    Voice API FAQs

    Frequently asked questions about voice APIs, billing models, delivery, and regulatory compliance.

    Technical

    How does call routing work?
    Calls are routed using intelligent operator selection based on geography, call type, latency, and historical ASR. Automatic failover ensures high availability.
    What call types are supported?
    We support IVR, outbound dialing (OBD), missed call, voice OTP, click-to-call, and AI voice agent workflows.
    What is average call setup time?
    Average call setup time ranges between 300โ€“800 ms, depending on operator and destination.
    Do you provide real-time call status?
    Yes. Call events (initiated, ringing, answered, completed, failed) are delivered via webhooks and dashboard analytics.

    Billing & Pricing

    How is voice billing calculated?
    Voice calls are billed based on pulse duration (15-second or 30-second slabs) depending on route and contract.
    Are failed calls charged?
    Failed calls that do not reach the handset are not charged. Partial charges may apply if the call is answered.
    Do you offer volume discounts?
    Yes. Enterprise pricing is available based on monthly call volume, concurrency requirements, and SLA commitments.
    Is prepaid or postpaid available?
    Both models are supported. Prepaid is instant, while postpaid requires KYC and credit approval.

    Compliance & Security

    Is the platform TRAI & DLT compliant?
    Yes. All India voice traffic follows TRAI regulations and DLT-mapped entity validation where applicable.
    How do you handle DND and consent?
    DND checks and consent enforcement are automatically applied based on call type and regulatory requirements.
    Is TCPA compliance supported?
    For US traffic, TCPA rules such as calling windows, opt-in handling, and DNC enforcement are applied.
    How is user data protected?
    All APIs use TLS encryption. Data is masked, access-controlled, and retained based on configurable compliance policies.
