Enabled by our SmartPacket™ technology, Horizon offers VoIP from only 2kbps compared to around 8kbps from other VoIP services today.

Fully compatible with digital telecommunications standards, it is capable of interconnecting any phone system over IP – on mobile, fixed and satellite
Horizon is a complete end-to-end solution for operators and service providers.

It enables low-bandwidth VoIP based on SmartPacket™ technology via smartphones, PCs, analogue and digital fixed phones.

We provide all the necessary elements for you to build and operate your own Horizon network or we can host the service on your behalf.
Traditional VoIP calls send the same amount of data in both directions, regardless of whether someone is speaking or not.

Horizon is designed to detect silence and send “heartbeats” instead of data, so you know the line hasn’t been dropped. And those heartbeats get sent at only 0.25kbps. Hardly a breath..
