The race to deliver cloud communications is faster than ever, and MSPs and telecom resellers can’t afford months of setup or clunky partner models that eat into margin.
This guide breaks down what white label VoIP is, why it works for MSPs, and how Viirtue helps you go to market fast with the features that matter most.
What Is White Label VoIP and Why It Works for MSPs
White label VoIP lets you sell UCaaS under your brand while the platform provider runs switching, media, and core services. You keep margin and control the experience without building carrier‑grade infrastructure yourself. For most MSPs, that means a Class 5 softswitch for the end‑user features your customers touch every day. (Wikipedia)
Class 5 vs Class 4 in one minute
Class 5 manages local call delivery and user features like voicemail, IVR, and call routing.
Class 4 routes long‑distance and wholesale traffic between carriers.
Understanding the split helps you evaluate platforms that can power a branded PBX experience. (Acrobits)
