How does OpenPhone’s multi-line phone system work?

OpenPhone is powered by Voice over Internet Protocol (VoIP) technology. That way, you can access your business number from any computer, smartphone, or tablet using the internet. In the past, businesses needed custom desk phones, headsets, and hardware to connect multiple lines to their phones. Unlike traditional office phones, VoIP phone systems make it easy to set up and use multiple numbers simultaneously, because virtual numbers aren’t tied to a physical device or a single location. 

Teams can easily add multiple business phone numbers to their OpenPhone workspace and choose their preferred number. Each number has a dedicated inbox where team members can make calls, send messages, and view a record of all customer communications from that number. It’s easy to share numbers across members of a team, service area, or department. With shared numbers, your team can be even on separate calls using the same number at the same time.

Whether you need to provide customer support, make sales, or fulfill service requests, OpenPhone’s small business phone system is designed to help you communicate with your customers with ease, at any call volume.

What is a multi-line phone system?
down arrow

Multiple-line phone systems are business phones that have multiple phone numbers on one single phone. Traditionally, having multiple phone numbers on one phone was difficult and required custom, expensive equipment, like a desk phone or handset, to achieve.

Now, with virtual phone systems, it’s easy to add multiple numbers to your business phone and manage them in one place. You can also select the types of numbers your team uses, like local or toll-free numbers. Then your team can call and text from a smartphone, computer, or tablet. 

What is the best multi-line phone system for small businesses?
down arrow

Plus, go deeper with understanding your call trends with call views, AI call tags, and call and text analytics. 

What are the benefits of multiple phone lines for businesses?
down arrow

Operating your business with one phone number can make it difficult to handle  high call volumes. Multiple phone lines set your business up to grow and provide a great customer experience.

With multiple phone lines, your team can make and receive calls and texts simultaneously, ensuring your customers can always connect with you.

Local numbers allow you operate in multiple regions to build trust with customers. Toll-free numbers give you the ability to offer nationwide customer support. When you have both numbers side by side, you can easily build relationships with customers across multiple regions.

Can a cloud-based phone system do the same thing that a landline can?
down arrow

A cloud-based phone system  is a modern alternative to a landline. It has many more features, and it is also more cost-effective and easier to use.

Choosing a cloud phone system over a corded or cordless phone one allows you to take advantage of several advanced features. For example, you can share calling and texting across your entire team with shared numbers and customize call routing during and after your business hours. Also, easily keep track of your customer information with contact personalization, and third-party integrations. Plus, you can take advantage of AI features like call summaries as well.

Comparing cloud phones and landlines is a bit like comparing horses and cars. They both get you where you need to go — one option is just the modern way of doing it. 

Is a virtual multi-line phone system more expensive?
down arrow

Multi-line phone systems, also known as VoIP services, are much more affordable than traditional phone systems that use private branch exchange (PBX system) hardware.

You don’t need any custom equipment to get started with virtual multi-line phone systems. You simply start using them with your existing softphones and computers. Your team can access both shared numbers and their own number from anywhere with an Internet connection with a virtual system.

How do I use my existing phone number with my small business phone system?

If you already have a business number you want to keep, you can port your existing number to OpenPhone.

Porting a number in OpenPhone is straightforward and takes between 1-2 weeks, depending on your current service provider. Learn more about porting a number to OpenPhone.

down arrow
