Migrating from traditional landlines and Public Switched Telephone Network (PSTN) to an efficient, cost-effective communication solution is a critical decision for businesses.
With choices ranging from On-Premise to Hosted PBX and Hybrid PBX, each option provides distinct advantages for each business’ requirements.
That’s why a Private Branch Exchange (PBX) can be an excellent solution for small businesses.
These systems are private telephone networks that deliver a variety of advanced features, such as extension dialing, call conferencing, call forwarding, voicemail-to-email, and customizable business hour settings.
When integrated with VoIP technology, PBX phone systems for business can process digital signals, allowing seamless call routing to any device.
Whether you’re a small business or a growing enterprise, choosing the right communication solution can boost productivity, cut expenses, and simplify operations.
In this article, we’ll guide you through the available options and help you choose the best PBX system, ensuring you make a well-informed decision that meets your specific needs.
Keep reading, but if you want to dive deeper, have a look at the webinar below, where we explain different PBX solutions and how they can match your business needs:
Choosing the best PBX business phone system for you
Before you choose the best business phone system, let’s explore each type of PBX:
- On-Premise PBX is a traditional solution, using on-site hardware, being a reliable but costly system.
- IP PBX is a VoIP-based solution that can be hosted on your own servers or private cloud, offering flexibility, advanced features, and internal control.
- Hosted PBX is a fully cloud-based phone system managed by a third party, offering scalability, ease of use, and lower upfront costs.
- Hybrid PBX combines legacy phone systems with VoIP capabilities, allowing you to use both analog and digital and IP-based phones.

When selecting a PBX phone system, it’s essential to evaluate your business’s unique needs, such as:
- Communications Budget
- Company Size
- IT Setup and Team
- Current Set up
- Features needed
- Future Needs
Now, let’s explore each of these factors:
Communications Budget
The company’s budget plays a significant role in determining the best PBX system a business can implement.
On-premises PBX systems often require a higher upfront investment in hardware and IT resources.
In contrast, cloud-based PBX systems typically operate on a subscription model, minimizing initial costs. Evaluate your budget to determine which option is better for your business.

Company Size
The size of your business will influence the type of PBX system you choose.
Companies that don’t need many phone lines, work under a remote setting and are on the smaller side of the scale might opt for cloud-based services because they offer more flexibility and are better for growth.
Bigger companies that have inside IT teams might opt for an on-premise system, since they can have full control over their business communications.
Company Size | Recommended PBX | Key Benefits |
Small Business | Cloud-Based PBX | Scalable, low maintenance |
Large Enterprise | On-Premises PBX | Greater control, customizable |
IT Setup and Team
As mentioned above, IT infrastructure and team capabilities are critical factors to consider.
On-premises PBX systems require in-house IT expertise for setup and ongoing maintenance, while cloud-based systems are managed by the provider, reducing the burden on your internal team.
If you are a reseller, you can benefit from this topic by offering tailored services to small businesses. By helping them cut costs on IT teams and simplify setup, you can provide expert support following our tutorials.
Here’s an example of how to troubleshoot incoming calls when using VoIP.ms’ services:
Current Set up
Evaluate your existing infrastructure.
Do you already have the necessary hardware, or will you need to invest in new equipment? If significant investment is required, cloud-based PBX systems may be a better fit. You’ll only need to worry about having a good internet connection.
Cloud-based solutions require minimal hardware, making them ideal for businesses looking to avoid additional expenses.
Features needed
Which features does your business require? As mentioned earlier, common PBX features include call forwarding, auto attendants, and call recording.
Advanced features like voicemail-to-email or CRM integration are offered by VoIP-enabled systems. A good service provider will allow you to create a complete communication system with every functionality you need to grow in a hassle-free manner.
If you run a mostly remote company/team pay special attention on how to integrate mobile devices to your communications set-up—upfront, this means you will need a cloud-based system instead of an on-premise one.

Future Needs
Consider scalability when making your decision.
Cloud-based PBX systems are particularly flexible, allowing you to add users or features as your business evolves. On premises PBX, while robust, can be costly and challenging to scale, especially for small businesses with growth ambitions.
H2: Common PBX features for businesses
PBX phone systems for business come equipped with a variety of features designed to enhance communication, streamline operations, and improve customer service.
Some of the most essential features that can transform the way a business handles calls and interacts with customers are:
- Call Forwarding and Routing
- Auto Attendants
- Call Recording
Call Forwarding and Routing
Efficient call routing ensures that calls reach the right person or department, improving response times and customer satisfaction. PBX can convert an incoming call to a digital signal, routing incoming calls to any device – that means, your business never misses an important call!
This feature is also invaluable when dealing with high call volume and business seasonality.
Auto Attendants
Auto attendants automatically answer all calls, providing a professional first impression by greeting callers and directing them to the appropriate extension or department.
Don’t confuse this with an IVR (Digital Receptionist) function. In this case, the automations and interactions with customers are more advanced. Think of it like this: an auto attendant is like a virtual receptionist, while an IVR mimics a customer support professional.
Call Recording
A must-have for call centers. Call recording helps businesses with key information by recording phone calls from customers, which then can be useful for training staff, compliance, and quality assurance.

It also improves customer service by enabling the review of interactions, identification of improvement areas, and development of strategies, service plans, and products tailored to customer needs.
If you want to go a step further here, you can always implement Call Transcription features, that turns calls into text you can then use for documentation and easy storage.
