Network Quality of Service

Our customers recognize Voxbone as the leader for quality of service, in terms of availability, audio quality and call success rate. The following elements contribute to our best-in-industry quality of service.

Switching and routing equipment

Voxbone uses carrier-grade routers, switches and gateways from established vendors (CiscoDialogic, and Juniper) throughout its entire network. For its core network switching and application logic, Voxbone relies on a unique mix of open-source software and applications from industry-leading vendors, complemented with proprietary software. Voxbone strictly adheres to the SIP standard and is an active member of the SIP software community. The company has developed several in-house, high availability mechanisms that have been adopted by other software developers or are in the process of becoming official Internet Engineering Task Force (IETF) Request For Comments (RFCs).

24/7 support

Voxbone offers 24/7 support to its customers via a web-based ticketing system. Our US- and Belgium-based support teams work in shifts to ensure round-the-clock support, with ticket transfer and escalations procedures in place. All critical IT systems, as well as core and edge network components, are monitored proactively to ensure prompt resolution.


Redundancy is built-in at every level of our network.

  • Network redundancy: If any private backbone link fails, the internal routing protocol reroutes calls over a backup link in less than two seconds.
  • Systems and database redundancy: All critical systems are configured in active/standby pairs for immediate and stateful failover in case of failure. 
  • Signaling redundancy: The signaling proxies are configured in active/standby mode with execution of failover in seconds.
  • Hardware redundancy: Each Voxbone region is equipped with multiple VoIP switches and media gateways to mitigate the risk of hardware failures.
  • Data center redundancy: In case of a complete outage in one of Voxbone's core data centers, all traffic is immediately rerouted to another data center.
  • NOC redundancy: Two geographically separate network operation centers (NOCs) are located in Brussels, Belgium, and Los Angeles, California.
