Top 10 Sideline Alternatives

Introduction

If you’ve been hearing more about VoIP lately, it’s because it’s quickly becoming the go-to choice for modern business communication. Instead of relying on landlines or mobile networks, VoIP lets you make calls over the internet. It’s flexible, cost-effective, and works across devices, making it a great fit for remote teams, freelancers, and growing businesses alike.

That’s exactly why many users assume apps like Sideline fall into the VoIP category, but they don’t. Sideline isn’t actually a VoIP service; it runs on your mobile carrier’s network, not the internet. This means you’re still tied to your phone plan, and you miss out on key VoIP advantages like advanced call routing, shared team numbers, and multi-device syncing.

If you’re looking for a smarter, more scalable way to handle business calls and messages, a true VoIP solution is the better fit. That’s why more and more professionals are turning to Sideline alternatives, platforms that offer more features, better flexibility, and a smoother communication experience overall.

What is Sideline?

Sideline is a mobile app that gives users a second phone number on their existing device. It’s designed for professionals, freelancers, and small business owners who want to keep their personal and business calls separate. The app offers basic calling and texting features over the carrier network (not VoIP), making it simple but limited compared to more advanced Sideline alternatives.

Sideline Features

• Second Phone Number: Add a separate business number to your personal phone, so you can keep work and personal calls completely separate.
• Text Messaging (SMS & MMS): Easily send and receive texts, photos, and videos using your business number, just like you would with your regular phone.
• Group Messaging: Have conversations with multiple clients or teammates in one thread, making it easier to coordinate and respond.
• Auto-Reply:  Set automatic replies for when you’re busy, driving, or unavailable, so customers still get a response even if you can’t reply right away.
• Team Number: Share one business number with your entire team, so anyone can pick up texts or calls without missing a beat.
• Voicemail & Custom Greetings: Create professional voicemail messages and easily manage missed calls when you’re not around.
• Caller ID: Always know if an incoming call is for business or personal, Sideline clearly shows which number it’s coming through.
• Business Hours: Set working hours so calls and texts outside of those times automatically go to voicemail, helping you maintain boundaries.
• Call Forwarding: Forward calls to another number when you’re unavailable or want someone else to handle them.
• Number Porting: Keep your current business number by transferring it to Sideline, or take it with you if you leave the service.
• Web Messaging: Use your computer to send and receive texts, so you can stay connected even when you’re not on your phone.
• Contact Management: Keeps track of recent conversations and customer info.

Sideline Pros

• Simple and Professional: Lets you separate business from personal life without needing an extra device.

• Texting Features Are Robust: Includes group texts, auto-replies, and business hour tools.
• Affordable for Solo Use: Great option for individual professionals, freelancers, or small business owners.
• Team Number Option: Makes it easy for teams to share communication responsibilities using one line.

Sideline Cons

• Not a Full Business Phone System: Lacks advanced features like IVR, call routing, in-depth call analytics, API or CRM integrations.
• No VoIP Calling by Default: Since it uses your carrier network, it doesn’t work well without cell service (unless you upgrade to Sideline Pro VoIP).
• Limited Analytics: Doesn’t offer in-depth reporting or analytics for call tracking.
• Not Ideal for Large Teams: Best suited for individuals or very small teams; not scalable for complex call workflows.

Why do Businesses Seek Sideline alternatives?

Looking for a Sideline alternative? You’re not alone, many users are switching to other apps like Sideline because of cost, features, and ease of use. Some of the major ones are: 

Not the Most Budget-Friendly Option for Small Teams

Sideline can get pricey, especially if you’re a solo user or running a small team. There are many free Sideline number options or low-cost Sideline competitors out there that do the same job, sometimes even better, without hurting your wallet.

Limited Customization to Fit Unique Practice Needs

If you need your app to fit your exact way of working, Sideline might feel a bit rigid. Many users want apps like Sideline that let them tweak features, change settings, or organize things the way they like. Unfortunately, Sideline app doesn’t offer much flexibility.

Scalability May Be a Challenge for Growing Clinics

As your team or business grows, you need tools that grow with you. But Sideline app can feel too basic when you need multiple numbers, advanced call routing, or shared inboxes. That’s when many users look for a more scalable Sideline app alternative.

Lacks a Few Key Functional Features

There are things you might expect, like voicemail transcription, better contact tagging, or a cleaner desktop setup, but Sideline app sometimes misses the mark. Other Sideline alternatives offer more features out of the box.

Third-Party Integrations Can Be Complicated

If you want to connect Sideline with tools like your CRM or team chat apps, it’s not always smooth. Many people switch to Sideline alternatives that play nicer with tools they already use.

Needs Improvement in Overall Ease of Use

At the end of the day, people just want something that works, fast and without frustration. And that’s why so many users are searching for a Sideline app alternative that feels simpler, faster, and more enjoyable to use.

What to look for in a Sideline alternative?

Here are must have features every VoIP software should have: 

AI Capabilities

A good Sideline alternative should include smart AI tools like voicemail transcription, call summaries, and auto-replies. These features help teams save time, stay organized, and reduce manual work during busy hours.

Click-to-Call Functionality

Click-to-call means you can dial straight from your browser, CRM, or email without typing the number. It speeds things up and avoids dialing mistakes, making it essential in most Sideline app alternatives.

Call Routing & IVR

With call routing and IVR, incoming calls automatically go to the right person or department. It creates a smoother caller experience and helps your team stay efficient, even during high call volume.

Custom Caller ID

Custom caller ID lets you decide what number shows when you make a call, your main business line, a tracking number, or something else. It keeps your communication professional and consistent.

Mobile App Support

You shouldn’t have to sit at a desk to manage your calls. The best Sideline alternatives come with full-featured mobile apps so you can take calls, respond to texts, and check voicemail on the go.

Call Transfer

Call transfer lets you talk to a teammate before sending the caller through, so handoffs feel smooth and personal. It’s a key feature for teams handling support or sales in any Sideline number app.

Team Collaboration Tools

Look for tools that let teams share call history, notes, or even inboxes. These features make Sideline competitors much more team-friendly, especially for growing businesses or remote staff.

HIPAA or GDPR Compliance

If your business handles sensitive or private info, you’ll need a Sideline alternative that follows data privacy laws. Apps with HIPAA or GDPR compliance help protect your business and your customers.

VoIP Call Quality & Reliability

Good call quality really matters, especially if your team works remotely or takes a lot of calls. A solid Sideline alternative should give you clear sound without constant dropouts or connection issues.

Voicemail Transcription

Instead of listening to every voicemail, transcription lets you read messages like emails. It saves time and helps you catch important info without stopping to play recordings.

Call Queuing

When lines are busy, call queuing keeps callers in order instead of sending them to voicemail. It helps teams manage volume better and improves customer satisfaction.

Call Recording

Recording calls is useful for training, reviews, or compliance. A good Sideline alternative lets you record easily, store safely, and replay when needed.

Number Porting

You shouldn’t have to give up your business number when switching platforms. Many Sideline app alternatives allow easy number porting with zero downtime.

Integration with CRMs

Connecting your calling tool to CRMs like HubSpot or Salesforce helps log calls, view customer details, and manage follow-ups in one place. It streamlines sales and support workflows.

Real-Time Call Monitoring

Supervisors can monitor live calls to give real-time feedback, help guide tricky conversations, or jump in when necessary. This not only helps reps improve on the spot but also ensures customers get the best experience possible. 

Auto Dialer / Power Dialer

Auto and power dialers can call through a list of numbers for you, so your team doesn’t have to waste time dialing each one by hand. They’re a great tool for sales or support teams using apps like Sideline to work faster and reach more people.

Analytics & Call Reporting

Call analytics gives you a clear view of what’s going well and where things can improve. A good Sideline alternative should offer simple, visual reports that track things like call volume, call length, and how your team is performing.

Multi-Device Sync

You can start a call on your computer and switch to your phone without missing a word. Multi-device sync keeps your communication flowing smoothly, so you stay connected no matter which device you’re using.

Cloudtalk Reviews

“The phone application needs more work. Doesn’t seem to “ring” unless the app is open. Would love to have more mobility since working remote.”

“The customer service was sometimes slow to respond or did not have answers for my questions. We have encountered some bugs with the service but they have not been critical and were fixed very quickly after giving information.”
