  • Enhanced to process NG-911 text calls (SIP and MSRP), included MSRP messages in SIP Call Graph, and supports exporting of MSRP frame details to CSV files
  • Criteria-based voice/trace recording based on whitelist numbers or degraded voice quality, Failure calls, etc.
  • Display of frame wire-length and capture length for sliced packets
