How VoIP works in Onoff

VoIP (Voice over Internet Protocol) routes calls and messages over the internet rather than traditional phone networks. It is the default technology behind every Onoff number.

What happens when you make a call

When you place a call from the Onoff app, the process takes a fraction of a second:

1. Your voice is captured and converted into digital data.
2. The data is sent over the internet in small packets.
3. The recipient's device reassembles and decodes the packets.
4. The voice is played back in near real time.

A stable Wi-Fi or 4G/5G connection ensures clear audio with minimal delay.

What VoIP makes possible in Onoff

One number, multiple devices Use your Onoff number from your smartphone, computer, or tablet — simultaneously, from anywhere with an internet connection.

No roaming charges Calls are routed over the internet, not through traditional telecom networks. International and long-distance calls cost the same regardless of where you are.

Instant scalability Add or reassign numbers directly from the admin console — no SIM cards, no carrier contracts, no delays.

Advanced features Voicemail, call forwarding, SMS, CRM integrations, and cloud-based number management are all enabled by the VoIP layer.

Encrypted communications All calls and messages are encrypted. Keeping the app up to date ensures you benefit from the latest security patches.

Tips for the best call quality

VoIP quality depends on your internet connection. A few simple steps make a difference:

• Use a stable Wi-Fi or 4G/5G connection
• Avoid heavy network usage during calls (streaming, large downloads)
• Close bandwidth-intensive background apps
