Formerly known as Junction Networks, OnSIP claims to provide services to over 100,000 businesses. But is it really the right fit for yours?

When choosing business VoIP systems, OnSIP often comes across as an affordable and flexible solution for small businesses. However, its highly add-on-based model can quickly drive up costs and leave your business stuck with limited functionality.

In this detailed pricing analysis, we’ll break down OnSIP VoIP pricing, features, and costs to give business leaders a clear understanding of what to expect before making an investment. Keep reading to find out!

Key Takeaways


• With integrations limited to HubSpot and Zendesk, restricted international coverage, and a lack of advanced calling features, OnSIP is best suited for businesses with very basic communication needs.
  
• OnSIP pricing tiers are divided into Unlimited ($18.95 per user/month), and Basic ($49.95 per account/month), with many add-ons available.
  
• Although marketed as a flexible, pay-for-what-you-need approach, many of OnSIP’s add-ons include features that are fundamental for the effective operation of a phone system, making the overall cost much higher than expected.

Overview of OnSIP Pricing & Plans

OnSIP combines a business VoIP system with virtual business communication tools, offering a calling and video solution tailored for small companies.

OnSIP breaks away from the standard monthly per-user pricing used by competitors. While its Unlimited plan sticks to that structure, the Basic plan takes a different approach by pricing based on the number of accounts.

The Unlimited plan starts at $18.95 per user/month, and the Basic plan starts at $49.95 per account/month. Take a better look at what they offer:

Basic Plan

The OnSIP Basic plan, priced at $49.95 per account/month, is an entry-level business phone service designed for small teams and organizations seeking a simple communication solution. This plan has no user minimum and includes a very limited features set.

Key Features:

• Announcements 
• Auto attendants – Interactive Voice Response (IVR)
• Voicemail + VM-to-email
• Ring Groups

Missing from this tier:

• Calling minutes
• Call Parking
• Busy Lamp Field (BLF)

Unlimited Plan

OnSIP’s Unlimited plan costs $18.95 per user per month, with a minimum of 5 users. It gives you unlimited calling within OnSIP’s standard area network and a better–but still limited–mix of calling features.

The virtual phone system includes unlimited usage of routing, voicemail, and collaboration features, plus free desk phones or headsets.

Key Features:

• Unlimited usage of basic call-managing features

Free Plan

The OnSIP Free Plan is a web-based solution for internal communication. It supports calls only between SIP (Session Initiation Protocol) phones, meaning it cannot be used to call regular phone numbers.

This plan includes up to 100 users, unlimited extensions, and unlimited web voice and video calling. To connect, callers need to use their SIP addresses.

Key Features:

• Up to 100 users 
• Free SIP to SIP calling
• Zendesk and HubSpot basic integrations

OnSIP’s Add-Ons

OnSIP offers a large number of features as add-ons that can catch your eye. However, this approach can be misleading for someone looking for an affordable solution. 

While the standard plans look accessible, their limited features often mean you’ll need to buy several add-ons to get what you actually need—making the overall OnSIP cost much higher than expected.

Unpacking OnSIP’s Limitations and Hidden Costs

While OnSIP claims to offer flexible pricing, there are notable limitations that may impact its suitability for some businesses. Below, we break down the key drawbacks into specific areas:

Limited International Coverage 

For businesses with a global footprint, OnSIP’s international calling capabilities fall behind competitors.

The Unlimited plan’s minutes and the Basic plan’s 3.2 cents per minute rate are restricted to OnSIP’s standard calling area, which is limited to major cities in 21 countries. This coverage only applies to landline numbers, and any calls outside this area are subject to additional international charges. 

Restricted Integrations

On average, businesses use 80 SaaS applications in their tech stack to streamline operations, automate workflows, and optimize customer interactions. Here, OnSIP also underdelivers, offering integrations with only two platforms: HubSpot and Zendesk.

For businesses requiring compatibility with other essential tools like Salesforce, Pipedrive, Zapier, or Zoho, this limited integration capability can lead to workflow disruptions and unnecessary challenges.

Essential Features Locked Behind Add-Ons

One of the most significant limitations of OnSIP is the restricted set of features included in its core plans. Unlike competitors like CloudTalk, which bundle advanced capabilities into their standard offerings, OnSIP provides only the basics.

Key tools such as Intelligent Call Routing, Analytics, and Call Monitoring are classified as paid add-ons. This means businesses requiring these essential features must pay extra, making OnSIP less competitive in terms of value for money.

On top of that, features like Power Dialer, Voicemail Drop, SMS & MMS, and Workflow Automation are completely out of OnSIP’s offerings.

CloudTalk vs. OnSIP: Side-by-Side Comparison

Choosing between OnSIP and CloudTalk? Here’s a direct comparison of both platforms in terms of cost, flexibility, and features.

CloudTalk Vs. OnSIP: Key Takeaways

To make things easier for you, we’ve laid out the key factors so you can confidently choose the solution that’s right for you.

Feature-to-Price Ratio

CloudTalk offers a robust set of advanced tools, such as Power Dialer, Smart Dialer, Call Flow Designer (CFD), and Automatic Call Distribution (ACD), in its standard packages.

These features streamline inbound and outbound calling processes, boosting efficiency and enhancing the performance of sales and support teams.

In comparison, OnSIP’s features are more basic and often require additional add-ons. This reliance on paid upgrades can drive up costs while still lacking the depth and efficiency provided by CloudTalk’s packages. 

International Coverage

CloudTalk’s impressive international reach makes global operations seem local. It offers virtual phone numbers in over 180 countries, allowing businesses to establish a local presence in multiple markets and connect with customers and remote teams worldwide. 

OnSIP struggles to meet the needs of companies with international ambitions. Its coverage is significantly more restricted, limited to its standard area network of just 21 countries, making it less suitable for organizations with operations spread across different countries.

Third-Party Integrations

As mentioned, OnSIP only integrates with HubSpot and Zendesk. This restriction leaves businesses without access to other popular essential third-party platforms, which are crucial for streamlining workflows and managing customer relationships.

CloudTalk goes in the opposite direction, providing integration with 40 industry-leading solutions (HubSpot, Salesforce, Zapier, and more), ensuring your operation is fully connected.

OnSIP’s Best Features

OnSIP has its own strengths as well. Here are a few key factors worth considering:

• sayso Website Chat: It’s a button you can embed into your website and lets visitors connect instantly with a live rep via voice or video by selecting customized options. Agents receive the call as if it were a normal inbound call.
  
• Large Unlimited Calling Network: Unlike many VoIP providers that limit domestic calling to the US and Canada, OnSIP extends its unlimited calling network to 21 countries, specifically for landline numbers. This can be highly valuable for businesses that don’t depend heavily on mobile devices.
  
• Video Conference Capability: OnSIP includes basic video conferencing tools through its platform, allowing users to host face-to-face meetings via their web browser without the need for additional software or downloads.

OnSIP Pros & Cons

Cloudtalk: Connecting Your Business To The Future

OnSIP might market itself as a modern VoIP solution, but it’s better suited for businesses that primarily communicate with landline numbers. Its unlimited calling only applies to fixed-line phones, making it a decent option for predictable, controlled calling needs.

Considering that landline usage has dropped worldwide by more than 60% since 2005, the benefit of unlimited calls to these numbers has drastically lost value. This has made one of the best benefits of OnSIP increasingly restricted and doomed to disappear.

For businesses looking for flexibility while accessing advanced integrations and features, look no further than CloudTalk. It’s the ideal alternative for businesses seeking a truly flexible and future-ready VoIP platform.
