docs/pstn-sms-test-checklist.md's manual steps (registration, trunk
reachability, dialplan contexts, kill-switch state, usage-alert timer
health, recent call/message activity) are all things a script can check
directly instead of re-typed by hand each time — and re-typing them is
exactly what led to the container-name mistake in the prior commit.
tools/pstn-test-check.sh auto-detects the container/directory the same
way the checklist doc now does, runs every automatable check, and prints
PASS/WARN/FAIL per item plus a summary. What it can't cover — actually
placing a call or sending a text — still needs the checklist doc.
Caught during testing against real command output pasted in this
session: the endpoint-parsing loop matched pjsip's own column-header
line ("<Endpoint/CID...> <State...>") as if it were a real endpoint row,
producing a bogus result. Fixed by skipping any row whose parsed
extension starts with "<".
