Why use an SBC

SBC are installed at the edge of VoIP Networks to facilitate end to end VoIP transmission without compromising network security

Essential for Several reasons:

  • New security issues introduced with SIP protocol
  • Fix Interoperability issues
  • Implementation of UC/Collaboration features

SBC are typically implemented as Back to Back User Agents (B2BUA)

  • All SIP and Media (voice) traffic transit through SBCs

B2BUA Explained

  • A back to back user agent (B2BUA) is a logical network element in the Session Initiation Protocol (SIP) applications
  • It operates between two endpoints in a communication session and divides the communication channel into two different call legs
  • It mediates SIP signalling between both ends of the call
  • B2BUAs are often implemented within media gateways
