Types Of Business Lines…

There are a variety of phone lines currently available to your business, each holding different qualities which are best suited to different types and sizes of business.

In order to know the type of phone line that is going to be most beneficial for your business, you must first consider how the phone lines are going to be used.

To help you with your decision, we have provided a brief description of each of the phone line types, below:

  • Analogue Single Line – Works from the local exchange, suitable for smaller businesses with just one phone
  • Analogue Multi Lines – Also work from the local exchange, but allow multiple calls through one number
  • ISDN2 Lines – Digital line, allows up to 8 different channels (extensions)
  • ISDN30 Lines – Like ISDN2, but allows up to 30 different channels (extensions)
  • SIP Trunk – An alternative to ISDN lines, Sip Trunks connect to your existing PBX using either an IP Card or IP Gateway converter.
  • FeatureLine – ‘Mini’ telephone system based at the local exchange, offers features such as ‘conference calling’ and ‘call divert’ for compatible phones.


At 5G we recognise that every business is unique and that different types of business will require different types of phone lines. For this, we are more than happy to discuss your business phone line requirements with you, but to give you a general idea of the suitability, of each of the phone lines, we have provided a short summary, below:

  • Small Business – Analogue (single/multi), ISDN2
  • Small/Medium Business (High Telephony use) – ISDN30
  • Large Business – ISDN30, FeatureLine

Business phone systems can be expensive, and for many business owners, voice over internet protocol (VoIP) is a viable option at a lower price. Using VoIP instead of standard land line service might sound like a strange idea, but when you think of how many phone lines you might need for your business, and the cost associated with them, it might be time to give it a try.

With VoIP, you’ll still need to get however many phone lines you need to run your business, but the cost is often less than going with the traditional phone company.

Even the most digital businesses need phones. But these days it’s about much more than chatting. As your workforce grows and disperses, you want to be able to feel like you’re together, even when you’re not. And you want cheap bills, too.

New landlines clearly aren’t the answer – they’ll soon be defunct anyway. So, what do we do? We VoIP! We digitise voice into data so we can ditch our landlines. All you need is the right internet connection.

VoIP could save you a lot of money but you’ll need enough bandwidth to make the most of all its features. As long as you have the right connectivity, you can join your business colleagues on media-rich conference calls, and share work on screen as though you’re right there.

The new landlines (and then some). When you’re more productive, your customers feel it too.

Plus, now you can auto-reroute at busy times, and answer customer service calls from home. Your customer service is better, and that means more recommendations. And best of all: no more hideous hold music.

Can I access the internet over an ISDN line?

It is possible, but not advisable. Years ago, before the introduction of DSL broadband services it was not uncommon for people to use ISDN lines as a faster alternative to dial up internet. But now with DSL broadband, so much faster at affordable prices, there is no real need to do this.

What is the difference between ISDN2 and ISDN30?

The only difference between the two is the number of channels/terminals that each can support. ISDN2 lines can support up to 8 channels whereas ISDN30 can support up to 30 channels, significantly more than ISDN2.

Once I make the change over to 5G, how long will it take for my services to become active?

When signing up new customers, we generally quote between 7 – 14 working days for analogue phone lines and between 10 – 25 working days for digital phone lines.

What should I do about leaving my current provider?

We want to make your move over to 5G as quick and as painless as possible so we will strive to help you as much as we possibly can to ensure that leaving your current provider isn’t going to break the bank.

Will I save money with 5G?

Yes. If you sign up with 5G, we guarantee to save you at least 10% on your current bill.
