Telephony

Connect your Plivo, Twilio, Vonage, or Telnyx account to use for outbound and inbound PSTN legs. Rymi encrypts provider credentials before storage.

Self-serve BYOC carrier costs are not bundled into Rymi's platform minute price. Your carrier bills PSTN minutes, number rental, taxes, and add-ons directly. Rymi bills at the agent's per-minute rate: its managed SKU price, or for a custom agent the stack's component cost plus the flat $0.02/min platform fee. Enterprise plans can bundle telecom under a custom agreement.

List Available Providers

GET/v1/telephony/providers

Returns the full carrier catalog with the credential field shapes the dashboard uses to render dynamic connect forms. No auth required, since field metadata is not sensitive.

Response 200

  "providers": [
    {
      "id": "twilio",
      "displayName": "Twilio",
      "credentialFields": [
