Domestic calling is a better choice than international calling if your calls originate and terminate in India.

​
Overview

If a non-Vobiz IN number is used as the caller ID, calls are processed on a best-effort basis and Vobiz cannot provide support for any issues. For reliable service, use a Vobiz IN number for outbound calls.

​
Advantages

Domestic routing provides several advantages:
  • The call media path is shorter, meaning lower latency and better audio quality.
  • Outbound callers get better recognition with a guaranteed local caller ID.
  • Pricing is attractive, and INR billing is available.

​
Requirements

Businesses must meet several requirements for domestic calling in India.

​
Caller ID

Outbound calls must originate from a Vobiz India phone number as the caller ID.

​
Media anchoring

Media anchoring requires the call media to remain in the same country as the phone call. The media cannot leave the country - calls must both 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 renting India phone numbers or making and receiving calls from your Vobiz account.
