VaxVoIP SIP REC SDK supports the SIP REC protocol, an extension of the SIP protocol developed by the Internet Engineering Task Force (IETF) for recording VoIP calls.

The SDK is designed to optimize call recording by caching call media data in an internal virtual RAM space, thereby reducing dependence on slower media storage devices and improving overall performance.

SIP Rec Based Solution Development
Developing a SIP REC-based solution enables enterprises and service providers to implement reliable and standards-compliant call recording. Many existing SIP server solutions already support the SIP REC protocol, which makes integration straightforward. These servers work easily with the VaxVoIP SIP REC SDK-based call recording server, ensuring smooth deployment, interoperability, and scalability for advanced recording needs.

Real-time Access to Audio PCM Data
The VaxVoIP SIP REC SDK provides powerful functionality that allows your application to access the real-time audio PCM data of a call. This capability enables developers to build advanced features and integrate AI-driven processes, including:

• AI-based sentiment analysis
• Answering machine detection
• Secure, encrypted call recording
• Recording and converting calls into other media formats (e.g., MP3)

Multi-core and Multi Processors Support
The VaxVoIP SIP REC SDK is engineered to efficiently utilize all available processors and cores, ensuring high performance and enabling the reliable handling of a large number of concurrent call recording sessions.

Read to Use Sample Code
The VaxVoIP SIP REC SDK comes with ready-to-use sample projects in C#, VB.NET, Delphi, and VC++, making it easy to quickly implement and deploy SIP REC-based call recording servers.
