Phone system technology has advanced considerably in recent years.  Innovation within the telecom industry now means the way we communicate both at work and in our social lives is now almost unrecognizable from just two decades ago.

It wasn’t too long ago that a multi line phone system was one that had to operate from a switchboard that directed the caller to the right phone line. An alternative multi line system was simply the placement of multiple phone sockets around an office space.

However the technologies that now support modern day multi line phone systems offer greater flexibility, improved call quality and no requirement for vast amounts of equipment. This is a huge advantage for small businesses looking to compete with larger competitors with the use of a multi line system.

Advantages of Multi Line Phone Systems for Small Business

The key advantage to a multi line phone system is that your business open a number of communication channels with key stakeholders at the same time. There is nothing worse for your customer service standards than to have an irritated customer calling to find they are met with a ‘busy’ tone.

One of the main benefits of a multi line phone system is that you can connect several lines to each phone allowing colleagues to transfer calls or switch phone lines with a simple press of a button. If you need to make an urgent telephone call but a colleague is already on the phone, all you have to do is press a button on your telephone to take up an available line.

Call waiting features are also available on many multi line phone systems. Employees can place a caller on hold while also taking an incoming call. Call forwarding can be set up so if a member of staff is away at a meeting or annual leave, their calls can be re-routed to another colleague during their absence.

The setup of a multi line system is super simple. No complex hardware to maintain and a customizable user interface, small business owners are in full control of their systems.

Traditional telephone systems have a dedicated line so moving premises means a whole new set of phone numbers which can cause problems. With the multi line phone system, your phone numbers go with you as many of the systems use IP connectivity.

There’s nothing worse than having a poor quality line when you are having an important conversation with potential customer. With a multi line system, clarity is improved which significantly enhances the call quality for both you and the caller.

How Multi Line Phone Systems Work

Multi line phone systems operate in a similar way to a regular phone, but the lines have been split. Once the lines have been split it allows a business to connect two phones into the same telephone but each function independently. A multi line phone features an extension so additional phones can be attached. In the majority of instances, both phones will ring at the same time and the call can be picked up at either location. Some systems allow for one phone to ring and the other to display a flashing light.

Using a multi line splitter, the phone line will be separated into two or more lines so more phones can be added. A splitter is connected at the telephone socket and requires nothing more than some additional cables.

Choosing the Best Multi Line Phone System for  Your Small Business

When managing a small business you need a phone system that you can rely on but there are several things that you should take into consideration. This could be something as simple as the telephone number right or how much it’s all going to cost through to addressing more complicated business requirements such as supporting your business or incorporating features such as voicemail, call divert and caller display.

Any type of multi line phone system whether it’s has a two line or four line capacity would bring a number of benefits to your business because they can significantly improve communication channels, support your existing processes and are flexible enough to adapt as your business grows.

 Cost – Any small business understands that every penny counts. With a multi line phone system, the cost of calls are usually much lower than a standard phone line, this is usually because many of the multi line systems now operate through the internet. In addition, telephone numbers are hosted in the cloud so you don’t have to pay costly line rentals and all the system hardware and maintenance is taken care of by the provider leaving you with more time to focus on your business than worrying about a complex technical glitch with your phone system.

 Increased productivity – Multi line phone systems can be routed quickly which increases customer satisfaction and frees up employee time so they can work on other things.

 Professionalism – A small business is rapidly changing. With a regular phone system this can lead to problems, but with a multi line system it will support a busy entrepreneur whether they are working in a shared office and require their own line or from a spare room at home. When a business needs to grow, more lines can be added to the system without having to install a whole new phone network. It also conveys a greater degree of professionalism having a dedicated phone number that customers can contact rather than simply a mobile number.

 Functionality  – Many multi line systems are extremely flexible allowing businesses to add or remove numbers, integrate voicemail, set up call forwarding and much more, offering a far greater range of services than a standard phone system.

 Collaboration – If you have a remote team, a multi line phone system can improve collaboration and maintain communications. Calls can be re-routed to their mobiles meaning that calls don’t go unanswered.

 Customer Service – Using a multi line phone system gives customers confidence. They will recognize that you have a good set up and a strong team who are responsive to customer service requests. Phone lines can make a significant impact on your day to day business operations.

Two Line Phone Systems

2 Line phone systems are ideal for a small company or home based business owner because they feature a range of functions such as voicemail and call forwarding but they can keep business and personal calls separate. A 2 line phone system will have two separate lines with two telephone numbers.

These systems operate by having two separate telephone lines connecting to the same device. Popular with start up businesses or companies who are in the early stages of growth, two phone lines can prove crucial to enhancing customer service and improving communications.

A 2 line phone system will offer a range of benefits to both small start up businesses and medium sized enterprises. A business can enjoy multiple benefits associated with such phone lines because there are multiple ways of handling and processing calls allowing a business to deal with two calls at the same time. This not only facilitates multitasking but it makes a big difference when handling your day to day operations. 2 line phones are also popular with home based businesses because they allow business and home life to be kept separately.

As technology continues to develop, telephone lines are becoming more advanced with the 2 line system being just one of the many improvements in telephone communications. As the years progress, VoIP technologies will continue to develop and other systems will be launched which offer a greater choice of options to communicate effectively with colleagues, customers, partners and suppliers.

Small business owners are more likely to use a 2 phone line system because these types of business are usually in the early stages of starting up and may either use a small home office to manage the day to day operations or work within a shared office. A 2 phone line system will avoid receiving work phone calls on a personal home telephone number.

Larger businesses are able to use a two line phone system to manage different areas of their business such as one for general customer enquiries and then another line to handle technical queries. Within a larger business it is not unheard of for there to be a four, six or even twelve line phone system which has been installed to serve the complex communication requirements of a larger business.

Four Line Phone Systems

4 line phone systems are often used for larger businesses or those with small teams, so that each member of the team can have their own telephone line and make use of it when other people are also making and receiving calls. A 4 line phone system could allow 16 telephones to be used, managing 4 incoming or outgoing calls at the same time. It is important to understand how many phone lines your business needs before you start purchasing anything so you are not investing money in something that you don’t need or paying for extra lines that are going unused.
