Case Studies

Museum of London selects Charterhouse Voice & Data to deliver telephony support that provides resilience and cost savings.

Museum of London

Charterhouse Voice & Data (CVD) deliver telephony support to the Museum of London. By engaging with CVD, the Museum of London have saved around £30,000 each year on their telephony costs, and now benefit from a stable, resilient telephony solution that offers the latest features and functionality.

The Museum of London’s telephony systems were not benefiting from regular software updates, and the incumbent provider was acquired by a larger firm. This resulted in the Museum of London being passed between several Account Managers. There was a feeling that, as a medium-sized not-for-profit organisation, the Museum of London were not a high priority for the provider.


CVD took a highly consultative approach when designing and deploying our telephony system. They were diligent in ensuring that our telephony was fit for purpose, and met our expectations. CVD also trained our in house team, which helps us to help ourselves when we need to make simple changes to the telephony system.” Adam Monnery, Head of IT

Business Design Centre

The Business Design Centre selects Charterhouse Voice & Data to implement a scalable Unified Communications solution that improves customer experience. 

The Business Design Centre (BDC) were running an end-of-life telephony system which failed to meet the functionality needs of their clients, especially those in the high-tech space. The incumbent system utilised three on-premise Mitel controllers, with a Virgin ISDN for connectivity. The business needed to implement a new Unified Communication solution that allowed them to diversify their service offerings, whilst enhancing the level of service they delivered to their clients.


CVD worked with the BDC to understand their requirements and drivers. Using a highly consultative approach, we designed a tailored solution that met and exceeded their business requirements. We have implemented a cutting edge hybrid cloud telephony solution for the BDC. The Mitel MiCloud hybrid cloud solution is clustered with three Mitel physical controllers at the BDC building, allowing for ‘always-on’ availability, whilst enabling the BDC and their clients to easily scale up and scale down services as required.


The Business Design Centre benefitted from the following improvements: 

  • Increased Resilience: the hybrid cloud telephony solution delivers high up-time, and provides resilience in the event of a cloud outage.
  • Diversifying Service Offerings: the BDC can now offer a wide range of feature-rich telephony and collaboration packages to their clients.These packages embrace unified messaging, conferencing, and collaboration.
  • Enabling Agile Working: the solution enables the BDC and their clients to embrace agile and flexible working practices.
  • Higher Client Service Levels: the BDC, and their clients, are able to offer a higher level of service to their respective clients. 


"CVD understood our business needs, and adapted accordingly. No matter our question, big or small, CVD always responded. They were a key fit for our culture, and we had the same great experience no matter who we spoke to." Carly Kling, Property and Communications Manager
