What is a PBX Phone System?

PBX stands for private branch exchange, it is a private telephone network used within company or organization. Users of PBX telephony systems can communicate internally (inside the company) and outside the company (outside world) using various communication channels (Voice over IP, ISDN, analog, etc.). The PBX also allows you to have more phones than the physical telephone line (PTSN), allowing free calls between users. It also provides features such as transfer calls, voice mail, call recording, interactive voice menu (IVR), and call queue.

Conventional PBX has its own private telephone, which can be reused in various systems. That is, locking the system (because changing the system requires replacing the phone, binding to the same system, the cost of deleting is too high) or vendor lock (binding to the same vendor). The same vendor's system may be available only within certain systems.

However, time and technology change the field of consumer telephony, standard bearers are based on open standard IP PBX. In this new era, the key to "IP" is to use the Internet protocol as the underlying transmission technology for delivering calls.

The PBX phone system can be used as a hosted solution or virtual solution or as an on-premise solution running on your own hardware.

This image gives us an idea of ​​the advantages of the IP-PBX system in terms of connectivity and reachability.

Traditional PBXs are typically restricted to the maximum number of external telephone lines (trunks) and a certain number of internal telephone devices or extensions. Users of the PBX phone system (telephone or extension) share an outside line for external calls.

Switching to IP PBX has brought a lot of advantages, enabling almost infinite growth of expansion and relay, and opens the possibility to introduce more complicated functions that are more expensive and difficult to implement using conventional PBX I will.

The Mobile PBX is a hosted PBX service that extends the fixed line PBX function to mobile devices such as mobile phones, smart phones, PDA phones, etc. by configuring the fixed line PBX function as an extended function. Mobile PBX service also includes fixed phones. The mobile PBX system in that it allows the cell phone itself to control the PBX phone function and to manage the communications using buttons, buttons and other input devices without having to transfer the data to the mobile phone It is different from other hosted PBX systems. First call the system

Traditional PBXs are typically restricted to the maximum number of external telephone lines (trunks) and a certain number of internal telephone devices or extensions. Users of the PBX phone system (telephone or extension) share an outside line for external calls.

Without a PBX telephone system, companies with multiple telephone lines and employees can not function effectively. Traditional PBX had to spend thousands of dollars on initial capital cost to install and configure outdated technology. Automatic operation is possible with some conventional PBX systems, but in most cases, a dedicated operator is required to manage the lines. Companies need to consider switching to the cloud PBX system to reduce overhead costs and not to hire unnecessary personnel. Since we can not purchase a "box" and the cloud PBX system is an affordable alternative to the expensive traditional system, there is little initial setup cost. In addition, employees can easily manage the system when changes are needed, thus reducing ongoing costs. No expensive technicians are needed.

PBX is an abbreviation for "Private Exchange", which is a telephone system that enables all users to switch calls among users on local lines while enabling all users to share a certain number of external telephone lines. Because each user does not need a leased line, the PBX system reduces the cost of the phone. A conventional PBX, also called a live PBX, requires a separate network for voice communication and data communication. Meanwhile, cloud PBX or hosted PBX uses a unified data and voice network, so VoIP and traditional telephony services can operate over the Internet connection.
