Warning

Use the API (sync), not the CSV. The OVH Manager's CSV import fails past ~80 entries (empirically confirmed). This project exists to push the same data through the OVH API one prefix at a time, throttled and idempotent. The CSV mode is kept for completeness but is not the recommended path.

Quickstart

docker run --rm \
  -e OVH_APPLICATION_KEY=... \
  -e OVH_APPLICATION_SECRET=... \
  -e OVH_CONSUMER_KEY=... \
  -e OVH_BILLING_ACCOUNT=... \
  -e OVH_SERVICE_NAME=... \
  ghcr.io/raedkit/ovh-voip-spam-filter:latest sync

Or via PyPI:

pip install ovh-voip-spam-filter
ovh-voip-spam-filter sync

Generate an OVH token with this pre-filled URL (minimum scopes pre-checked).

Full setup walkthrough: docs/quickstart.

Why this exists

OVH's Manager UI offers a CSV import for the incoming blacklist, but it POSTs each row internally without rate-limiting. The Saracroche list is 643 prefixes — the import returns HTTP 429 after ~80. This tool does the same job correctly: signed API requests, client-side throttle, exponential backoff on 429, auto-adaptation if OVH tightens the quota. One bootstrap run takes ~13 minutes; subsequent runs are idempotent and take seconds.

• Normal mode (Saracroche reachable) — strict sync: adds missing prefixes, removes the ones Saracroche removed.
• Degraded mode (Saracroche unreachable) — uses the hard-coded ARCEP fallback, additive only, never deletes. Anti-regression guarantee.

Details: reconciliation semantics.

Acknowledgments

🙏 This project would not exist without Saracroche by Camille Bouvat.

Saracroche is an open-source community blocklist of ~16 million French telemarketing and spam numbers, maintained solo and pro bono since 2020. We consume the french-list-arcep-operators endpoint as our primary source of truth, with no caching on the redistribution side — the freshness you get is whatever Saracroche has right now.
