  • Customer is then transferred to a team, of advisors who will take their details.
  • You can then receive these messages from us via mobile, fax or email at half hour or hourly/2 hourly intervals, the choice is yours.
Voicemail option
  • A divert service will route all calls to our voice mail service
  • You will have the ability to personalise the voicemail to your liking
  • You can then  access your messages remotely with your own personalised PIN number

Services

  • BT offers a range of digital services for ISDN30/30e which provide advanced call-handling features

ISDN applications

  • You can use ISDN for voice calls and for high-quality data links with other ISDN subscribers. Digital connections are often used for transferring large files securely, for video-conferencing and for linking Local Area Networks at different sites
  • You can make data calls to other countries that have ISDN services

Internet

  • If ADSL is not yet available in your area, you can connect to the Internet at 64kbps using one ISDN channel, or at 128kbps using two channels together. Since each channel is a true 64k connection, you will find that even one channel performs significantly better than a 56k dialup connection. (For an analogue dialup modem, 56k denotes the maximum speed possible, not the average connection speed)
