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 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.
