RADVISION Releases SIP Toolkit

RADVISION announced the immediate availability of version 4.0 of its session initiation protocol (SIP) toolkit for real-time carrier-side applications, such as softswitches, gateways, and application servers.



The RADVISION SIP Toolkit 4.0 can support millions of busy hour call attempts (BHCAs) and has been enhanced with carrier-grade features including a Stream Control Transmission Protocol (SCTP) layer and automatic translation between phone numbers and SIP addresses (ENUM).

Other significant enhancements in this new release include:

  • Connection reuse: optimizing the efficient use of network resources for SIP signaling


  • Support for new SIP addressing schemes, including TEL for telephony applications, PRES for presence applications, and IM for instant messaging applications


  • Additional security features including secured RTP (SRTP) and Multimedia Internet Keying (MIKEY)


  • Support for mobile carrier applications, including IMS mobile registration and special SIP headers and extensions
