System Resilience

Multiple Site Data and Voice Backup and Redundancy

Multiple locations in Wandsworth, Docklands and Suffolk ensure voice and data services run 24/7 with a higher than average industry up-time, maintaining services well inside SLA expectations. Bypass of external and 3rd party failure is achieved through extensive backup and duplication of systems. Call loads are distributed effectively to ensure service continuity.

Docklands and Suffolk Interconnects

Voice and data network resilience - Multiple site system redundancy
On failed connect, routing at the BT Interconnect Switch provides fallback routing to London ISDN, London SIP or Framlingham geographic routes, for X-on provided numbers.
Traffic can be routed via SIP to the alternative site in event of congestion or failure. Load balancing switches route traffic to the least busy IVR switches and can provide carrier pre-selection on outbound routes.
If any IVR fails, load balancing switches will reroute traffic. Multiple redundant IVR switch servers share data from file server and synchronized database resources.
