No. Trial numbers cannot be used for inbound call connectivity. Incoming routing is available only on active, fully provisioned numbers on a verified account.

​
Why are inbound calls blocked on trials?

To comply with telecom regulations and prevent abuse, trial numbers are sandboxed. They are provided so developers can test outbound API connectivity, WebRTC signaling, Voice XML execution, and webhooks in a controlled environment. Opening inbound routing to unverified accounts would expose the network to potential toll fraud and routing manipulation.

​
How to unlock inbound calling

If you have successfully tested your application for outbound and are ready to map incoming calls to your SIP URI or webhook URLs, you must upgrade your account:
1

Open your dashboard

Navigate to your Vobiz Dashboard.
2

Complete KYC verification

Complete the KYC Verification process (GST for organizations, Aadhaar/PAN for individuals).
3

Add a payment method

Add a payment method and purchase a dedicated incoming trunk or DID.
4

Configure routing

Configure your newly provisioned number to point to your Voice XML application.
Developer Tip: While you cannot receive external carrier calls on trial numbers, you can simulate inbound webhooks and test your backend application logic by directly hitting your server’s endpoints using tools like Postman or curl with our standard JSON payload format.
