How this service works
An offline SIP stateful-proxy fixture author needs response-context final selection, delayed6xx versus winning2xx races, current-branch CANCEL directives and unchanged anonymous challenge aggregation, including late stateless forwarding.
Output
Returns a validation result indicating whether the claimed SIP fork response-aggregation outcome is correct, covering final response selection logic, delayed 6xx versus winning 2xx race results, CANCEL branch directives, anonymous challenge aggregation, and late stateless forwarding behavior
Example use cases
Verify 6xx vs 2xx race resolution
“I need to verify whether my SIP proxy correctly resolves a fork race where a 6xx response arrives after a 2xx has already won — here's my event sequence with upstream TLS on, one branch downstream TLS, claim 100, and no all-future-503s flag.”
Test CANCEL directive across branches
“Can you check if my SIP stateful proxy correctly issues CANCEL directives to the remaining branches after a 2xx is received on one branch? I have an INVITE scenario with two branches, upstream TLS enabled, and this event log to validate.”
Validate anonymous challenge aggregation
“Validate the anonymous challenge aggregation behavior in my SIP fork fixture — INVITE is true, upstream TLS is false, two branches with mixed downstream TLS, claim set to 500, and here are the branch response events I want to check for correctness.”
Technical details
Endpoint
POSThttps://detect.halowerk.com/v1/F-A-NIGHT-PROTOCOL-SIP-FORK/sip-stateful-proxy-fork-response-aggregation?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify SIP stateful-proxy fork response-aggregation correctness — particularly for offline fixture testing, RFC 3261 compliance checks, or automated regression of fork race conditions (delayed 6xx vs 2xx, branch CANCEL, anonymous challenge aggregation) without requiring a live SIP stack.
Side effects
- Invalid event sequence structure — events array malformed or exceeds 512 items
- Claim value out of allowed numeric range
- Mismatched branch count between branch_downstream_tls array and events
- Missing required fields in sip_fork object
- Contradictory flag combinations (e.g. all_future_requests_503 with active branches)
