The Functions of PABX

Here are some of the functions of a PABX that support the improvement of your business communication:
1. Manage incoming and outgoing calls
Incoming calls from customers and business partners can be easily managed by a Private Automatic Branch Exchange (PABX). The system can also automatically connect calls to the department associated with the extension number. With features such as an auto attendant or being connected by an elderly receptionist, calls can also be automatically connected to the destination.
For outgoing calls, the PABX can also perform recording. Because the outgoing phone lines are on one line, the use of the phone by employees can also be controlled.
2. Managing internal communication
Another function of PABX is that it can manage internal communication well. This system allows calls between employees in one company only by pressing the extension number, without having to connect out. That way internal communication can save time and money.
3. Reduce operational costs

PABX can function as a reduction in operational costs because PABX allows internal users to share external lines so that telephone subscription costs can be reduced. In addition, internal calls through PABX are not subject to additional fees so they can be profitable for the company.
4. Support monitoring and documentation
Support monitoring and documentation is another function of PABX. With call recording features, call logs, and usage statistics, management can easily evaluate, conduct training, and document conversations to improve customer service.
5. Supports flexibility and scalability
Another advantage of PABX is its ability to support flexibility and scalability. PABX systems can be developed following technological advances without having to change the entire infrastructure.
What needs to be added in the development of advanced technology from PABX is a new extension or expanding server capacity. Its flexibility and scalability make PABX ideal for long-term use.
Those are the functions of PABX that you need to know. Another thing to note is that PABX on the market must pass the certification test from the Directorate General of Digital Infrastructure (DJID).
With DJID certification, users can feel calm about using PABX technology whose quality and security are guaranteed. For manufacturers or importers of PABX technology, obtaining certification from DJID is a mandatory step before the device can be officially marketed in Indonesia.
To simplify the certification process, Type Approval Certification Services for ICT Products are available to assist with this process as a reliable solution.
