IP Address Ranges

Voxbone provides call forwarding via SIP to an IP address or a SIP URI.

For redundancy reasons we ask our customers to configure all SIP and RTP ranges below in order to receive calls on their gateways. In case of an outage, we may reroute the traffic from any other PoP, which is also why incoming traffic must be allowed not only from the default PoP, but from all other PoPs as well.
