Analogue Lines

Our analogue services come in either single or multilines. A single line allows users to make one incoming and outgoing call at a time. With our optional ‘Call Sign’ feature, you can also have two numbers for your single line, which is ideal for users to distinguish between work and personal calls/ multiple businesses calls. Multilines allow users to make multiple incoming and outgoing calls on one telephone number. They can be used individually with phones plugged directly into sockets or attached to a telephone system.


Feature rich  –  All phone lines can come with a range of features, such as call divert or barring, to simplify communication processes and reduce unnecessary administrative work.

Easy setup

Have your phone lines set up in as little as 3 working days. You can also keep your existing number and use your existing phone sets.

Lower costs

Our tailored solutions can integrate your voice and data to reduce your business overheads. Streamline your communication and lower your costs by optimising your communication technology.


ISDN carries your phone line digitally. Our ISDN services come in two forms: ISDN2e – is suitable for offices with 2-8 users. ISDN2 allows you to do two things per line, meaning that you can use one line for data, and another for calls. Channels can also be separated to make two calls at once. ISDN30e – is suitable for larger businesses, ISDN30e can carry 8-30 lines. You can combine your lines to get higher bandwidth and also link multiple offices. You can also make simultaneous calls.


Great call quality Voice and data are carried digitally which means you can enjoy crystal clear, high quality calls, with an instant connection. Fast data Digital lines allow you to transfer data fast and accurately. You can also combine your independent channels to achieve higher bandwidths, supporting your data hungry business apps and tools. Individual numbers for users DDIs/ SNDDIs, which give users individual, unique numbers, can be applied to all digital lines. You can have a series of direct dial numbers without going through a switchboard, streamlining your communication.

How it works

  1. When our customers make an outgoing call, dialled digits are transmitted down the phone line to the local BT exchange.
  2. The BT exchange can recognise the calling party and will then pass the call to the Chess network where the dialled number is analysed for routing purposes.
  3. The call is then passed to the terminating parties’ network provider, reaching the destination network. Call charges are billed to the customer account, which should be paid alongside the line rental charges every month.
