Types of Business phone systems
Generally speaking, there are two basic types of office phone systems: On Premise PBX (private branch exchange) Phone System, and Cloud VoIP phone system.
What is on-premises?
Software that is "on-premises" means that the servers are on-site. Software hosted on-site by organizations has a dedicated room for data hardware managed and maintained by employees.
What is private branch exchange (PBX)?
Private branch exchanges (PBX) are telephone systems that switch calls between users using local lines and provide users with a limited number of outside phone lines. So, this allows organizations to save money rather than purchasing an external phone line for each user.
What is on-premises PBX?
The term "on-premises" refers to a PBX system being hosted at the company's premises. With on-premises PBX, you can enjoy IP routing technology, which sends phone calls by IP packets over the internet instead of using circuits. VoIP communication is also possible with on-premises PBX.
What is cloud phone system?
Cloud-based phone services use the internet to send voice signals between different IP addresses. It does away with the need for hardware on-premise, reducing the maintenance costs of traditional telephone lines.
Cloud phone systems are usually called something different, such as:
- Hosted phone systems
- VoIP phone systems
- IP phone systems
How cloud phone system works?
- Voice signals can be transformed into small bits of data transmitted through voice pockets.
- Voice packets are sent over the internet to the VoIP provider of the sender.
- The VoIP provider routes the call through a cloud-based Private Branch Exchange.
- When the pocket reaches the VoIP receiver, it converts back to voice signals.

What is the difference between cloud Phone System and PBX phone systems?
Although they are similar in specific ways, cloud and on-premise phone systems have apparent differences. Many people believe that the cloud phone system doesn't work in their office and, therefore, it is slow and lacks features; this is untrue.
A cloud phone system can be as fast, if not faster, than an on-premise system due to its stable broadband speed. On-premise systems are not as feature-rich as cloud phone systems.
Cloud Phone System | On Premise PBX Phone System |
---|---|
Modern technology | Old technology |
Low cost per user | Expensive to buy |
Along with mobile app | No mobile app |
Easy plug and use | Long installation process |
Life time free upgrades | Need maintenance |
Free headset | Expensive hardware’s |
Cloud line (SIP) | Physical line (ISDN) |
Packet data switch | Circuit data switch |
