Domestic calling is a better choice than international calling if your calls originate and terminate in India. If a non-Plivo IN number is used as the Caller ID, the calls will be processed on a best-effort basis, and Plivo cannot provide support for any issues. To ensure reliable service, Plivo strongly recommends using a Plivo IN number for outbound calls.
It provides several advantages.
- The call media path is shorter, which means lower latency and better audio quality.
- Outbound callers can get better recognition with assured local caller ID.
- Pricing is attractive, and INR billing is available.
Requirements
Businesses should be aware of several requirements for domestic calling in India.
Caller ID — Outbound calls must originate from the caller ID of an India Plivo phone number.
Media anchoring — Media anchoring requires the media of the call to reside in the same country as the phone call. Simply put, the media cannot leave the country; your calls should originate from and terminate to users in India. If a domestic call leg is bridged with an international call leg, the call will fail with hangup cause “Violates Media Anchoring.”
Business KYC — You must submit know-your-customer (KYC) documentation before you can rent India phone numbers and make and receive calls from your Plivo account.
