales, so teams should request a written quote for their user count. AI features are thinner than Dialpad, and the integration library is smaller than RingCentral. Small businesses that want a phone system live in days rather than weeks will find GoTo Connect a practical Mitel alternative.
What we like- Fast simple setup
- Cloud PBX
- Shared inbox
- Intelligent call routing
- Good for small businesses
Watch out for- Pricing varies by quote in some comparisons
- Fewer AI features than Dialpad
- Smaller integration library
How we chose
We compared Mitel alternatives on UCaaS breadth, AI features, international calling, SMS limits, pricing transparency, and fit for team size. Mitel deals run through partners and sales calls with no published list price, so we weighted published pricing heavily: if a vendor will not show the number, budgeting gets harder. Prices come from vendor pricing pages and published comparisons from 2026, and they change often, so confirm the current price before purchase.
How to choose the right Mitel alternative
Start with published pricing as the first filter, then check SMS and MMS limits in writing, since RingCentral Core allows only 25 texts per user per month and SMS overages have triggered platform switches on their own. Next, read contract terms and early termination fees before committing, and ask for SLA commitments on support response times in writing rather than marketing copy.
Next, map every integration: document each tool connected to Mitel, including CRM, help desk, and dialer tools, and confirm the new platform supports them natively or through an integration platform. For teams with offices outside the US, test call quality during trial, since international reliability varies widely across providers. Finally, trial with real call flows, including routing, voicemail, and SMS, before porting numbers.
