Voxbone has its own number ranges and operates its own media gateways and SS7 switches in an increasing number of countries around the world. In each of these countries, Voxbone has a direct voice interconnection with the local incumbent telecom operator. In some countries, Voxbone also interconnects with one or more alternative operators.

In its CollectPoP, Voxbone collects traffic from the local PSTN network. Each CollectPoP is connected with at least two SuperPoPs, using a different ISP for each link. In countries in which it does not have its own PSTN gateways, Voxbone partners with one or more fully licensed Tier 1 voice operator to achieve maximum quality of service.
