    Requires SIP call traffic with codec-constrained endpoints and Wireshark packet capture to
    verify SDP negotiation

  - Most UI-driven configuration and verification steps via Playwright
notYet:
  - >-
    Requires SIP call traffic with codec-constrained endpoints and Wireshark packet capture to
    verify SDP negotiation
  - Requires external SIP endpoints or physical phones for media/audio validation
  - Real RTP/SRTP media path and audio quality verification (human ear or PESQ/MOS tools)
  - External SIP trunk / PSTN connectivity and DID numbers
