What is a multi-line phone system and how does it work

If your business has a large volume of incoming and outgoing calls, or you’re quickly reaching that point, you need a multi-line phone system. A multi-line phone system maximizes communication, and improves productivity and efficiency so you can quickly and easily transfer calls and communicate internally with employees and externally with customers.

What is a multi-line phone system?

A multi-line phone system lets you handle two or more calls simultaneously. It enables employees to place calls on hold, dial internal or external numbers, and return to the line. Multi-line phone systems differ from traditional phone systems because they enable multiple parties to be on the phone at one time – traditional phones, on the other hand, are designed to only send audio data between two parties at once.

There are two main types of multi-line phone systems, traditional analog systems and modern digital systems.

Analog Multi-Line Phone Systems

The first is where a single landline provides two-line functionality using existing wires. You’d wire these into phone jacks by using yellow and black wires. You’ll need to pay for an extra line from the phone company to use it. Analog handsets can switch lines and place calls on hold using the flash button.

The other type is a traditional PBX system, which is a private branch exchange. A traditional PBX system uses a physical control unit to manage the phone lines. This system requires special wiring and equipment, and it can be difficult to expand if you need to add more phone lines in the future. Additionally, Analog Multi-line PBX systems are more expensive to maintain than VoIP systems. This is why digital systems in most modern businesses are replacing traditional phone systems.

VoIP Multi-Line Phone Systems

A more modern and efficient option is based on VoIP (Voice over Internet Protocol) technology. VoIP stands for Voice Over Internet Protocol and refers to how data packets are delivered through the internet rather than traditional landlines like those used by analog phones. These systems use your existing internet connection to make and receive calls. This eliminates the need for physical phone lines, which can save you a significant amount of money on your monthly phone bill. A VoIP multi-line phone system is also easier to scale than an analog system so that it can grow with your business.

Types of Multi-Line Phone Systems

2-line phones: A 2-line phone system is the most basic type of multi-line system and is typically used by solopreneurs, small businesses, or home offices. These systems have two lines that can be used simultaneously so that you can take two calls at the same time.

4-line phones: A 4-line phone system is a good option for small businesses that need a little more than a 2-line system. With four lines, you can take four calls at the same time, which is perfect for businesses with a moderate amount of call volume.

5+ line phones: If you have a high volume of calls coming into your business, then you’ll need a multi-line phone system with five lines or more.

Features to look for in a multi-line phone system

Below is a brief explanation of the common features, but consider your current needs and what features will streamline communication and maximize productivity for your staff.

Caller ID

Caller ID lets you see who is calling. You can choose from two options: caller ID, which displays the phone number of the caller; or caller ID with name, which displays the phone number and the name of the caller. This feature can help identify which calls are important and which ones are spam.

Speakerphone

Speakerphone can be helpful if you need to be hands-free while you’re on a call, or, say if you’re in the middle of a meeting and need to conference in someone.

Voicemail

Voicemail allows a caller to leave a recorded message for someone who is unable to answer the phone. When the called party does not answer their phone, the call is forwarded to their voicemail box, where the caller can leave a message. The called party can then listen to the message at their convenience.

Auto attendant

The auto attendant greets callers and provides them with a directory of extensions.

Hold

Call hold lets you pause a call so you can talk with a colleague or answer another call.

Conference Calling

With conference calling, three or more people can participate in a phone call simultaneously. Conference calling is a great way to stay in touch with co-workers, clients, and others who are important to your business. It allows multiple people to participate in a call, and each person can contribute to the discussion. Conference calls are a convenient way to connect with people in different locations.

Call Recording

Call recording logs telephone conversations in a digital audio file format. Call recordings can be useful for businesses in a number of ways, for instance, for quality control and training purposes. Call recording differs from call reporting, which keeps track of specific data but not the conversation.

Benefits of a multi-line phone system

Lower costs

Costs are generally low unless you need to purchase all new equipment for several employees. Many multi-line systems are moving to internet-based models, which hosts all data in the cloud and sends call information over the internet, which keeps costs lower than if you use traditional physical phone lines.

Flexibility

Multi-line phone systems are flexible and easy to scale – they grow as your business expands. Many of these systems let you easily add (depending on your configuration) extra handsets using cables, wired or wireless adapters, or expansion kits that are easy to install.

Reliable and secure

Multi-line systems are highly reliable and secure. Many encrypt your data, and in case of a power outage, a battery continues to ensure customers can reach you. Additionally, if you are using landlines, these are still some of the most stable methods of communication in existence.

Convenience

A multi-line phone system simplifies life for you and your employees. They become more productive and can propel the company forward.

Reliability

Your phone system needs to be reliable and secure. On-premises phone systems leave you vulnerable to power or network outages.
VoIP phone systems rely on multiple data centers for redundancy. Your business works uninterrupted, no matter what happens to the phone infrastructure.

Conclusion

Multi-line phone systems are a great way to improve your business communication. By centralizing all of your calls through one system, you can ensure that everyone is on the same page and that no important calls are missed. These systems are also easy to install and maintain, making them an excellent option for businesses of all sizes.

If you’re thinking about upgrading your business phone system, a VoIP multi-line phone system is definitely worth considering. With its many benefits, it’s sure to help improve you business.
