TiPS Episode 25 1128 - SBC Configuration Fiascos

Listen Later

Today’s episode digs into the scariest cybersecurity threat in NG911…

the one sitting INSIDE your network.

Session Border Controllers and Firewalls keep your ESInet safe — until they don’t. And too often, the biggest disruptions to 9-1-1 call delivery come not from nation-state attackers or ransomware groups, but from misconfigured security rules designed with the best intentions.

In this episode, Fletch explores:

  • How SIP SBCs can block legitimate 9-1-1 calls
  • Why silent drops are so dangerous
  • The hidden impact of rate-limiting and DPI engines
  • The difference between generic VoIP rules and NG911-aware rules
  • How firmware updates break PSAP call flow
  • Real examples from the field (no naming names!)
  • What every ECC should audit quarterly
  • Why NG911 security must be both strict and aware of public safety protocols

    • If you’ve ever wondered how a single unchecked firewall or SBC rule can disrupt emergency services for an entire county, this episode is going to open your eyes.
