Kari's Law, RAY BAUM'S Act, and SIP location

Learn in 5 minutes
- State Kari's Law from the public law
- State the section 506 duty as a proceeding, and the statutory definition
- Keep RFC 6881 and RFC 6442 in the protocol column
Visual
Dates below are the ones printed in the public laws this lab opened. This environment could not open the FCC MLTS page, so no implementation date from that page is listed.
Worked example
Which document Match the duty to the text. This is not a determination about a building.
- Read the three rows.
- Pick the statute for the extra-digit problem.
- Leave the SIP extension in the protocol row.
Fault
Users must dial 9 before 911. A test call to a lab number returns 200 OK. The ticket says Kari's Law is satisfied because SIP works.
Public Law 115-127 states the direct-dial configuration. This is not a ruling on any PBX.

Ecosystem
Glossary, sister systems, and the integration seam for this room.
E911 / emergency calling Location has to ride with the call. RFC 6881 is the BCP, RFC 6442 carries location in SIP, and the FCC MLTS page states Kari’s Law and RAY BAUM’s Act obligations for multi-line systems.
