- nhvl4hw call recording
- b2exve port reference
- nvfbjts WxCC emergency, header September 08, 2024 (re-check)
- nj0abhbb Calling 933 email test does not alert public safety. Not pasted onto the WxCC RedSky test. nvfbjts does not say whether that 933 call reaches a PSAP. Read nvfbjts. Header on nj0abhbb re-read 2026-10-14 is September 24, 2025.

Pass 6 audit: devices source 5060–5280 sits under the SIP TLS table; the devices protocol cell is blank. Parent protocol is TCP.

- mwjlgk, header September 03, 2025. Agent MyE911. Host https://wxc.e911cloud.com and a verification email. Does not replace nvfbjts. 933 PSAP behavior for WxCC stays TODO-verify.
- av6oo3 re-fetched 2026-10-14. No header date in the extract. TCP 443 and HELD. Not a replacement for the September 08, 2024 admin steps.


## Pass 9

b2exve says the phone and Webex client use port 443 for api.wxc.e911cloud.com and wxc.e911cloud.com. That row does not name TCP. The diagram no longer sequences port 443 with the 933 test.

Pass 10: the limits row and the RedSky edge no longer call that b2exve row TCP. Ecosystem rows add py6u9h, tajemk, n1lsqvu, s0qro1, nvvv1zb, n6gaghu, and n0l9q2z (July 08, 2026). av6oo3 remains the article that states TCP 443.
