Cisco Systems is a global leader in the design and manufacture of IP-based networking solutions. With their European headquarters based in multiple locations, they had business resiliency concerns about sharing common infrastructure. In the event of a single failure to BT’s network, all of their offices would lose voice communications.


Cisco deployed BT smartnumbers to ensure that in the event of a failure, calls can continue to flow. With BT smartnumbers, when network failures are detected, calls are automatically redirected to alternative phone numbers. Calls can also be manually diverted in the event of planned or unforeseen circumstances.


With BT smartnumbers, Cisco has a dependable voice continuity solution with the added benefit of cost reduction. Guy Wychmans, Category Supply Manager, said: “Using BT smartnumbers is much more cost-effective than dual parenting ISDN services and it provides us with far greater network resilience. It is simply a much more flexible and elegant solution.” Additionally, as BT smartnumbers is cloud-based, it enables modifications to be made to internal infrastructure without impacting voice services. For example, Cisco runs IP telephony end-to-end, but for many organisations that is not the case. BT smartnumbers has the potential to make the transition to SIP trunks easier and safer.

“The BT smartnumbers service has allowed us to cost-effectively assure the resilience of our world-class infrastructure.”
