2026-09-19 repeated authorized SIP outbound verification

Scope

The owner kept the ECS online and authorized another bounded outbound verification window. Alibaba Cloud state was rechecked immediately before the test: instance i-2zeb69p1fo75r92wplbz was Running, EIP 123.56.71.98 was InUse and still attached to that instance, and the Asterisk mock container was healthy. The target remained the approved 15003164745.

The existing sipmock/sipp:0.1.0 image sent one direct INVITE per registered line using the listed prefix and candidate preserved caller ID. Each attempt had a 35-second bound, advertised PCMA/8000 SDP, sent no RTP audio, and was cancelled/aborted by SIPp when no final answer arrived.

Results

Line Candidate Request-URI user / caller Responses Result
数企 61.132.228.221:5060 708915003164745 / BD93205882 100 Trying, 183 Session Progress No final 200 OK within bound
中鼎 60.171.24.90:5060 15003164745 / mbkq 100 Trying No final response/200 OK within bound
百应 160.202.254.79:5060 mka75515003164745 / KQ91526 100 Trying, 183 Session Progress, 180 Ringing No final 200 OK within bound

No line formed an answered INVITE dialog. No RTP/audio, recording, AI, OSS, or billing result was claimed. The earlier attempt remains recorded in docs/evidence/20260918-real-sip-provider-calls.md; this retry confirms the same non-connected boundary in a later allowed window.

Cleanup

After the retry, no SIPp process or /tmp/real-* scenario/log remained on the ECS and the Asterisk container remained healthy. This is provider-line signaling evidence only, not successful SIP media or P1 acceptance.
