Telephony and Number Provisioning

Telecom Plumbing Handled Directly Inside the Platform

In India, outbound calling regulations require strict adherence to telecom guidelines, identity verification, and number reputation management. Many voice platforms force businesses to bring their own Twilio or Exotel credentials, complete external carrier KYC, and reconcile multiple bills.

With CallUltra, telephony and number provisioning are integrated directly into the product. We help your team select, provision, and maintain dedicated business numbers with zero external carrier headache.
