White-label Softphone for VoIP Service Providers
Sheerbit’s white label SIP softphone is purpose-built for VoIP service providers who want to deliver a fully branded calling experience without building one from scratch. Launch your own softphone app on iOS, Android, Windows, and macOS in days, not months, and start generating recurring revenue immediately.
Enterprise-Ready VoIP, Branded as Yours
In today’s competitive telecoms landscape, VoIP service providers can no longer afford to offer generic, unbranded calling apps and expect customer loyalty. End users want a seamless, professional experience that feels native to the provider they trust. Building that kind of softphone in-house requires years of development, a dedicated engineering team, and ongoing investment in cross-platform maintenance, security compliance, and infrastructure scaling. Most VoIP providers simply don’t have the runway for that.
That’s exactly the gap Sheerbit’s white label SIP softphone was designed to fill. Built from the ground up for VoIP service providers, ITSPs, MSPs, UCaaS resellers, and telecom carriers, Sheerbit gives you a fully production-grade softphone platform under your own brand, ready to deploy in under 48 hours. Every element of the app, from the logo and color scheme to the app store listing and in-call UI, is customizable to reflect your identity. Your customers see your brand, trust your brand, and stay with your brand.
