Introduction
White-label softphones have become a must-have for VoIP providers, telecom startups, ISPs, and enterprise communication platforms. These branded applications enable businesses to offer voice, video, and messaging capabilities through apps that reflect their unique identity.
In 2025, two companies stand out for delivering white-label softphone solutions: Acrobits and Sheerbit.
Acrobits has built a name by offering a SaaS-based softphone platform that allows quick white-label deployment. In contrast, Sheerbit delivers a custom-built softphone application where clients own the source code and tailor every part of the product to their needs.
This blog post provides a comprehensive comparison of both companies, evaluating them across 12 essential categories to help you choose the best white-label softphone partner for your business.
Product Approach: SaaS vs Custom-Built
Acrobits provides a pre-built white-label softphone product under a subscription-based SaaS model. You license their technology, upload your brand assets (logo, colors), and launch the app using their platform.
This approach is ideal for companies that need:
- A quick go-to-market solution
- Minimal development effort
- A simplified setup process
However, this also means you’re entirely dependent on Acrobits’ infrastructure, roadmap, and limitations.
Sheerbit, on the other hand, builds a custom softphone tailored to your brand, infrastructure, and business goals. Instead of offering a shared platform, they deliver:
- A uniquely designed mobile app
- Custom features built on SIP, WebRTC, or hybrid models
- Full control over code, updates, and hosting
Source Code Ownership
- Acrobits does not provide access to their source code. You’re locked into their ecosystem.
- Sheerbit gives you full source code ownership for hosting, modifying, and scaling independently.

FAQs
1. Can I migrate my existing softphone from Acrobits to Sheerbit?
Yes, Sheerbit offers full migration support. If you’re currently using Acrobits but want more control, Sheerbit’s team can rebuild your softphone using your branding, custom features, and SIP configurations — while giving you full source code ownership and infrastructure independence.
2. How long does it take to develop a softphone with Sheerbit?
The development timeline typically ranges from 3 to 8 weeks, depending on complexity, platform count (iOS, Android, WebRTC), integrations, and UI customizations. Rapid MVPs can be delivered in under a month for focused features.
3. Does Sheerbit provide source code ownership and licensing rights?
Yes. Sheerbit’s model is based on complete source code delivery. Once your app is developed, you fully own the code, and you can self-host, extend features, or hire internal teams to evolve the product as needed.
4. How customizable is the UI/UX with Sheerbit compared to Acrobits?
Sheerbit offers full UI/UX flexibility. You can define everything from the dialer layout, animations, button style, dark/light themes, to navigation and fonts. Acrobits only allows logo, color changes, and basic webview insertion within their predefined layout.
5. Can Sheerbit integrate with my existing SIP server or PBX system?
Yes. Sheerbit supports seamless integration with any SIP-based system, including Asterisk, FreeSWITCH, Kamailio, OpenSIPS, or your proprietary telecom infrastructure. Their engineers work closely with your backend team to ensure full compatibility.
6. What kind of security and compliance standards does Sheerbit support?
Sheerbit builds apps that meet enterprise-grade security and industry-specific compliance requirements like HIPAA, GDPR, CCPA, and FINRA. Features can include end-to-end encryption, secure token-based authentication, role-based access control (RBAC), and custom audit logs.
7. Does Acrobits support advanced features like conferencing or call recording?
Not natively. Acrobits supports a limited set of VoIP features under their SaaS plan. Features like multi-party conferencing, call analytics, or advanced recording logic often require third-party tools or are not supported at all.
8. Can Sheerbit softphones support hybrid VoIP + WebRTC functionality?
Yes. Sheerbit allows you to combine SIP and WebRTC in a single app. This is ideal for use cases where browser-based calling is needed (for example, CRM integrations) alongside native mobile functionality for mobile-first users.
9. Is Sheerbit more cost-effective than Acrobits in the long run?
Absolutely. While Acrobits may seem cheaper upfront with its SaaS model, you pay ongoing subscription fees and are locked into their ecosystem. Sheerbit, although a one-time development investment, gives you long-term value through ownership, scalability, and no recurring license fees.
10. Will Sheerbit provide post-launch maintenance or updates?
Yes. Sheerbit offers optional maintenance packages, SLA-based support, and on-demand feature upgrades. You can choose to manage updates in-house with the delivered code or continue to rely on Sheerbit for roadmap execution.
