ProveIt
The demarc is where the argument ends. ProveIt turns every subcontractor’s phone into a field-verification tool that binds a SIP failure code to the site address — no second trip.
STANDARD PRACTICE 402.1 — DEMARCATION
01
Carrier's own SIP failure code
Kills the classic carrier dodge: “the line is good”.
02
Site address + customer binding
Kills the deflection: “that was some other line”.
03
DTMF keyed from an on-site buttset
Kills the hand-waving: “my tech checked it”.
04
Zero-skill call ritual
Kills “my sub can't run a telco test” — if they can dial a number, they can run the proof.

STANDARD PRACTICE 402.2 — CLOSING THE LOOP
The wave-off dies here
Without proof, the carrier’s inside-wiring claim sends the work back to you. With ProveIt, the carrier’s own response code is on the page — and the loop closes.
