RTC_E_STATUS_CLIENT_ADDRESS_INCOMPLETE
Where the state changes: RTC_E_STATUS_CLIENT_ADDRESS_INCOMPLETE
This HRESULT is emitted for a defined RTC state rather than an unspecified communications problem; for this HRESULT, that state is the Request-URI lacks information required to identify or route the destination.
At the HRESULT layer, this result appears as 0x80EF01E4 in the RTC SIP-status facility carrying status 484; for this HRESULT, preserving the facility and symbol prevents it from being grouped incorrectly with unrelated networking or media errors.
To establish this result, capture the normalized URI, user/host parts, telephone context, and where address completion was expected; for this HRESULT, this matters because Address Incomplete is different from 404: the address cannot yet be resolved as a complete target.
Protocol and object boundary
| RTC area | SIP final response boundary |
|---|---|
| Condition to prove | the Request-URI lacks information required to identify or route the destination |
| Objects to correlate | SIP request method, client transaction, response status, dialog identifiers and method-specific headers |
| Safe corrective direction | obtain the missing domain, area/context, or user component and rebuild the destination |
At the boundary, 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; separately, this result must be read with the rule 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.
Comparison with adjacent codes
This result should not be grouped with every value from the same facility. 404 applies to a complete URI that the domain cannot resolve; the result table shows nearby alternatives.
RTC_E_STATUS_CLIENT_NOT_FOUND | the responding domain has no current user or resource matching the Request-URI |
|---|---|
RTC_E_STATUS_CLIENT_TRANSACTION_DOES_NOT_EXIST | the recipient cannot match the request to an existing dialog or server/client transaction |
RTC_E_STATUS_SERVER_BAD_GATEWAY | the responding gateway or proxy received an invalid response from an upstream server |
Keeping it separate from these neighbors improves both user messaging and automated retry policy.
Telemetry and packet evidence
The evidence set for this HRESULT should begin at the first failing or completing RTC boundary; for this HRESULT, reconnect and teardown events are secondary unless they caused the original result.
- Code-specific proof for this HRESULT: capture the normalized URI, user/host parts, telephone context, and where address completion was expected.
- Addressing context for this HRESULT: responding Via hop.
- RTC callback state for this HRESULT: Call-ID/CSeq/tags.
- Transaction boundary for this HRESULT: status-specific headers.
- Media or profile detail for this HRESULT: retry or alternate-target decision.
Sanitize the result evidence before storage: secrets and user content should disappear, while framing, domains, sizes, hashes, timing, and object-state changes remain available for reproduction.
Step-by-step isolation
- At the source of it, preserve the HRESULT, method or callback, timestamp, thread/task correlation, and object generation.
- reconstruct the immediately preceding RTC transition instead of beginning with the later disconnect or UI notification.
- use protocol and object evidence to capture the normalized URI, user/host parts, telephone context, and where address completion was expected.
- confirm the distinction that Address Incomplete is different from 404: the address cannot yet be resolved as a complete target.
- create a fresh operation generation after you obtain the missing domain, area/context, or user component and rebuild the destination, and compare its final state with the failing run.
The result diagnosis is strongest when object state and protocol trace share timestamps and transaction identifiers; when diagnosing it, avoid treating packet capture and HRESULT logging as substitutes for one another.
Actions that do not address this condition
- An investigation should not 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.
- Do not discard the result facility and state boundary when converting the result into application telemetry.
Remediation boundary
Resolve it at its producing layer: obtain the missing domain, area/context, or user component and rebuild the destination; after it, a separate UI or watchdog retry must wait until that layer reports a final state.
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 phone-style URI is submitted without the domain or dialing context needed by the gateway.
Verification after a fix
A useful it regression does more than expect an exception; the result test constructs “the Request-URI lacks information required to identify or route the destination”, checks the exact HRESULT at the producing RTC boundary, and verifies state ownership before and after the targeted correction.
