Telephone Dialup Call Conferencing

Kingdom Hall Conferencing services are designed to assist the elderly and infirm members of the congregation to listen in to services and meetings, live, via the telephone. However, there are many other applications for this technology.

A Telephone Dialup System (TDS) is simply the safe interface between telephone line and audio source. By adding a conference facility, many more can listen into the audio source by simply calling the conference telephone number.


There are a multitude of different applications for this system:

  • Listen to your local Kingdom Hall live - If you are ill or unable to attend
  • Listen to your Church or Mosque - From wherever you are in the world
  • Share a marketing presentation to everyone on the team - Better audio quality than traditional systems
  • Extend the reach of a training course - Add more attendees
  • Learning opportunities - Children unable to attend schools
  • University lectures - Listen in from anywhere in the world
  • Live events - Allow many more to listen live to the event - Use an 0844 number to raise additional revenues
  • Funeral directors - Allow relatives to listen to services
  • Live translation services - Use a TDS2 and two radio microphones to transmit events in multiple languages
  • This list is endless.........

Reducing Call Costs

This section is provided as a snapshot of what is available at the time of writing. The telecoms market is very volatile so check regularly for new or improved deals.

  • Calls to 0844 numbers (ConferenceGenie) are usually billed at 3p/m - check.
  • Calls to 0845 numbers (OzoneConferencing) cost from 0.5p/m.This depends upon your service provider. For example, TalkTalk charge 0.5p/m for evenings and weekends. BT vary between 0.5p and 2p/m or more - check. VirginMedia are THE most expensive and charge 6p/m or more for access to 0845 numbers! BUT, if you buy phone calls via 18185.co.uk for ANY phone supplier, it may work out cheaper.

You must do your own research to find the best call rates for your particular application. This is a highly competitive market and prices change regularly.
