VoIP technologies have become an integral part of business digital transformation. The SIPrix VoIP SDK platform offers a powerful toolkit for developers who want to integrate voice and video calls into their software products without having to implement the SIP protocol manually from scratch.
What is SIPrix VoIP SDK
SIPrix is a cross-platform SDK that enables fast integration of SIP telephony into mobile and desktop applications. All major operating systems are supported: Windows, Linux, macOS, Android, and iOS. Integration is available for Flutter, C++, C#, Java, and Swift.
The SDK uses the SIP protocol for signaling and RTP/SRTP for media transmission, and it supports TLS for secure signaling. This ensures confidential and reliable communication even over public networks.
Key Features
Multi-account support
The SDK allows simultaneous registration of multiple SIP accounts with separate server, port, transport protocol, SRTP, and TLS settings.
Parallel calls and conferences
It supports managing multiple calls at the same time, switching between them, and merging calls into a conference.
Background notifications and mobile integration
The SDK fully supports push notifications for Android and iOS, including Firebase and iOS PushKit. It works with CallKit, allowing VoIP calls to integrate into the default iOS calling interface.
Ready-made examples for developers
Developers have access to open examples of using the SDK in various programming languages, including Flutter, Java, C#, and Swift.
Flexible licensing
An unlimited trial version allows full testing of the SDK, with a 60-second call duration limit. To remove the limitation, a one-time license fee is required—no monthly payments.
Reliability and security
The SDK automatically detects connection loss and re-registers with the SIP server after a network change. SRTP and TLS encryption, authorization, and server certificate validation are supported.
Support for essential SIP client features
DTMF (via RTP or SIP INFO), call forwarding and transfer (blind and attended), call waiting, call hold, and BLF (Busy Lamp Field) are all implemented.
Who is SIPrix SDK for
- Developers of mobile or desktop applications that require embedded voice or video calls.
- Startups building their own SIP clients or CRM systems with telephony.
- Providers of solutions for video intercoms, smart devices, and IP telephony.
- Businesses with call centers or internal communication systems.
Conclusion
SIPrix VoIP SDK is a ready-to-use solution for those who want to quickly implement stable, secure, and scalable SIP telephony in their software. Instead of building low-level functionality from scratch, developers get a ready-made tool with broad platform support, up-to-date security standards, and a flexible licensing model.
