What is an On-Premise Phone Systems

What is an On-Premise Phone Systems?

An on-premise telephone system often referred to as a Private Branch Exchange (PBX) is a type of telecommunications which includes all the infrastructure and hardware needed to manage calls and routing communications is situated within the physical premises of a company or other organization. It’s a traditional telephone system that has the equipment needed for receiving and making calls, including switches, servers and telephone lines that are maintained and installed on site.

If you have an on-premise phone system the company has total control over and ownership of its telephone infrastructure. This means that the company is accountable for buying and installing, configuring, and maintaining all of the required devices and programs. The system can be customized by businesses in accordance with their particular requirements by enabling features like voicemail, call routing and conferencing that are tailored to their specific requirements.

The primary distinction of an on-premise telephone device is the fact that it functions independent of internet connections in internal communications. This ensures constant service even in interruptions, which makes it a viable option for companies that value the availability of their network and its continuity.

However, phone systems that are on premises generally require a substantial initial expenditure in equipment software licenses, as well as installation cost. In addition, companies are responsible for the burden of maintaining updates, upgrades, and other maintenance that may require the use of IT specialists.

Despite all these factors the on-premise phone system is an option for a lot of companies, particularly those that have particular compliance requirements, stringent security requirements or a preference for having direct control over their telecoms infrastructure.

What is a Cloud Phone Systems?

A cloud-based telephone system also referred in the form of Hosted phone system, also known as a hosted PBX (Private Branch Exchange) or VoIP (Voice over Internet Protocol) phone system is a solution for telecommunications with the infrastructure and equipment to manage communications and calls are stored and managed off-site by a third party service provider. Contrary to traditional phone systems on premises which depend on the physical equipment that is installed in an office or commercial enterprise the cloud phone system works via the internet, using cloud-based technology to provide voice communications services.

In a cloud-based phone service, every one of functions traditionally offered by traditional on-premise PBX hardware, including call routing as well as voicemail, conferencing and auto-attendant functions are made available via the internet. Users are able to access these features using software or web interfaces typically using conventional IP telephones, computer or mobile devices that connect with the Internet.

Cloud-based phone systems give businesses greater flexibility, scalability and value-for-money when compared with traditional on-premise options. They are especially suited to companies with distributed or remote workforces, and businesses that want to cut down on upfront costs for telecommunications infrastructure, while increasing the flexibility and access.

What is the difference between cloud and on-premise phone system?

The main difference between on-premise and cloud telephone systems lies in the manner they are managed, deployed and accessed:


  • On-Premise: In an on-premise telephone system, all of the hardware and infrastructure needed for the telephone system, including switches, servers and telephone lines are installed and maintained on your premises. Company.

  • Cloud: Cloud in a cloud-based phone system the hardware and infrastructure to run the system is stored and managed off-site by a third-party service company. The system is operated over the internet, and utilizes cloud-based technology to offer voice communication services.

Ownership and Control:

  • On-Premise: By having an on-premise system, the company is in complete control and ownership over its phone system. This includes buying as well as configuring and maintaining all of the required equipment and components.

  • Cloud: Cloud in a cloud system the service provider is the owner and runs the infrastructure, including software, hardware, as well as network elements. Companies access the cloud system via websites or applications that run software.


  • On-Premise: On-premise systems function independently of internet connections in order to handle internal communications, offering reliable communication services, even in internet downtimes. They are thought to be more secure in this regard.

  • Cloud: Cloud-based systems depend on the internet to provide all communication. Although this may be a problem in areas with weak internet access, improvements in the infrastructure of the internet have drastically enhanced the reliability and performance of VoIP services.


  • On-Premise: On-Premise systems require an initial expenditure in software, hardware licenses, and installation expenses. In addition, regular maintenance, upgrades, and updates require additional costs and the use of IT specialists.

  • Cloud: Cloud solutions generally have lower initial costs than on-premise solutions because businesses don't have to spend money on purchasing or maintaining hardware. Instead they pay a monthly cost based on the use.

The major distinctions between cloud and on-premise phone systems are in the deployment method, the ownership and control aspect, elements of reliability, and cost structures. Companies must take into consideration their individual requirements, preferences, as well as resources when deciding between these two solutions for telecommunications.

Cloud based phone system vs on-premise phone system: Which is right for your business?

The choice between a cloud-based telephone system and a traditional on-premise option will depend on many aspects, such as your company’s requirements and budget, scalability demands as well as IT capabilities. This comparison will aid you in determining which is best for your business:

Cloud-Based Phone System


  1. Scalability:  Cloud systems are adaptable and allow you to add or remove features and users as your company grows or alters.

  2. Flexibility: Users are able to connect to the system from any location via an internet connection, making it possible to work remotely and move around.

  3. Cost-Effectiveness: Lower initial expenses since there’s no need to purchase or maintain hardware. Instead you pay a subscription fee based upon use.

  4. Automatic Updates: These service providers are responsible for maintenance and system updates to ensure that the system is up-to date with the most recent technology and patches for security.

  5. Reliability:  Despite the fact that VoIP relies on the internet, advances have increased the reliability and quality of the VoIP service.


  1. Internet Dependence: Cloud systems require an internet connection that is reliable for all communications. This is a challenge in areas that have poor internet connectivity.

  2. Data Security: The security of data is kept off-site, which raises questions about security of data and privacy. However, reliable service providers have implemented strong security measures.

On-Premise Phone System


  1. Ownership and Control: Full control and ownership over the telephony infrastructure, which allows for security and customization specifically tailored to your requirements.

  2. Reliability: Works independent of Internet connections to make internal phone calls ensuring constant communication even during interruptions in internet connectivity.

  3. Long-Term Cost Efficiency: In spite of the higher initial costs, overall costs over time could be lower because of the absence of subscription charges.

  4. Data Security: The data is saved on site, which gives businesses full control and oversight of security measures.


  1. High Upfront Costs: A large expenditure in software, hardware licenses and installation fees.

  2. Scalability Challenges: Expansion of the system could require additional hardware, as well as complicated modifications to the configuration.

  3. Maintenance Responsibility: Companies are responsible for maintaining their IT infrastructure, updating and upgrades. This requires special IT staff.

Choosing the Right Option: Cloud based phone system vs on-premise phone system

The decision between a cloud-based telephone system or an on-premise system is essential for any company. Let’s examine the factors that affect the decision and help you choose the best option that is tailored to your company’s requirements and goals.
