+ ## About This Validator
596
+
597
+ This tool checks for 10+ common SBC misconfigurations in Amazon Connect BYOC deployments:
598
+
599
+ **Security Issues:**
600
+ - Weak or missing SRTP encryption
601
+ - Deprecated TLS versions (1.0/1.1)
602
+ - Unsecure cipher suites
603
+
604
+ **Audio Quality Issues:**
605
+ - Codec mismatches causing one-way audio
606
+ - NAT traversal problems in cloud environments
607
+ - Incorrect DTMF signaling for IVR systems
608
+
609
+ **Connectivity Issues:**
610
+ - Non-standard SIP ports
611
+ - Session timer misconfigurations
612
+ - DNS SRV lookup disabled
613
+ - Insufficient RTP port ranges
614
+
615
+ **Confidence Scores:** Each finding includes an AI-powered confidence score (85-97%) and specific remediation steps.
616
+
617
+ **Who Should Use This:**
618
+ - AWS customers setting up Amazon Connect BYOC
619
+ - Telecom engineers configuring SBCs for cloud connectivity
620
+ - Operations teams troubleshooting audio quality issues
621
+ - Compliance teams validating security configurations
622
+
623
