Business Phone Line Overview


Business phone lines are an affordable communication solution for small businesses that allow you to grow your company, establish solid relationships with clients and suppliers, as well as reduce your current phone costs.

Now, I know what you’re thinking.

Wouldn’t it be cheaper to conduct business using your phone line?

Not necessarily.

Even for a new startup, business phone lines offer crucial services such as unlimited domestic calls, discounted international calls, and telecommunication capabilities that aren’t available on regular phone lines.

Plus, providers offer business phone line packages at extremely affordable rates that usually range from £15 to £25 per month. The total cost depends on how many lines you need, the calling capacity of your solution, and what additional features you purchase.

A business phone line allows you to obtain a unique phone number that establishes your business’ identity. Clients and suppliers will associate this number with your company, which makes it all the more critical for you to select the best provider possible.

I’m guessing you have noticed that technology has allowed a lot of business to be conducted through the Internet, with clients and suppliers never having to interact with you. This makes you doubt the need for a phone at all, but the truth is that speaking over the phone always establishes a more personal connection, which only strengthens your relationships and solidifies your business’ reputation.


Business Phone Line Benefits


So why do you need a business phone line?

Business phone lines provide a cost-effective communication solution with call packages that essentially allow you to make and receive more calls at an overall cheaper rate. What this means is that you can effortlessly keep in touch with your clients and suppliers, without worrying about the minutes adding up or pesky long-distance charges.

Furthermore, you’ll be glad to hear that some providers such as BT include unlimited calls within the UK, as part of their monthly charge. Other providers give you the option to purchase unlimited calls within the UK, or even overseas, for a very affordable rate.

Besides cutting down your costs, business phone lines also have many features that are incredibly useful if you want to streamline and improve communication.

For example, call management is a popular feature that allows you to customise the parameters of your telephone calls so that when someone phones in, they are automatically directed to the appropriate person or department.

Modern business phone lines, such as ISDN or Integrated Services Digital Network, utilise digital networks which allow you to operate multiple tracks at the same time. This means that multiple employees can be reached through the same business phone number that represents your business. ISDN or multi-line systems are ideal if your business is involved in sales or is a call centre.


Business Phone Line Costs


Fact: Business phone lines aren’t expensive.

Yes, you read that right.

Total monthly costs generally range from £15 to £25 per month, depending on your phone package features, additional services, and the volume of calls you plan to handle.

You’ll find that the initial costs are:

  • Installation fee
  • Monthly line rental charges
  • Calling charges

And good news! Since you are purchasing a phone line and the technology that comes with it, you won’t face the hefty costs of purchasing extra hardware. Your business phone line is quickly installed into your office phones, and you get back to business right away.

If you choose to purchase additional features and services to enhance your business communication, you’ll pay a monthly fee for each of them. But don’t worry. In general, the costs of using additional features only runs from £1 to £10 per month, depending on the complexity of the service.

How to Select the Right Business Phone Line


To select the best business phone line for your business, you need to know about the different types. This will ensure that you avoid costly mistakes by having a good understanding of what business phone line you want.

The two primary types of business phone lines are PSTN or Public Switched Telephone Network, and ISDN or Integrated Services Digital Network.

PSTN is the traditional version of business phone lines and uses analogue signals to transmit your voice communications. PSTN lines only allow one call per line at a time, which means that it’s best suited if your business operates out of your home, or is very small. It is the simplest form of business phone lines and is the ideal solution when you don’t require a lot of lines and extra features.

ISDN phone lines digitally transmit your voice, video, and data using a broadband connection which offers more capabilities and features than PSTN lines. Most importantly, ISDN allows more than one call per line at a time, which means that it can easily scale as your business grows.

There is a variety of ISDN versions, such as ISDN30 which is suitable for larger businesses as it allows you to access over eight channels through your business phone line.

Right, now that you’ve covered the different types of business phone lines, what are the things to look for?


Here’s a simple list of the main things to consider when you select a business phone line:

  • Cost-effectiveness

Make sure that your business phone line cuts down your current phone costs.

  • Customer support

Your provider should offer accessible, effective, and fast customer support because when you are faced with a communication problem, you need to be able to fix it fast.

  • Broadband speed

If you are using a digital or ISDN phone line, check that your broadband is capable of handling calls without sacrificing quality.

  • Scalability

Always have a plan for the future by ensuring that your business phone line can scale as your business grows. You may need to handle more calls and require additional features to improve collaboration and communication between an increasing number of employees.

  • Features

Make sure that all your business communication needs are met by your business phone line, through the features and services offered in your package.

  • Contracts

Consider if you want to be tied down in a long-term contract, or if your provider requires a minimum period of usage.
