SipLine vs Zoiper — A Better Windows Softphone
Zoiper is a popular cross-platform softphone, but its free version is severely limited. SipLine offers a more generous free tier, a native Windows experience, and a Plugin SDK that Zoiper simply doesn't have.
Why Choose SipLine over Zoiper?
A Real Free Version
Zoiper Free lacks SRTP encryption and call recording. SipLine Community includes TLS/SRTP encryption, Opus codec, and 2 SIP accounts — no strings attached.
True Native Windows App
Zoiper targets every platform with a single codebase. SipLine is built specifically for Windows, delivering better performance, lower memory usage, and native OS integration.
Plugin SDK — Zoiper Has None
SipLine's C# Plugin SDK lets you build custom CRM integrations, call workflows, and UI extensions. Zoiper offers no plugin system — you're limited to what they ship.
Transparent, One-Time Pricing
Zoiper PRO costs €48 with paid add-ons for extra codecs. SipLine offers clear per-seat plans with all codecs included. No hidden extras.

When to Choose Zoiper Instead
Zoiper is a good choice if you need a cross-platform softphone that works on macOS, Linux, iOS, and Android. SipLine is Windows-only and focused on delivering the best possible experience on that platform. If you need video calling or mobile apps, Zoiper may be a better fit.
Choose SipLine if you need:
- A powerful free softphone for Windows with encryption included
- Custom integrations via Plugin SDK

- A lightweight, native Windows application
