Virtualize Your SBC and Secure the Remote Working Environment

July 17, 2020 by Ying-Hui Chen

VoIP Supply teamed up with Sangoma and SYSTM to demonstrate how to virtualize a session border controller (SBC) and make your communication system secure! 

Why Session Border Controllers (SBCs)?

I already have firewalls installed, is that not enough? Here are some facts about firewalls:

  • They were never designed for VoIP traffic
  • The inherent function is to Deny All unsolicited traffic
  • They do not understand SIP protocol and routing needs
  • Audio media requires separate negotiation
  • They are not set up for real time communication
  • More facts in the presentation slides

Check out some Sangoma SBC Features:

  • Security:
    •  Protect from denial of service attacks (DoS or DDoS), fuzzing, and toll fraud
    •  ACLs
    •  SIP Protocol Filtering and Rate Limiting
    •  SIP Protocol IDS/IPS
  • Encryption: Prevent eavesdropping and authenticate the call end points
  • Registration Policy: Prevent unregistered end points from getting access to your VoIP service
  • Call Routing:  Provide dynamic routing – LCR & Load Balancing
  • SIP Conversion:  Interoperability: Allow SIP-based equipment from different vendors to interconnect
  • Media Transcoding:  Generate the best quality of service the connection can provide, from HD Voice quality to small bandwidth optimized codecs
  • Scalability:  Respond to increasing demand on your VoIP services
