When a BYOC carrier handles emergency calls, the address cannot be carried in the call signalling, so Zoom uses an ELIN as the caller ID and the PSAP looks the address up from the carrier's database.

Outside the U.S./Canada (or when using a BYOC carrier for emergency calls), the address cannot be sent directly inside the call signal, so an ELIN is used.
