object

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.
