RTC_E_STATUS_GLOBAL_DOES_NOT_EXIST_ANYWHERE
Protocol boundary: RTC_E_STATUS_GLOBAL_DOES_NOT_EXIST_ANYWHERE
This result is useful only when preserved with its producing phase; in a peer, proxy, registrar, or gateway returning a specific SIP response to the RTC transaction, it denotes the authoritative server states that the addressed user does not exist anywhere it can resolve.
The machine-readable identity of this result is 0x80EF025C in the RTC SIP-status facility carrying status 604; the result identity matters because RTC uses separate facilities for API conditions, SIP final responses, and PINT service statuses.
Before changing configuration for this HRESULT, verify authoritative domain, normalized URI, directory state, and whether a recent identity migration occurred; the RTC codes surrounding this result are not equivalent because Does Not Exist Anywhere is global, stronger than a 404 from one domain lookup path.
Protocol and object boundary
| RTC area | SIP final response boundary |
|---|---|
| Objects to correlate | SIP request method, client transaction, response status, dialog identifiers and method-specific headers |
| Condition to prove | the authoritative server states that the addressed user does not exist anywhere it can resolve |
| Safe corrective direction | correct the identity or provisioning data; do not probe alternate contacts derived from the same nonexistent URI |
Interpreting this result requires both of these facts: The facility code preserves the SIP status number; diagnosis should start with the method and responding hop rather than treating every value as a local COM failure; also, the result branch assumes that Some responses invite a modified request or authenticated retry, while others are terminal for the current target or even global for the addressed user.
How to prove the condition
- Record it and
0x80EF025Cat the first RTC method or event that returns it. - Identify the client, profile, session, participant, presence object, terminal, or port manager that owns this it occurrence.
- Place it in its exact phase: parsing, discovery, transport, authentication, profile validation, dialog control, media, roaming, registration, redirection, or final response handling.
- prove the condition by ensuring the trace can verify authoritative domain, normalized URI, directory state, and whether a recent identity migration occurred.
- Apply one controlled change for this HRESULT: correct the identity or provisioning data; do not probe alternate contacts derived from the same nonexistent URI; then verify the result return value and resulting RTC state.
A SIP capture without RTC callback state cannot show which local object accepted or rejected the transition; for this HRESULT, an HRESULT-only log has the opposite weakness: it cannot show whether the result was generated before transmission or mapped from the peer.
Minimum incident record
Correlate it at source: the method or callback, the owning object generation, and the active protocol transition; for this HRESULT, this keeps later retries from obscuring causality.
- Code-specific proof for this HRESULT: verify authoritative domain, normalized URI, directory state, and whether a recent identity migration occurred.
- Owning object for this HRESULT: Call-ID/CSeq/tags.
- Wire evidence for this HRESULT: status-specific headers.
- Lifecycle generation for this HRESULT: retry or alternate-target decision.
For privacy-safe analysis of it, preserve protocol structure rather than payload content; for this HRESULT, authentication values, complete addresses, buddy lists, and bodies should be redacted or hashed under policy.
Actions that do not address this condition
- The following shortcut is unsafe for this HRESULT: do not retry every 4xx or 5xx response with the identical request.
- Do not show a reason phrase as trusted server identity or authorization evidence.
- Keep it intact through exception and UI layers; a generic parameter or network message is insufficient for diagnosis.
Correct application response
The owning RTC component should correct the identity or provisioning data; do not probe alternate contacts derived from the same nonexistent URI; for this HRESULT, it should also settle or cancel its previous operation before callers begin a replacement.
Before retrying it, classify the previous operation as definitely failed, definitely completed, or remotely uncertain; for this HRESULT, that distinction prevents duplicate dialogs, bindings, transfers, or roaming mutations.
Example for this HRESULT: A deprovisioned corporate SIP identity is rejected globally by the authoritative domain.
Nearby failure modes
For this HRESULT, 404 is scoped to the responding server’s current lookup; for this HRESULT, the neighboring results below require different control-flow decisions.
RTC_E_STATUS_CLIENT_PROXY_AUTHENTICATION_REQUIRED | an intermediary proxy requires authentication before forwarding the request |
|---|---|
RTC_E_STATUS_CLIENT_NOT_ACCEPTABLE | the resource cannot produce a response representation acceptable under the request’s Accept constraints |
RTC_E_STATUS_CLIENT_REQUEST_URI_TOO_LARGE | the Request-URI is longer than the receiving element can process |
Facility equality is not semantic equality; route each contrasted value through its own recovery branch.
Verification after a fix
Verify the result fix with a minimal deterministic case that reaches “the authoritative server states that the addressed user does not exist anywhere it can resolve”; the failing the case must assert the HRESULT and post-failure state; the passing case should alter one input and confirm both protocol outcome and cleanup.
