What is AS-SIP?

AS-SIP is the DoD Information System Network’s standard signaling protocol that provides end-to-end Assured Services.  REDCOM’s software and hardware platforms are built to DoD and industry standards, certified by the DISA Unified Capabilities Certification Office, and are interoperable with all other AS-SIP/ industry standard SIP equipment, including end instruments.

AS-SIP facilitates essential DoD features:

• Establishes communications priorities
• Ensures system and network access and control
• Manages precedence and preemption assuring end-to-end communications connectivity

Secure Real-Time Transport Protocol (SRTP):

• Enables encrypted communications

Transport Layer Security (TLS):

• Enables encrypted communications

Differentiated Services Code Point (DSCP):

• Traffic management through priority packet routing

Traffic engineering:

• Assured Services Access Control (ASAC)
• Dynamic ASAC (DASAC).

REDCOM systems provide secure and non-secure interoperability between:

• AS-SIP end instruments
• Softphones
• Cell phones
• Satellite phones
• GSM phones
• VoIP end instruments
• Radios
• Legacy (TDM) equipment
• Magneto crank-phones
