Empowering and Protecting Critical Telephone Numbers:

Your telephone numbers is an extension of your business brand—an asset and an ambassador to your business. The way you handle these incoming calls is essential for the following reasons:

  • Ensures that during estate rationalisation or office moves, geographic numbers can be delivered easily to any UK destination or to a global site within the BT Global One Voice Network.
  • De-risks infrastructure consolidation that includes desperate platforms, such as SIP and TDM, using both the cloud-based applications and the intuitive business portal.
  • Technology migration and integration projects are eased by separating number management from the connectivity giving total control of call routing to the customer. It is agnostic to network type and operates across PSTN, SIP-T, Featurenet networks.
  • Voice continuity and disaster recovery capabilities through the inherent design of the smart network and business portal.

Network services

BT smartnumbers applications bring the resilience of the core PSTN closer to your corporate network. Without geographic limitation, calls made to your business can now be delivered onto your network (whether Featurenet, IP, TDM, SIP T or Global One Voice) with greater flexibility and resilience than previously available. Calls are delivered for onward routing and call treatment by your corporate voice services. In this scenario BT smartnumbers fulfils the role of ensuring calls made to your staff continue to reach your network if the primary routing or building becomes inoperable. The service will automatically re-route incoming calls upon detection of Network Unavailable (NU) or congestion. Once the problem is cleared, calls will revert back to the primary routing path.

Normal call routing and automatic failover can be over-ridden through any touch-tone telephone at any time. Calls can be forced through either path or in accordance with dial plan data entered through a dedicated web portal.

Each application has its own service description which are available upon request.
