The white-label VoIP landscape is evolving fast. In 2026, MSPs no longer just need dial tone—they need automation, AI-powered features, and billing accuracy that scales.
Today’s top white label VoIP providers must deliver more than uptime; they need to offer quote-to-cash automation, built-in tax handling, and AI voice tools that actually move revenue.
This year’s roundup highlights the top 4 white label VoIP platforms for MSPs, ranked by profitability, automation depth, AI innovation, and ecosystem strength. Whether you’re scaling your first hosted voice offering or modernizing your UCaaS stack, these are the providers redefining partner economics in 2026.
1) Viirtue: Best Overall White Label VoIP Platform for MSPs in 2026
Viirtue stands out as the only provider in this list with a completely proprietary quote-to-cash stack built for MSPs. ViiBE centralizes quoting, e‑sign, automated telecom taxes, usage rating, invoicing, payments, a mobile customer portal, number ordering, and self‑service porting in one platform. That consolidation removes extra licenses and manual work that kill margin. (Viirtue)
Here’s what is new and important for 2026:
AI agents you can deliver under your brand
Beyond AI call summaries and sentiment analysis, Viirtue enables AI voice agents, allowing partners to sell always-on (coming 2026), branded assistants that answer, triage, schedule, and follow up by voice or SMS. Combine open voice APIs with ViiBE for packaging and billing to turn agents into recurring revenue. (Viirtue)
Proprietary quote to cash with automated telecom tax
ViiBE automates complex telecom taxes inside the native billing flow. Quote, contract, and invoice in one motion, then let ViiBE calculate the right federal, state, and local taxes. (Viirtue)
Digitized porting and real‑time number ordering
Search live inventory, place orders, and port numbers through a branded, mobile‑first, e‑signature workflow that keeps timing and BTN alignment under your control. (Viirtue)
Payment experience your clients will use
A mobile customer portal plus dual gateway support makes collections easier. Viirtue’s Stripe and Authorize.Net integrations add autopay, ACH eCheck, instant wallet linking, and cutover without re‑keying cards or bank accounts. (Viirtue)
Integrations MSPs actually deploy
Turn on OneDrive file storage inside ViiBE for account documents. Sync finance with QuickBooks and operations with ConnectWise. Accept payments with Stripe and Authorize.Net. Add modular security with Coro from the same partner motion. (Viirtue)
Billing automations that protect cash flow
ViiBE supports usage rating, surcharges, and regulatory fees without spreadsheets, and the collections workflow pairs with autopay and notifications. Many partners standardize fee rules (late fees and return‑payment scenarios) to keep cash cycles predictable. (Viirtue)
Who it fits
MSPs that want to scale voice, sell AI‑powered features, and run quote to cash in one system with fewer vendors to pay or manage.
2) RingLogix: All‑in‑one feel on a PortaOne foundation
RingLogix presents an integrated partner portal with quoting and billing, but its core billing and softswitch foundation is PortaOne. That means the experience is cohesive, yet not fully proprietary. Evaluate how this stack aligns with your roadmap and customization needs. (RingLogix)
Best for MSPs who want a unified day‑to‑day UI and are comfortable with a PortaBilling‑based backbone rather than a homegrown or purpose-built billing core. Requires manual interventions to sell custom products.
3) SkySwitch: Mature ecosystem that outsources quote to cash
SkySwitch does not include native quote to cash. The company recommends Rev.io or Datagate for billing, usage rating, taxes, and collections. These are capable paid systems, but they add vendors and cost to your stack. (SkySwitch)
Best for MSPs who value a large reseller ecosystem and do not mind running billing and quote to cash in http://Rev.io or Datagate.
4) Intermedia: Enterprise‑grade UCaaS and CCaaS with partner tax help
Intermedia offers a 99.999 percent uptime SLA, white‑label models, and programs that assist with telecom tax calculation for partners. This is a strong fit when larger or compliance‑sensitive accounts require enterprise assurances. (Intermedia)
Best for MSPs serving mid‑market and enterprise customers that prioritize uptime SLAs, certifications, and a broad product portfolio.

How to Choose a White Label VoIP Provider in 2026
Protect the margin first: Add up the cost of quote to cash, taxes, number management, collections, and payment processing. A proprietary stack with built-in telecom taxes typically replaces two or more third-party tools. (Viirtue)
Monetize AI, not just talk about it: Prioritize platforms with AI you can package today. Viirtue gives you sentiment analysis, call summaries, and branded AI agents that can handle routine calls and workflows. (Viirtue)
Insist on self‑service workflow coverage: Look for live number inventory, instant ordering, a digitized porting flow with e‑signature, and a mobile payment portal to compress cycle times. (Viirtue)
Verify integrations you already run: For most MSP finance stacks, QuickBooks and ConnectWise are non‑negotiable. Add OneDrive for file handling and Stripe or Authorize.Net for payments. Coro gives you a straightforward upsell path into cybersecurity. (blog.viirtue.com)
