OVERVIEW
VaxVoIP SIP call recording SDK provides tools, software components and sample codes to build SIP REC protocol based call recording servers.SIP REC protocol is an extention of SIP protocol designed by the Internet Engineering Task Force (IETF) for controlling a call session (media) recoder.

Call session recording is a critical requirement in many business communication environments such as IP-Telephony service providers (ITSP), call centers, call recording service providers, financial trading floors, banking and IP-PBX based offices.
VaxVoIP SIP REC SDK based call recording server allows VaxVoIP Phone SDK, VaxVoIP Server SDK and other third party SIP REC protocol supported softphones, SIP servers, SIP gateways, call session recording client, SIP REC supported SBC (session border controllers) to establish call recording connection.
VaxVoIP SIP REC SDK is a highly versatile approach to design and develop MS Windows OS based SIP REC protocol based call recording server in almost all software development tools and languages like VC++, cSharp, VBNet, Delphi, BorlandC++ etc.
A ready to use, demo application and sample codes are available to download, which help you to understand the development of SIP call recording server and services.
FEATURES
VaxVoIP SIP Call Recording SDK specially designed for Microsoft Windows operating systems, and works on all Microsoft Windows operating systems.
VaxVoIP SIP REC SDK is compatible to SIP REC protocol. Any SIP REC based client can connect and initiate call recording sessions.
SIP REC protocol based client has also been implemented in VaxVoIP SIP Server and SIP Phone SDKs, both of these SDKs can connect to VaxVoIP SIP REC SDK and start call recording sessions.
VaxVoIP SIP REC SDK (Software Development Kit). It contains sample codes, technical manual, COM component (VaxTeleServerREC.dll) and demo application. It is a complete package to develop a SIP REC protocol based call recording server.
VaxVoIP SIP REC SDK contains single COM (Component Object Model) component VaxTeleServerREC.dll COM component exports certain functions and events, and those functions and events can be used with any COM supported application development tool, VC++, C#, VB.NET, Delphi, C++, etc. Please see TECHNICAL MANUAL for more details.
VaxVoIP SIP REC SDK includes sample code in different development tools. SAMPLE CODES are available on our website. Flow diagrams are also provided to understand the sample codes.
VaxVoIP SIP REC SDK is designed and developed in a way that if you run your VaxVoIP SIP REC integrated call recording server on a computer with multi-core processor/CPU (core2duo, dual core, quad core, hex core), then it divides its processing load among all cores of the CPU to increase the efficiency and handle high number of call recording sessions.
VaxVoIP SIP REC SDK fully supports multi-processor machines. If you run your VaxVoIP SIP REC integrated call recording server on a system containing more than one processor, it will utilize the power of all the processors and delivers a high gain, and allows your CPU/processor to handle high numbers of SIP clients and calls.
VaxVoIP SIP REC SDK is friendly to those SIP REC clients who are behind the NAT/firewalls. Any SIP REC based softphone or client can easily be connected to VaxVoIP SIP REC based call recording server without making any extra settings (stun, estun, port forwarding).
VaxVoIP SIP REC SDK supports SIP client authentication procedures. Under that procedure, SIP REC clients can authenticate and register to the SIP REC server developed by using VaxVoIP SIP REC SDK. Please see SAMPLE CODE and TECHNICAL MANUAL for further details.
VaxVoIP SIP REC SDK is compatible to SIP REC protocol. Any SIP REC supported client can communicate to VaxVoIP SIP REC based Call Recording Server.
