In the evolving world of business phone systems, a cloud-based private branch exchange (PBX) is a modern way for companies to communicate and route calls via the internet. Cloud PBX systems often replace costly on-premises PBX hardware that uses traditional telephone equipment and phone service providers to handle voice communications.
Cloud PBX is often used interchangeably with hosted PBX because a third party manages the equipment; however, there are significant differences. Cloud-based phone systems are typically implemented for their cost-savings potential and advanced calling features, including auto-attendants, call routing, mobile device support, voicemail to email, free local numbers, call recording and post-call notes.
If you’re considering a cloud PBX for your business, here’s what you need to know.
How does cloud PBX work?
Unlike a traditional telephone system, which uses copper landlines to transmit voice data, cloud PBX uses your business broadband connection to make communication possible. With cloud or hosted systems, voice data from your device is transformed into encrypted data packets that are sent through your internet service provider’s network to establish a connection and maintain the call.
Your service provider owns and manages all major equipment in a cloud PBX system. You are responsible for providing an internet-connected device or IP phone to connect to the internet.

Cloud PBX vs. on-premises PBX
For business owners, one of the most significant differences between cloud PBX and on-premises PBX is the hardware’s location. On-premises PBX systems require onsite hardware and IT maintenance that comes at the business’s expense. However, there are several other notable differences between these two phone systems to consider.
|Cloud PBX||On-premises PBX|
|Data is stored and managed in the cloud with no onsite hardware required.||You own and manage your onsite telecom hardware and data.|
|You can use IP phones and internet-connected devices to make and receive calls anywhere.||You use traditional desk phones to make and receive calls from a fixed location.|
|It integrates with popular business software and tools for unified communications.||It integrates with older analog devices for paging or facility access control.|
|It’s perfectly suited for companies with remote teams.||It’s designed for in-office use only.|
|There are minimal to no upfront or maintenance costs.||There are significant upfront and maintenance costs.|
|There are monthly subscription fees in perpetuity for each user.||There’s the potential for lower monthly long-term costs as a result of owning your equipment.|
Virtual PBX vs. cloud PBX
Virtual and cloud PBX systems are similar in that neither needs the onsite hardware that on-premises systems require. A virtual PBX is implemented to route incoming calls using interactive voice response (IVR) or auto-attendants.
This widely used technology lets callers interact with prerecorded messages through their dial pad to choose where the call should be routed. For example, if you’re calling your internet service provider, you might choose from options such as billing and technical support. This feature is also available with cloud PBX systems.
Virtual PBX systems are typically used at small businesses that don’t spend much time on the phone and don’t want to pay for a complete business phone system. Cloud PBX solutions can be found in companies of all sizes and industries where telephone communications and video conferencing are essential for conducting business.
Pros and cons of cloud PBX
The benefits and cost-saving potential of cloud PBX generally outweigh its disadvantages. However, cloud PBX phone systems are not perfect for every business in every location.
- It has low upfront costs.
- There’s no equipment to maintain.
- It provides flexibility for remote workers.
- It has a wide range of useful features and tools.
- It typically includes voice, video, chat and SMS communications.
- It integrates with other popular business applications, including CRM software.
- Your call quality is only as good as your internet connection.
- Your employees may need training on advanced features.
- Network routers may need fine-tuning to support cloud telephony.
- You’ll need an annual or monthly service plan that’s most likely priced per user.
What to look for in a cloud PBX provider
Most cloud PBX providers offer similar monthly and annual pricing structures, advertised uptimes that exceed 99.9%, and a wide range of integrations that can incorporate your new phone system into other software applications and tools your company uses daily.
With so much similarity between providers, shoppers should focus on the features they would utilize the most with a cloud-based phone system and make sure the move to cloud PBX doesn’t negatively impact the way their employees work.
Here are some important factors to consider:
- Integrations: Integrations are a great place to start when you’re exploring cloud-based phone system providers. Most businesses are locked into several popular software applications, making it worthwhile to focus your search on the cloud PBX providers that will fit seamlessly into your existing toolset. Otherwise, your seemingly cost-effective phone solution may lead to additional expenses if you need to migrate to a different CRM system, for example.
- Price: Price is the second area to examine. Large companies should take the time to call a few cloud-based phone service providers to inquire about discounted pricing with an enterprise plan. Generally speaking, you’ll be able to find a lower rate by committing to an annual service plan instead of a recurring monthly payment. It’s worth noting that fees are typically charged per user.
- Flexibility: Plan flexibility is another essential aspect to consider. Not everyone in your business likely needs the same features in a phone system. Many businesses that are building a sales team or using remote customer service agents may need higher-priced advanced calling features. On the other hand, in-office support staff may need only the most basic, entry-level calling features.
- Support: Customer support can be critical, depending on your team’s experience with cloud-based software. Many cloud PBX providers offer 24/7 support with every subscription plan; however, some companies may limit support hours with their lower-cost and entry-level plans.
- Hardware: Hardware such as IP desk phones, conference phones, and headsets may not be necessary for all cloud PBX users, but if you’re going to purchase a significant number of devices, you may be able to find a better deal through your phone service provider. Companies such as Nextiva offer dozens of hardware options with discounted pricing available.

Cloud PBX FAQs
How much does a cloud PBX system cost?
Cloud PBX systems typically cost $20 to $60 per monthly user, depending on the features and services. Many hosted PBX providers offer discounts based on the number of users as well as contract length.
Because these phone systems run on most internet-connected devices, there’s often no need to purchase anything other than inexpensive headsets to take calls. However, companies that prefer traditional telephones can purchase IP phones that look and function like desk phones, but they’re connected via Ethernet cable instead of a phone line.
Is cloud PBX a VoIP?
Cloud PBX systems use Voice over Internet Protocol (VoIP) technology to make voice, chat and video communication possible. The terms “cloud” and “hosted” simply let consumers know that the service provider owns and maintains all the hardware required to transfer digital data packets containing communications between callers.
What are the benefits of a cloud PBX system?
A cloud PBX system is an affordable way to provide advanced telephone features to in-office and remote employees. It can improve communication across an organization and track interactions to improve customer experiences. It can also help increase performance with real-time call analysis, post-call summaries, and detailed caller identification to help provide personalized and professional service over the phone.
