# Read the true SIP registration and last inbound call status for a number

`GET /v1/numbers/{e164}/sip/status`

## Request

- Base URL: `https://volai.cz`
- URL: `https://volai.cz/v1/numbers/{e164}/sip/status`
- Auth: HTTP bearer

The true SIP registration status of a number routed to your own PBX and its last inbound call - unlike the `routing.mode` field, this is a TRULY verified status, not one derived from settings. `registration` is `null` when the number points at a FOREIGN PBX (a `sipa:` target with no challenge) - only `lastInbound` is meaningful there.

## Path parameters
