What Is A Multi-Line Phone System?

A business phone system with multiple phone lines allows businesses to simultaneously take and manage multiple phone calls.

This can be highly beneficial for businesses that deal with a high volume of phone calls daily.

With most phones using the DECT 6.0. technology, they can give their users a better range while having the exact power requirements as previous models.

In addition, these systems have been designed to work with each other, so adding more units to the system is a simple process.

Features In A Multi-Line Phone System

The following are some of the key features that a multi-line phone system should have.

Multiple Telephone Lines

It might seem obvious, but the ability to handle a high volume of phone calls is the most critical aspect of a multi-line phone system.

The more available phone lines, the more calls that can be taken and managed simultaneously.

Some systems can have 24 phone lines, while others might be a 4-line phone or even a 2-line phone system.

While startups and small businesses might not need that many phone lines, it’s essential to consider future growth when making a purchase.

Call Waiting And Caller ID

Two other essential features in any business phone system are call waiting and caller ID.

With call waiting, if a business is already on a call and another call comes in, the first caller will be placed on hold, and the phone will display the second caller’s information.

The business can then decide whether to take the second call or not.

Meanwhile, caller ID allows businesses to see who is calling before answering the phone.

This can be a great way to screen calls and only take relevant ones to the business.

Auto-Attendant And Voicemail

A business phone service should also have an auto-attendant and voicemail feature.

An auto-attendant is a recorded voice that answers calls and gives callers options to choose from, such as Press 1 for Sales, Press 2 for Support, etc.

This can be a great way to route calls to the appropriate department or individual.

On the other hand, voicemail allows callers to leave a message if no one is available to take their call.

Coupled with an answering machine, this can be a great way to ensure that no call goes unanswered.

Businesses can then check their voicemail at their convenience and return the relevant calls.

Speed Dial

A phone company that offers a flexible phone system should also have a speed dial feature.

With speed dial, businesses can create a list of contacts that one can call by pressing a single button.

This is an excellent time-saver for businesses that regularly make many calls to the same people.

Dedicated Phone Number

Receiving phone calls on a dedicated business phone line is another essential business phone system feature.

A service provider that offers a dedicated phone number ensures that callers can reach businesses anytime, day or night.

This is a great way to give customers and clients peace of mind knowing that they can always reach someone from the company.

Ethernet Connection

An Ethernet connection is a physical connection that allows businesses to connect their phone system to the internet.

This is important because it allows businesses to make and receive calls over the internet, saving a lot of money on long-distance calls.

Having an internet connection also allows businesses to take advantage of VoIP (Voice over Internet Protocol) features.

Wifi Connection

In addition to an Ethernet connection, a business phone system should also have a WiFi connection.

In some situations, this is even more important because it allows businesses to connect their phones to the internet without using a physical cable through a WiFi system.

Call Forwarding

Call forwarding is a great way to ensure that all calls are answered, even if the business is closed.

For example, if a business is closed for the day, one can forward calls to various mobile phones or an answering service.

This way, customers and clients will always be able to reach someone from the company.

Call Transfer

While some believe this is the same as call forwarding, it’s a different feature.

Call transfer allows businesses to manually transfer calls to another phone line, such as a mobile phone or an answering service – during the actual call.

Call Recording

Having calls recorded is another great feature of a business phone system.

Call recording can be a great way to train new employees or review calls for quality assurance.

Some business phone systems can even transcribe recorded calls, which can be a time-saver in various situations.

Music On Hold

While customers who experience long wait times can become frustrated, playing music on hold can help calm them down.

This is a great way to show customers that their call is important and that the business is doing everything possible to answer it promptly.

Using the main console, this is a feature that one can typically turn on and off at the press of a button.

A Suitable Softphone

A softphone is software that allows businesses to make and receive phone calls through their computers.

This is an excellent way for businesses to save money on long-distance calls and take advantage of features like call forwarding and call waiting.

Features such as volume control and echo cancellation can also be included in a softphone.

Combining a softphone and actual phones can lead to businesses having a complete calling solution.

HD Call Quality

The right telephone system should also offer HD call quality.

This is important because it allows businesses to have clear conversations with customers and clients, which can help to build trust and rapport.

A small business phone system that offers HD call quality is typically more expensive, but it’s usually worth the investment over time.

Customizable Headset

This allows businesses to provide their own headphones or earbuds, which can be a great way to save money.

In addition, it’s also worth looking for a system that offers noise-canceling capabilities, as this can be a great way to reduce distractions.

Speaking of headsets, while some companies prefer to use a corded phone to get the job done, having a cordless handset is another excellent option.

This allows businesses to move around freely while on a call, which can be a great way to increase productivity.

Multi-Line Phone Systems – FAQ

What’s A PBX System?

A PBX system is a telephone system that allows for the internal routing of calls within an organization.

A PBX can be either an on-premises system that requires the purchase and installation of hardware or a cloud-based system that uses software hosted by a third-party provider.

What’s The Difference Between Analog And Digital PBX Systems?

Analog PBX systems use traditional copper-wire phone lines to connect calls, while digital PBX systems use Internet Protocol (IP).

IP-based systems are often less expensive to maintain and provide more features than analog systems.

Can A Cordless Phone System Be Used With A PBX System?

Yes, most cordless phones are compatible with PBX systems.

However, you may need to purchase a separate base station for the cordless phone if one is not included with the PBX system.

How Does An Outage Affect A PBX System?

If there is an outage of power or Internet service, this may disrupt calls routed through a PBX system.

However, most PBX systems include backup power supplies and redundant Internet connections to minimize the risk of an outage.

Wrap Up.

A multi line phone system is an excellent tool for small businesses and bigger ones alike.

Having an office phone system that can handle multiple calls simultaneously is essential, especially as one’s business grows.

While traditional phone systems were only able to handle one call at a time, VoIP phone systems can handle multiple calls simultaneously, bringing both basic and more advanced features to those that need them.
