No need to employ expensive support staff

Teleswitch is maintained by Zimo's dedicated engineering and operations teams, managing the network to deliver the stability, resilience and availability upon which your customers depend. Backed by rigorous Service Level Agreements, Zimo deploys some of the most sophisticated network monitoring, fault detection and alerting tools available. These advanced warning systems allow for automatic and seamless switching between networks in the unusual event of a fault being detected.

Handle very high call volumes with the emphasis on quality

The Teleswitch Platform is a carrier grade, in house built, 1+1 architecture, modular soft-switch providing high levels of redundancy and resilience. Based upon Open SIPS and developed by our own highly skilled engineering team with many years experience of IP based voice networking, our systems have been specified to handle very high call volumes with the emphasis being on quality. The software is housed on industry leading hardware platforms with full vendor support. The codec utilised by default across our systems is G.711 a-law which not only ensures full and un-compressed speech traffic, it also allows for seamless transfer across the network of fax, something that very often gets overlooked in IP networks.

Extensive back-up and security systems in place

The Teleswitch service is hosted across two geographically diverse locations in Manchester and Maidenhead running in a main/standby configuration.

The primary Teleswitch site (Manchester) is a secure datacentre, housing switching and associated database equipment in resilient dual power fed racks. The site employs UPS and battery backup with a diesel generator able to take complete site load in case of mains grid failure. The site boasts stable temperature control with air-conditioning through a hot and cold aisle air circulation system. Automatic fire detection equipment is provided together with FM200 fire extinguishant should a fire be identified.

The secondary Teleswitch site at Maidenhead also comprises a fully redundant datacentre in terms of power, with dual fed racks, UPS, battery backup and diesel generator providing consistent and stable power delivery. The environment is also air-conditioned and fire detection and protection provided, complementing the services provided at the Manchester site.

The network connectivity between sites is provide by resilient fibre links with internet backup, and is primarily in place to provide heartbeat signals which are exchanged constantly between both sites. These heartbeat signals ensure that all servers are fully synchronised where appropriate (database, softswitch, etc.) and should the primary site fail, the secondary site is immediately available to take traffic from BT and deliver the calls to your partition successfully.

The Teleswitch service can be fully supported at either Manchester or Maidenhead which provides peace of mind in relation to service continuity and provides an inbuilt ability to deal with disaster recovery by design.

Constant monitoring to ensure optimum performance

Our comprehensive in-house configured network monitoring systems are continually being fine tuned to ensure that we are alerted to not only physical element failures, but also changes in traffic profile or signaling cleardown codes. The knowledge gained by managing our own traffic in this way is employed in managing our Teleswitch customers' traffic to ensure that you receive the highest levels of call completion and quality.
