The following are some of the major clients we have worked for over the years (most recent first):

Miton Systems is our sister company, and develops flexible telephony systems based on the open-source Asterisk platform which runs on the Linux operating system. Examples of these systems include:

  • A cluster of eight custom conference bridges with interactive control, dialling of participants and recording of conferences, for use by US government agencies.
  • A pair of 120-channel conference bridges for BT. In the first year of operation, one of the bridges handled over 10 million minutes.
  • A pair of custom conference bridges for Starhub in Singapore, providing a blast-dial facility to multiple recipients, with recording.

MB Consult Ltd is a consultancy in microbiology with clients all over the world. They needed a new office computing platform that would support desktops and laptops with shared data and email that could be accessed seamlessly whether in the office or working remotely. We specified, installed and continue to support a system as follows:

  • An office server running Windows Small Business Server 2003 including Microsoft Exchange.
  • Two desktop clients and two laptops.
  • Remote VPN access.
This has been running very successfully for several years.
