Two bugs tracked to the same root cause: the media-server's recorder was writing both the customer and agent RTP streams into a single oggwriter. The two streams have unrelated SSRCs, sequence numbers, and timestamp bases, so the resulting OGG carried non-monotonic granule positions. Browsers compute duration from granule positions → the audio element reported inflated times. Whisper parsed the broken container and returned garbage, which showed up as nonsense transcripts. media-server changes - Recorder no longer writes to a combined oggwriter during the call. Each direction is captured into its own clean OGG (customer-only and agent-only). - At Finalize, the two files are mixed with ffmpeg into a single combined.ogg that has coherent OGG pages and correct duration. If ffmpeg isn't on PATH we fall back to the customer-side file alone so the pipeline doesn't break on bare hosts. - GET /sessions/:id/recording now accepts ?side=customer|agent so Rails can fetch the per-direction files for diarization. Rails changes - MediaServerClient#download_recording takes a `side:` keyword. - CallTranscriptionService prefers per-side transcription when the session has a media_session_id: downloads both files, runs Whisper with response_format=verbose_json for segment timestamps, interleaves by timestamp and labels lines Customer: / Agent:. Falls back to the combined recording if per-side downloads fail. - Lowered Whisper temperature from 0.4 to 0.2 for more deterministic transcripts. Setup: ffmpeg is now required for correct combined playback and transcription. Install on macOS with `brew install ffmpeg`; on Linux install the distro's ffmpeg package.
