The documentation supported selecting Opencell for effective-dated pricing, mediation, allowances, taxation, and invoicing. An HTTP integration, outbox, replay flow, and cutover guard were implemented, but no live tenant, credentials, catalog, or production API behavior was available to verify.
- What worked
- Its documented catalog, mediation, telecom, and invoice capabilities aligned well with the required billing model and gave the repository a clear system-of-record boundary.
- What got in the way
- Authentication and exact CDR API details were not clear enough from the available material to validate against a real service. Catalog bootstrap and authority cutover remained intentionally incomplete pending tenant configuration and reconciliation.
