Sideline Alternatives: Top 10 Alternatives and Competitors

With the emergence of COVID-19 and deeper penetration of the internet, remote work culture gained prominence to define the new normal eventually. It’s important for businesses to keep their teams in the loop, no matter where and how they work. 

How you communicate with your team and customers is a key determinant of your business identity. A second or separate phone number from the same phone can help you draw a line between your professional communications and personal lives. 

In your search for a fruitful solution, chances are that you might land up in Sideline’s second number setup. When you dive deeper, you will understand that Sideline lacks essential features. In this blog, we present an evaluation of the best Sideline alternatives that may better align with your needs and requirements. 

What Should You Know About Sideline?

Before you nod to go with Sideline as the second phone number for business, you must understand that Sideline is not a VoIP-based phone system

Sideline provides a second phone number and voicemail through the mobile application. Instead of communicating over VoIP, Sideline uses your existing phone connection. 


Some of the key features of Sideline business phone system are, 

  • Auto attendant,
  • Group messaging,
  • International calling,
  • Auto-response to calls and texts,
  • Shared number.

These features are good enough for small businesses that are just kickstarting their business operations and have only a handful of clients. But, as they eventually scale and broaden their scope, businesses find that Sideline lacks some of the essential features.

Though Sideline offers some of the important features needed for a business, there exists no plan that has all of these features in a go. Say, you cannot find a plan that offers both auto attendant and shared number. You have to trade off one for the other. 

Beyond, Sideline also lacks call recording, toll-free numbers, and other advanced call management features that come with VoIP (Voice over Internet Protocol) phones. This is highly important if you are targeting a broad customer base and they might require support and assistance from the customer service team.

Next, Sideline does not offer analytics and reporting tools like VoIP solution providers. This is more important as businesses scale and expand their client base.

When a business grows, the team naturally scales up. To simplify project management tasks, you will need an efficient phone system that lets you build communication and coordination between the team members. Sideline lacks integration tools and does not go well with many third-party applications. 

The subscription plans are quite complex and are not effective in terms of cost and utility for small businesses and startups. 

Sideline uses data from the mobile service provider to make and receive calls. Because it uses minutes from your carrier, it comes with a hidden charge, unlike VoIP and cloud phone systems that operate over the internet. 

How To Choose The Best Sideline Alternative?

Following are some of the important criteria that you must consider while you look up to find a second phone number for your business. We have used the same to evaluate and pick the top 10 Sideline alternatives.
