Every small business owner wants what is best for their enterprise. But when it’s time to invest, most put their money into product development, company talent, online marketing, etc., which is still great and helpful for your business’s growth. However, if you want to ensure that your enterprise can compete with others, along with the big picture, you will also need to look at the small details holding you back.

For example, great customer support is crucial if you want to keep your clients happy. You will need more than professional, trained employees to provide quality customer service. Small business owners have to also invest in the best technology equipment not to offer their clients a poor call experience.

Not being able to handle too many calls at once will cost you sales and damage your reputation. If, with your business’s growth, you also have a growing number of simultaneous calls, it’s time to put money into a multi line phone system. A multi line phone system such as a VoIP provider is the best approach for customer calls. In this article, we will discuss everything you need to know about multi line phones, including:

  1. What are multi line phone systems
  2. Why choose a cloud-based phone system?
  3. Features of multi line phone systems
  4. Types of line phone systems

What are multi line phone systems?

The difference between phones with a single line and multi line phone systems is that they can maintain more than a phone call at a time. When the call center agent is in line with a customer and another one dials your number, callers will be directed to another agent, a voicemail, or a busy signal.

But a multi-line phone system does much more than just hold calls. It can also dial internal and external numbers or return to the line. Multi line systems have one caller ID assigned to them. You will also not need phone jacks.

The two main ways to set up a multi-line telephone system are:

  • On-premises multi-line phone system—This type of line phone system requires telecom hardware and some technical experience to be managed in the right way. It is the more traditional, standard phone line. Some types of on-premises phone lines systems are Private Branch Exchange (PBX) or Key System Unit (KSU).
  • Cloud-based multi-line phone system—This is a more modern, recent version that needs less on-site hardware and offers more scalability. Examples of cloud-based systems are VoIP phone services and a few IP PBXs.

Why choose a cloud-based phone system?

Best multi line phone systems

This phone system is the most used because it is more flexible, less costly, and has more features. There was a time when only huge enterprises could afford the more traditional system as it needed more room and was more expensive. The cloud-based phone system made it possible for small businesses to offer customer support.

A cloud-based phone system converts calls into data and then proceeds them to a local data center. This business communication solution saves you space because it is hosted in the data center and doesn’t take up space like the bulky hardware of traditional phone systems. It doesn’t even need physical landlines as it exists in the cloud and uses virtual phone extensions.

On the contrary, an on-premise business phone system requires more maintenance and extra repairs. The hardware upgrades require additional expenses, and the new extensions need new cabling and installation. Even the implementation is expensive and complex. Only people specially trained for it can help with its maintenance.

Meanwhile, a cloud-based phone system doesn’t require dedicated personnel to help with its maintenance. Changes can be done instantly, and upgrades are done automatically. Even the installation is quick and only takes you some minutes.

You won’t need to be in the office to answer incoming calls because the VoIP phone system can even be accessed from anywhere through a personalized account. The service provider connects the calls to the recipients over an internet connection. This allows customer service agents to work from their homes remotely.

Another benefit of the VoIP system is that it provides unlimited phone lines and doesn’t need on-site users to reach a dial tone. Despite the differences, a VoIP provider offers great call quality, just like the on-premises phone system.

Features of multi line phone systems

When choosing a multiple line phone company, be sure to pick one that offers all the basic functionalities.

1. Call forwarding

A multi line phone system can automatically transfer calls to another user or device. Some VoIP providers even allow you to forward calls to your voicemail or desk phone. It is beneficial when you are out of the office to transfer the call to another coworker and not suffer from missed business opportunities.

2. Call recording

Call recordings are much needed to train your team and provide insights into the customer’s most usual problems. New agents can listen to calls made by more experienced employees to understand what to do and what not to do in a call with a client. They are also helpful for call quality controls.

3. Toll-free numbers

Toll-free numbers don’t charge the person calling the line. They are also helpful for long-distance customers that want to reach your business but don’t want to pay fees for the call because they are out of your area. The US 1800 numbers help you build trust within your audience.

4. Voicemail

It may happen that you can’t pick up the call on time. In this case, you can allow the client to leave a voicemail and even get transcripts of it sent to your email. This helps you not lose a possible customer that can turn to your competitor if you don’t answer their request for insights.

5. Call analytics

The best decisions you can make are data-driven. Call analytics can help you by providing track metrics average wait time, number and percentage of missed calls, average talk time, total cases, etc. Call recordings are also not the only feature that helps value the quality of a call because call analytics show volume patterns as well.

6. Call routing

This feature directs callers to the correct department that can answer their questions. You can define the criteria for which person to answer specific calls. You can choose skill-based routing, chronological order routing, etc.

Types of line phone systems

There are more types of line phone systems than just one. Which one you should buy for your small business depends on the number of employees in your customer service department, how many calls a day your company has, how much your agents can handle, etc. Most small businesses use up to four lines.

2 line phone system

This is the most common type for small businesses that have just started. This system is also used by people who want a personal number separate from their business number. This helps add a more professional tone when a customer calls. Independent contractors or freelancers use this phone system the most because they answer business calls themselves as they are in a moderate volume.

4 line phone system

This system is used by medium-sized enterprises with a team answering calls regularly or for contact centers. A four-line phone system is helpful for employees that need a dedicated line and the rest of the team that needs shared lines. This phone system is also used by receptionists who need to put calls on hold and use call routing.

6 line phone system

Most small businesses don’t need a 6 line phone system as bigger enterprises use them. But some SMEs may need a dedicated line for the fax machine, a phone line for each member, and a phone line for the manager.
