Frequently Asked Questions

Is VoIP legal for businesses in India in 2026?

Yes — VoIP is legal in India for businesses. However, VoIP-to-PSTN (calling regular phone numbers) requires a licensed PSTN provider (Tata, Airtel, Reliance, etc.) for the last mile. All platforms listed use licensed Indian PSTN carriers for call termination.

Can I port my existing office phone number to a VoIP system in India?

Yes — Indian mobile numbers and landline numbers can be ported to VoIP platforms. Number porting takes 3–7 business days and requires NOC (No Objection Certificate) from the current carrier. We handle number porting for clients across Delhi NCR and major Indian cities.

What internet speed is needed for VoIP calls in India?

Each simultaneous VoIP call requires approximately 100 Kbps. For a 20-person office with 10 concurrent calls, 2–3 Mbps dedicated for voice is sufficient. We recommend a leased line or dedicated broadband for VoIP — shared home-grade broadband causes call quality issues.
