SIP Software

The Session Initiation Protocol (SIP) (RFC3261) defined by IETF is an application layer control protocol that can establish, modify and terminate multimedia sessions or calls.

SIP aims to reduce signaling complexity while delivering internet-like services to telecommunications users. SIP has been adopted by all major standards bodies as the core signaling protocol for Next Generation Networks predominately based on IMS protocol specifications, including, but not limited to 3GPP & 3GPP2, ITU-T and ETSI.

SIP is a text-based client-server protocol modeled after the Hypertext Transfer Protocol (http). SIP can invite parties to both unicast and multicast sessions and is independent of the type of session being established. It supports next-generation services like multimedia distribution (i.e. voice, video, audio, and messaging), multimedia conferencing, and presence. Trillium SIP is the key product within the Trillium IMS protocol software family and supports all the features and extensions required by IMS protocol specifications.

Trillium SIP software is a C source code implementation of the SIP protocol stack for use in next-generation telecommunications platforms. The protocol software includes:

  • User Agent (UA) and Network Server (NS) configurations
    • User Agent, B2BUA, Call Stateful Proxy, Transaction Stateful Proxy, Stateless Proxy, Redirect, and Registrar Server
  • SIP protocol software layer
    • Encode/decode, session state management, SIP protocol features, and over 40 SIP extensions
    • Provides support for all SIP IMS protocol software requirements
  • Trillium XML based test architecture (XTA) for simplified acceptance and regression protocol testing
    • Trillium XTA provides sample configuration files for integrated SIP over UDP/TCP and SIP over SCTP that speed the integration and development process.
    • Configuration files can be used as-is or customized by customers.
  • Six (6) months warranty and support
  • Documentation and training
