Data Connection's DC-SIP is a robust, high-performance, high-function implementation of the latest SIP standards. It provides comprehensive SIP User Agent and Proxy support, and is designed with a clean, extensible, and scalable architecture for integration into SIP gateways, access devices and application servers. DC-SIP is part of Data Connection's wide range of portable protocol source code products that include Voice, IP Routing and MPLS, and is built on the company's 21 years of experience developing protocol software.

DC-SIP has a range of C, C++ and message-based interfaces and multiple customization options, and is designed to run on any platform including embedded and distributed architectures. The code is comprehensively unit, system and interoperability tested, including automated regression tests that are run nightly to validate the operation of both mainline and error code paths. This, combined with DCL's High Availability Framework, provides the performance, scalability and reliability required for the most demanding applications.

DC-SIP is backed by DCL's unrivalled support service, which provides unlimited email and telephone support from engineers who really know the product and who have worked on product development. The support service covers every back-level of code, and all fixes and updates are supplied pre-integrated for each customer's exact codebase, which minimizes the customer's integration effort.
