… session The security fix in #17576 tightened unauthenticated access to getSettings(), breaking SIP bridge connections. The SIP bridge is a headless service with no userId that authenticates via HMAC headers (talk-sipbridge-random / talk-sipbridge-checksum), which getSettings() was never taught to recognise. Mirror the existing recording-backend detection block: validate the SIP bridge headers when present, return 401 + brute-force throttle on failure, and allow the no-token neutral-point path when the request is authenticated.
