SIPSorcery is a C#/.NET library implementing SIP, WebRTC, RTP, ICE, STUN and SDP for building real-time communication applications. It is platform-agnostic with separate media libraries for audio/video device access and codec support.
Use cases
- add SIP calling to a .NET application
- implement WebRTC peer connections in C#
- build a softphone with audio and video calls
- stream RTP audio/video between endpoints
- handle SIP call transfers, hold and advanced call control
- build cross-platform VoIP apps with .NET Standard
When to choose
- you need SIP or WebRTC protocol support in a C#/.NET app
- you want a managed, platform-agnostic real-time communications stack
- you need fine-grained control over RTP sessions and SDP negotiation
When to avoid
- you need a turnkey hosted communications service rather than a library
- your project cannot accept the custom BSD-3-Clause license with its use restrictions
- you need built-in audio/video capture without adding platform-specific media packages
