Changelog

1.0.0 — 2026-08-13

Initial build on mail.txt3.net (Debian 12, Asterisk 20, Apache 2.4, Postfix).

  • Transcription: per-voicemail mailcmd (vm_mailcmd.py) transcribes the attached recording with faster-whisper base.en (CPU, int8, VAD-filtered).
  • Summarisation: local extractive summariser with intent tags and spoken- digit callback-number extraction. No LLM, by choice.
  • Email: rebuilt multipart/alternative notification (plain + styled HTML) with the recording attached; relays the original Asterisk message unchanged on any error (fail-safe).
  • Telegram (optional): per-mailbox routed voice-note DM with summary caption and transcript follow-up; degrades sendVoice → sendDocument → sendMessage.
  • Contacts (optional): caller-ID → name via file (vCard/CSV export), google (People API OAuth), or carddav (app password; Nextcloud/Fastmail/ iCloud). Last-9-digit matching. Note: Google app passwords do not work.
  • Web portal: FastAPI app at https://vm.txt3.net — PIN login (mailbox + voicemail PIN from voicemail.conf), list, play, download, delete, per-user settings. Zero JavaScript, script-src 'none' CSP, loopback-only backend behind an Apache TLS reverse proxy. Brute-force lockout per (mailbox, IP).
  • Storage: SQLite store with content-addressed audio (decoupled from Asterisk's renumbering) and DB-backed sessions.
  • Backfill: vm_import.py imports and transcribes existing spool recordings; idempotent on (mailbox, origtime, callerid). Backfilled 157 historical messages on first run (3m40s, 0 failures).
  • Packaging: venv at /opt/vm-transcribe, systemd vm-portal.service, Apache vhost + certbot TLS, install.sh.
