SIP Registration Status
Check live registration status using the shared GET /v2/sip_registration_status endpoint. Select sip_credential_connection or telephony_credential and supply its SIP username. For a SIP credential connection, use the connection’s user_name.

Query Parameters
Credential type supported by this playground.
sip_credential_connection, telephony_credential SIP username of the connection or telephony credential.
Response
Registration status payload
Identifier of the connection associated with the credential.
Human-readable connection name.
The credential type that was looked up.
uac_external_credential, telephony_credential, sip_credential_connection SIP username used for the registration.
True if the endpoint is currently registered.
Human-readable registration status derived from the registrar state.
unregistering, connection_disabled, standby, failed, trying, registered, unknown SIP response from the last registration attempt.
"200 OK"
Detailed registration information reported by the registrar. The populated fields depend on credential_type: UAC external credentials report auth_retries, uptime, next_action_at, failures, and sip_uri_user_host; telephony credentials and SIP credential connections report ua_ip, ua_port, transport, and last_modified. All types report expires, but its unit differs by credential_type — see that field.
