-; `notice` is KEPT, deliberately. Asterisk logs rejected SIP requests at
-; notice level via log_failed_request ("No matching endpoint found",
-; "Failed to authenticate"), and on a box whose whole job is answering SIP
-; those are the single most useful diagnostic. Dropping notice made the log
-; quieter and the gateway undebuggable — a call was refused and nothing said
-; so.
+; Warnings and errors only. That covers what matters when a lab call
+; misbehaves: failed authentication, no-matching-endpoint, playback failures.

-; `verbose` is excluded: dialplan execution ("Executing [1001@...]") is
-; useful when tracing a specific call, but it is not worth shipping to Loki
-; continuously. Raise it at runtime instead:
+; `notice` and `verbose` are both excluded because the "Remote UNIX
+; connection" pairs the healthcheck generates arrive on those channels, and
+; they swamped everything else (the Loki stream measured 100% healthcheck
+; noise before this). The healthcheck itself is also reduced to one CLI call
+; on a 60s interval in docker-compose — the two changes work together.
+;
+; To trace a call's dialplan execution, raise verbosity at runtime rather than
+; leaving it on:
 ;     asterisk -rx "core set verbose 3"
-;
-; The healthcheck's "Remote UNIX connection" pairs also arrive on notice.
-; They are dealt with at the source rather than by silencing the channel:
-; docker-compose replaces the image's ~7-connections-per-30s healthcheck with
-; a single check on a 60s interval, and modules.conf stops the container
-; loading hardware and database modules it has no use for (~74 ALSA lines per
-; restart). Those two together cut the noise without costing visibility.
