If you are searching for metaswitch alternatives, you’re probably not looking for “a new vendor” in the abstract. You’re looking for a path forward that keeps your customer base stable, protects your margins, and gives you a modern offer you can sell this quarter.
This article is written for Metaswitch dealers in the real world: MSPs, agents, and service providers who have sold (or supported) Metaswitch-based voice, and now want a cleaner landing spot that’s built for resale.
TL;DR
Metaswitch has changed hands twice in recent years: acquired by Microsoft in 2020, then acquired by Alianza from Microsoft, with the deal completed in 2025.
For “dealers,” the practical question is usually not “what Class 5 switch replaces Metaswitch?” It’s “what platform lets me keep selling voice under my brand with less operational pain?”
Most alternatives fall into four buckets: stay on Metaswitch (now under Alianza), rebuild your own stack, move to another wholesale UCaaS platform, or migrate to a reseller-first platform like Viirtue.
Viirtue is designed for resale: white-label, quote-to-cash, usage rating, telecom tax automation, and sellable AI (agents + call insights).
If you want to win in 2026, the biggest differentiator is not dial tone. It’s the business layer: quoting, billing, taxes, onboarding speed, and AI features customers will pay for.
Metaswitch alternatives: what changed and why dealers are re-evaluating
For most Metaswitch dealers, the best “Metaswitch alternatives” are not other carrier softswitches. They are resale platforms that let you deliver a modern voice + UCaaS experience under your brand, with quoting and billing that scale. The right alternative depends on whether you are operating carrier infrastructure or reselling a hosted offer.
What changed in the Metaswitch ecosystem
Metaswitch is no longer in the same ownership context it was a few years ago:
Microsoft announced the agreement to acquire Metaswitch Networks in 2020 and later updated that the acquisition was completed.
Alianza announced a definitive agreement to acquire Metaswitch from Microsoft in December 2024 and then announced the acquisition’s completion in March 2025.
Metaswitch’s own website now positions the products as part of Alianza’s portfolio (“Now part of Alianza”).
If you’re a dealer, that does not automatically mean “panic.” It does mean you should reassess:
product roadmap certainty,
partner enablement,
and whether your current platform helps you sell faster or makes you carry operational debt.
The market tailwind dealers should not ignore
If you are building your next voice offer, it helps to zoom out: Zion Market Research estimates the global VoIP market at USD 42.97B in 2023, projecting growth to USD 105.13B by 2032.
That growth attracts competition, which raises the bar on onboarding experience, analytics, and AI features buyers now expect.
Metaswitch alternatives dealers can actually execute
The four real paths (and who they fit)
Most dealer situations map to one of these:
Stay in the Metaswitch ecosystem (now under Alianza): Best when your business model is deeply tied to Metaswitch products and your upstream path is stable. Alianza has publicly stated it will continue to support Metaswitch offerings while integrating into a unified portfolio.
Move to another wholesale UCaaS platform: Best when you want a new hosted voice foundation without running carrier-grade infrastructure yourself. The tradeoff is that many “UCaaS-first” platforms still leave you stitching together quoting, taxes, usage, and onboarding.
Build and operate your own stack: Best when you are truly a facilities-based provider with an engineering team that wants full control. The tradeoff is time, cost, and ongoing staffing.
Land on a reseller-first platform built for MSP motion (Viirtue): Best when your priority is speed-to-market, brand ownership, and scaling billing, onboarding, and AI without building internal software.

What most “Metaswitch alternative” articles miss
Most discussions focus on the technology layer (softswitch vs softswitch). Dealers usually win or lose on the operating layer: quoting speed, invoice accuracy, taxes, and how quickly customers can go live without escalations. That is where most margin leakage happens.
Why Viirtue is a perfect landing spot for Metaswitch dealers
1) You get a resale-first foundation: white label + cloud voice
If you’re a dealer, your customer should see you, not your upstream. Viirtue’s white label VoIP partner model is built around that, including brandable portals and billing, and it positions margins “up to” a stated level depending on how you price and package.
If your current Metaswitch-based offer was “voice service plus a lot of manual back office,” that’s the gap you can close immediately.
2) The real unlock: quote-to-cash that dealers do not have to build
This is where most migrations fail: a dealer changes the platform but keeps the same broken back office.
Viirtue’s quote-to-cash layer (ViiBE) is positioned as native to the platform, including quoting, billing, and tax handling without bolting on separate systems.
Practical dealer value:
Faster proposals with quoting built for voice packaging
Automated recurring invoicing through telecom billing
Rated usage billing via usage rating ,so you can charge correctly when usage varies
Less invoice drama via telecom tax automation
3) A modern differentiator you can sell: AI voice agents + AI insights
Metaswitch dealers often have a solid “phone system” offer already. The question is how to upsell something buyers will pay for.
Viirtue productizes AI as reseller SKUs:
AI voice agents that handle calls and execute tasks
AI Insights (summaries + sentiment indicators) to improve visibility into call outcomes
This matters because “we have voice” is no longer a premium pitch. “We reduce missed calls and turn conversations into measurable outcomes” is still true.
4) Teams-first path for dealers who sell Microsoft 365 every day
If your dealer base is already selling Microsoft 365, you can also package voice where the user already lives.
Viirtue promotes a Microsoft Teams calling offer under your brand, and positions it as Teams plus optional softphones with white-label billing and quoting supported by ViiBE.
5) Migration playbook: what to do first (and what not to do)
Here’s the dealer-friendly migration sequence that reduces churn:
Step 1: Inventory your “Metaswitch-era” packaging
seats, DIDs, hunt groups, call queues, voicemail, e911
any “hidden” add-ons that are revenue-critical (recording, analytics)
Step 2: Build your new SKUs and bundles
lock pricing, taxes, and invoice structure before you migrate customers
do not “figure it out later” because later becomes credits, disputes, and churn
Step 3: Create a porting plan by customer segment
single-site SMBs first, multi-location later
pre-validate account data and port timing
Viirtue has published a reseller-oriented guide to number porting that covers common timing expectations and pitfalls.
Step 4: Upgrade your enablement, not just your platform
Most dealers underinvest here. Viirtue provides partner-facing marketing templates integrated into Canva-style workflows so your brand can look enterprise-grade without hiring a full design team.
6) Compliance note (keep it simple)
If you’re originating PSTN traffic, compliance topics like STIR/SHAKEN and robocall mitigation can apply depending on your model. Informational only, not legal advice. If you want a dealer-focused explainer, Viirtue has a guide on STIR/SHAKEN and the Robocall Mitigation Database requirements.
Next steps for Metaswitch alternatives
If you are actively evaluating Metaswitch alternatives, the smartest next step is to stop framing this as a softswitch replacement and start treating it as a resale and revenue upgrade. The right move is a platform that supports white-label VoIP, simplifies quote-to-cash, and removes friction from usage billing and telecom tax automation so you can migrate customers without margin erosion.
For dealers who want to keep selling under their own brand while modernizing their offer with AI voice agents, AI call insights, and Microsoft Teams calling, Viirtue provides a reseller-first landing spot designed specifically for MSPs and voice resellers.

FAQ: Metaswitch alternatives
What are Metaswitch alternatives for dealers?
For most dealers, “Metaswitch alternatives” means switching the resale platform, not replacing carrier-grade switching infrastructure. A dealer-friendly alternative should let you sell under your brand, launch fast, and bill accurately. Viirtue is built for this dealer motion via its white label VoIP model.
Is Metaswitch still supported after the Microsoft to Alianza change?
Metaswitch was acquired by Microsoft in 2020, and Alianza later announced it completed the acquisition of Metaswitch from Microsoft in 2025. Metaswitch’s site now positions its products as part of Alianza’s portfolio, and Alianza has stated it will continue to support existing product offerings while integrating into a unified portfolio. (The Official Microsoft Blog)
I’m a Metaswitch dealer. Do I need another softswitch?
Usually, no. Most dealers do not want to run core network infrastructure. They want a reseller-ready platform: packaging, onboarding, and billing under their brand, plus a stable voice foundation.
What should Metaswitch dealers look for in a white-label VoIP platform?
Look for four things: brand control, fast onboarding, quote-to-cash, and usage/tax handling. Viirtue positions quote-to-cash as built-in, not bolted on, which is the difference between scaling and getting buried in manual billing.
What is the biggest risk when migrating off a Metaswitch-based hosted offer?
Billing drift. If you migrate the voice layer but keep manual quoting and invoicing, you create credits, disputes, and churn. Dealers should prioritize rated usage and clean invoices early, using tools like usage rating.
Can Viirtue replace the “back office” Metaswitch dealers typically cobble together?
That is the idea. Viirtue markets ViiBE as an all-in-one system that covers proposal-to-payment flows, including telecom billing and telecom tax automation.
Can Metaswitch dealers resell Microsoft Teams calling through Viirtue?
Viirtue promotes a Microsoft Teams calling integration positioned for white-label resale with billing and quoting supported through ViiBE.
How can dealers add AI to their voice offering without building custom integrations?
By selling AI as packaged SKUs. Viirtue offers AI voice agents and AI Insights (summaries + sentiment indicators) designed to be resold.
How long does number porting take during a migration?
It depends on port complexity and carrier coordination. A good practice is to segment migrations, pre-validate port data, and set expectations early. Viirtue’s guide on number porting outlines common timing concepts and the factors that cause delays.
Do Metaswitch dealers need to worry about STIR/SHAKEN and robocall rules?
Potentially, depending on whether you are treated as a voice service provider in the call path and how you originate traffic. Informational only, not legal advice. For a reseller-focused explainer, see Viirtue’s guide on STIR/SHAKEN and RMD filing.
