PBX, short for Private Automatic Branch Exchange, is a key component in a company’s communications, as it allows the creation of an internal telephone network that makes the work routine easier and more efficient.
To help you understand a little better how these devices work, we have prepared a guide that details what this system is, the different types that exist, and all the advantages it can bring to your company. Check it out!
What is a PBX?
A PBX is a device that connects to a telephone operator, similar to a regular telephone. However, it also allows connection to other internal lines, known as extensions.
In addition, with this system, it is possible to automatically route external calls to selected extensions and make simultaneous calls, ensuring faster and more efficient communication.
The flexibility and ability to integrate with different communication systems and technologies make PABX an indispensable telecommunications tool in various sectors of society, especially in the corporate world.
Types of PBX
There are three main types of telephone exchanges available on the market: analog, hybrid, and IP (VoIP). Below, we will explore the main differences between them:
Analog
Analog PBX is the most basic and affordable model of the three, making it the best alternative for small and medium-sized businesses looking to improve their internal and external communications without major investments in technological infrastructure.
This model uses traditional analog switching technology and connects internal extensions and external lines through physical copper circuits. Check out some of the main features of analog PBX:
- Caller ID;
- Call transfer;
- Conference calls;
- Automatic answering (DISA);
- Voicemail;
- Call history log;
- Collect call blocking;
- Economy extension;
- Possibility of integration with billing software (Controller);
Although it offers basic features compared to more advanced models, the analog PBX is a great option for companies looking for a cost-effective solution to help them manage their internal and external communications.
Hybrid
As its name suggests, the hybrid PBX combines the functions of analog, digital, and IP systems in a single device, allowing the company to use each of them according to its needs.
In addition, it has a relatively simple configuration and can be integrated with other systems or computers. Here are some features of this model:
- Supports a larger number of extensions;
- Features automatic line selection;
- Ability to connect to electronic door phones;
- Digital automatic answering system via IVR;
- Possibility of connecting the head office and a branch office via VoIP technology;
- Compatibility with IT systems and data networks;
- Scalability for expansion as needed.
IP
IP PBX uses Voice over IP (VoIP) technology to transmit phone calls from one point to another over an internet network. Due to the number of advanced features and its ability to easily integrate with other networks, it is an excellent alternative.
Here are some of the main features and functions of this system:
- Transmission of voice calls via the internet;
- Reduction in communication costs;
- Possibility of using the same internet cabling infrastructure;
- High-definition voice calls;
- Possibility of transforming a cell phone into a mobile extension using applications;
- Capacity to support up to 700 extensions.
Due to its relatively high cost, especially when compared to analog systems, IP PBX is usually recommended for medium and large companies that need this entire structure and range of features.
Cloud
Finally, there is Cloud PBX, which, unlike previous systems, uses cloud infrastructure to manage calls, eliminating the need for physical devices or software installed at your company.
In addition to offering a wide range of features, because it is a cloud-based system, the initial investment required is relatively low and its configuration can be done quickly and easily.
Here are some other features and characteristics of this model:
- Convenience for adding and changing extensions;
- Option to configure a voicemail box for each extension;
- Web voicemail;
- Call Center system with automatic dialer, DAC, and IVR;
- Screen recording and voice call recording in general;
- Possibility of integration with CRM and other business applications;
- Unified messaging;
- Call queues;
- Call reports and analysis.
