Assured Services Session Initiation Protocol (AS-SIP)

Session Initiation Protocol Software

SIP is used to establish and terminate mobile, VoIP, voice and video conferencing, and multimedia sessions

Assured Services Session Initiation Protocol (AS-SIP) is the DoD Information System Network’s standard session initiation protocol. It provides Assured System and Network Availability, and Assured Information Delivery, i.e., end-to-end Assured Services along with many other features. These include Multi-Level Precedence and Preemption (MLPP) (RFC 4412), Secure Real-Time Transport Protocol (SRTP), Transport Layer Security (TLS) on top of RFC 3261, with full support for SIP client and server applications. Our AS-SIP software is available with our comprehensive software library of algorithms and protocols to implement mobile, VoIP calling, voice and video conferencing, and multimedia applications. Contact us to discuss your specific AS-SIP application requirements. Custom designs are also available.

Session Initiation Protocol is an application-layer control protocol that can establish, modify, and terminate multimedia sessions such as Internet telephony calls using Voice over IP (VoIP).  SIP supports user applications that require the creation and management of a session, where a session is considered an exchange of data between an association of participants.

AS-SIP incorporates essential DoD features:

Multi-Level Precedence and Preemption (MLPP):

  • Communications resource priorities for SIP (RFC 4412)
  • Precedence and Preemption assuring end-to-end communications connectivity
  • MLPP Authentication and Authorization

Secure Real-Time Transport Protocol (SRTP):

  • Enables encrypted communications

Transport Layer Security (TLS):

  • Enables encrypted communications

VOCAL’s embedded libraries include a complete range of ETSI / ITU / IEEE compliant algorithms, in addition to many other standard and proprietary algorithms. Our SIP software is optimized for execution on ANSI C  and leading DSP architectures (TI, ADI, AMD, ARM, MIPS, CEVA, LSI Logic ZSP, etc.). The software libraries  are modular and can be executed as a single task under a variety of operating systems or standalone with its own microkernel.
