[MediaProxy]

; so the summary can localize a break to which side of MediaProxy it dies on.
; Set the MediaProxy relay host; that's all that's needed — the per-call RTP
; PORTS for this leg are negotiated in the SIP SDP and vary per call, so we
; filter by host only (no port range). The WebRTC leg's exact ports always come
; per-call from Janus ICE. Leave unset to skip this leg.

; Optional PEER PROBE — a second sylk-qos-server running ON the MediaProxy
; host (same daemon, install with [Janus] mode = off there). When set, every
; call is also registered on the peer, which counts the same Janus<->MediaProxy
; RTP tuple at the MediaProxy NIC. The finalized summary then contains a
; hop-by-hop loss analysis that can tell apart:
;   - loss ON THE WIRE between MediaProxy and this host (per direction),
;   - loss INSIDE this host (arrived at the NIC, never relayed),
;   - loss AT/BEYOND MediaProxy (far end -> MediaProxy),
