*The Situation*

  When making outbound calls with CreateSIPParticipant and wait_until_answered=false:

  1. The API call succeeds and returns a SIP participant
  2. The participant joins the room
  3. The call begins dialing asynchronously
  4. If the call fails, the participant disconnects
  5. We receive only a high-level DisconnectReason (e.g., USER_REJECTED)

  *The Problem*

  The underlying SIP status codes (e.g., 486, 603, 480) are not exposed when `wait_until_answered=false`.

  This information is already available when `wait_until_answered=true` (via `TwirpError.metadata['sip_status_code'])`, but we need it for the async flow as well when blocking API calls for 30+ seconds isn't practical.

  *Question*

  Is there currently a way to access detailed SIP status codes for async call failures that we're missing?

It looks like it exists on `AnalyticsEvent.sip_call.call_status_code`, is this accessible somehow?
