A PBX stands for subscriber telephone exchange and is a private telephone network used within a business. users of a PBX telephone system must share a certain number of external lines in order to make calls to the outside world.
One of the latest trends in PBX telephone systems is the use of VOIP PBXs, also known as IP PBXs, which use the Internet Protocol to deliver voice calls.
Types of the PBX system
There are four different ways to use a PBX phone system in today’s market: analog phone PBX, VoIP PBX System, a Hosted PBX system
Analog telephone PBX
A PBX is a private branch exchange that completes the exchange of telephone calls between companies and with the public telecommunications network and combines the functions of a telephone, fax, modem, etc. Users of a PBX telephone system can communicate internally (within the company) and externally (with the outside world) using different communication channels (e.g. voice over IP, ISDN, or analog). A PBX or PABX also allows you to have more calls than a physical telephone line (PTSN) and allows free calls between users.
It also offers call forwarding:
- interactive voice menu (IVR)
- calls queuing
The Benefits of an analog telephone PBX system
Saving money on intercoms: dealing with line switching within the system and thus reducing call charges.
As subscriber exchanges became more popular, new features were added such as intelligent line finding, subscriber calling, extension calling, etc., which were not offered by the telephone companies. Dialing extensions, etc., which were not offered by the telephone companies.
VoIP PBX system
VoIP is also known as IP telephony or broadband telephony and the Internet Protocol Telephone Exchange (IP-PBX) is an implementer of VoIP technology.
IP-PBXs are more open and standardized than traditional telephone exchanges (PBXs). Being IP-based, IP-PBXs can be networked remotely to address the communication needs of large organizations between their headquarters and branches.
Internet Telephone Exchange IP Outside Line Features
- Gateway: directly controls the phones connected to the device, detects phone status, dials numbers, transmits voice to and from the phones; controls the DSP, and plays sound to the phones.
- Call Control: Receives signaling, judges it, converts it into an internal message, or constructs a new one to send.
- IP outside line: Interoperate with devices outside the system via the IP network.
- Registration Module: Provides address mapping of registered devices.
- Web server: view system status and set system parameters from the web.

On-Premises & Cloud PBX Systems
Cloud PBX is a business telephone system. hosted and powered over the internet, rather than being built on a local LAN. A Cloud PBX can offer more features than a traditional PBX phone system, while making it easy for non-technical administrators to set everything up.
Cloud PBX supported by VoIP
Cloud phone systems use Voice over Internet Protocol (VoIP) technology to make and receive calls. VoIP technology uses the Internet to route phone calls between endpoints, using the industry standard of Session Initiation Protocol (SIP) to establish calls between phones.
Cloud PBX for unlimited integration and functionality
With a cloud-hosted PBX, all the services, features and functions of your phone system are accessible via the internet, rather than through complex technology, cables and switches on site. This also means that any new upgrades and features released by your service provider are added to your phone system immediately. Software updates make it easier to integrate new features than traditional PBXs, which require the physical replacement of old hardware.
Cloud PBX supports better phone system design and call management
In Cloud PBX, telephone system services and call flow routing commands are run in an off-site data center. The lack of on-site hardware opens up a new world of design possibilities. The hosted PBX works with your existing internet connection and even desk phones are optional. Businesses can choose between IP phones, softphones, and mobile devices.
It offers a mobile application that enables users to connect to the cloud phone system from their mobile phones. Work phones and personal phones are separate. As there is no need to configure a physical PBX, calls can be routed to an IP phone using a simple online drag-and-drop editor.
Geo-redundancy for a more reliable phone service
Cloud telephony systems use multiple data centers in decentralized geographical locations to house servers for failover redundancy. Redundancy means that our data center servers have exact copies, so if one server fails, it can be automatically replaced by another (failover) to avoid downtime. This setup also allows for more efficient call routing so that multiple office and mobile users can receive high-quality calls regardless of their location.
Why do modern companies choose to cloud IP PBX solutions
Affordability, flexibility, scalability, and simplicity are the reasons why organizations such as schools, governments, and enterprises use cloud communications. On average, it can reduce costs for new customers by 30% to 75%. These cost savings can be seen in organizations switching from on-premise systems as well as other unified communications providers. With our unique and scalable pricing model, there are no user fees to pay, and instead, there is an efficient usage model. Cloud PBX converts a capital expenditure (CAPEX) model with significant upfront and ongoing IT maintenance costs into a scalable monthly operating expense (OPEX)
The benefits of a cloud PBX for your business
- Enterprise-class telephony services, features, and functions are more extensive and less costly than traditional PBX systems (30-75% lower cost).
- Modern VoIP technology to transport calls and SIP to route them.
- The phone system is hosted in an off-site data center rather than on-site, which means no hardware maintenance is required.
- Flexible use of IP phones, virtual phones, and/or mobile phones from any location.
- Ease of use for remote operation of all aspects of phone set-up, configuration, routing, call service, and permissions throughout the system via a web browser.
- Geographical flexibility allows everyone to use phone lines from any location.
- Data center redundancy allows for near-zero downtime.
- Technology must be cost-effective, easy to use, and help you run your business better.
