      The provider's Postman collection is described as covering both sandbox and
      production. The public spec declares a single production server
      (https://api.frejun.ai); a distinct sandbox base URL was not found on
      public surfaces.

      No published test phone numbers, test cards, or fixture tokens found — Teler
      is a voice/telephony API rather than a payments API, and testing is done
