In recent decades, the private branch exchange PABX has become more democratic within companies. The PABX or Private Automatic Branch eXchange is a type of switchboard which has several advantages for companies. Whether inside or outside the company, the PABX improves communications in many ways. To tell you more, here is a quick overview of this revolutionary telephone routing technology.
How to set up a PABX solution?
Before setting up a PABX solution, do an audit of your business telephony and switchboard needs. In practice, define the type of telephone to use, the number of sets to install and the desired features. In general, the professional in charge of the installation analyzes your existing network architecture and then offers you options.
Following these prerequisites, proceed with the actual installation of your PABX solution. Here, the work evolves by following a number of stages. Among them, you have the deployment of equipment (patch cabinet, cabling, etc.), configuration of the network and telephone sets, tests and controls. At the end of all these steps, the PABX professional takes charge of the installation and then trains the users in the various operations.
How to use a PABX?
Once your PABX solution is up and running, you have two options for using it conveniently. You can use call center software that benefits from all the management properties of a physical PABX. Indeed, the call center software and its telephony techniques offer multiple facilities. A simple connection to the PABX system is enough to visualize the routing of all internal calls.
However, thanks to a PABX, you also have the possibility of routing your calls to external networks, in particular GSM, CDMA, UMTS and others. To do this, you will need to connect your operator via a dedicated gateway on the PSTN or ISDN network. Under this configuration, the system requires trunks (call gateways) based on number patterns. In other words, contacting external PSTNs via operator lines requires defining the numbering structure to be used.
What is the role of a PABX?
The PABX is a switchboard that automatically manages communications between several stations (internal and external). With a PABX, internal calls are free. In addition, you receive incoming calls in a distributed manner and the outgoing lines are distributed over several extensions. In other words, the PABX allows you to have more telephones than physical lines.
In addition, you benefit from many additional features such as voicemail, call transfer and interactive voice servers (IVR). You can even add call recording, queue and more features. The PABX optimizes the use of telephone lines so as to eliminate the costs of internal calls and automatically distribute the call channels to the outside.
