What IP PBX system is?

An IP or PBX switch for “Private Branch eXchange” is the evolution of the old TDM-based switches; a private telephone network that used within a company. At present, the era of Unified Communications, IP switches are no longer straightforward voice platforms as they were before. A fragile line separates Unified Communications and IP Telephony.

There are currently four different telephone system options:

  • PBX
  • Virtual PBX Service
  • IP PBX
  • Virtual PBX IP Service

An IP PBX is a software-based IP switch that allows you to achieve various functionalities and services that are usually very difficult and expensive to implement with a traditional proprietary PBX.

An IP PBX system consists of a switchboard that allows you to connect a switchboard to the telephone network via the Internet (called SIP trunk) and in the combination of virtual phones (softphones), desk phones, mobiles or computers, as well as the PBX , which can be software installed on a server within the network. Like a regular switchboard, Company itself owned and managed the IP PBX systems.

The only difference is that the company is connected to the telephone provider through SIP trunks, instead of the traditional telephone lines.

PBX Phone System

Traditional PBX technicians would have their proprietary phones, so there would be no way to use these phones with a different system. This means that either we have a system-lock-in (we are limited to the same network since a system change also means changing phones, which makes it prohibitive and high cost) or a vendor-lock-in (we are limited to the same manufacturer because phones can only use with that manufacturer’s systems, sometimes only with a particular range of operations).

Technology and time, anyway, have changed the landscape of telephony use, with the IP PBX based on open measures that will lead this field.

 

How does IP PBX work?

Knowing that a vocal conversation is an analog signal and that the internet carries numerical data, it is necessary to transform the voice into a digital message. It is the role that an IP PBX installer performs.

It will digitize the acoustic signal, compressing it thanks to code, and dividing it into data packets. This stage is critical since it is the one that allows the message to be transmitted instantly to the interlocutor. Once the Packets sent, they become digital signals, and then analog signals.

An IP PBX contains one or more VOIP/SIP telephones, an Internet Protocol PBX server, and also a VoIP Gateway.

Advantages of IP PBX?

An IP PBX is a type of PABX that uses the IP protocol. The difference between these two business telephony solutions is not limited only to their operation. The integration of the Internet into a telephone system offers numerous additional functionalities. Depending on the chosen offer, you can access more than 500 extra services. For example, IPBX provides the possibility to customize your music on hold. It is not possible in a system managed by a PABX. Within this configuration, it is necessary to call an external provider, which translates into additional costs for your telephony.

When a PBX installed in a company, integration costs can rise quickly. Between installation and configuration, an expense estimated between $50 and $100 for the connection of a telephone to the switchboard. The higher the number of phones to connect, the greater the bill.

On the contrary, an IP PBX managed by software. Once the equipment installed, easily connect the phones to the network, to integrate it into your telephone system. Therefore, you will not be obliged to use external suppliers for each new line, which represents substantial savings.

VoIP Technology – Evolution

As the internet ongoing to develop, new possibilities come into existence. Instead of controlling calls to IP PBX appliances, VoIP systems allowed to communicate between systems, phones, and IP phones. This new system is cloud-based, and an outside service providers host’s it. It works as an application, offering communication for multiple channels. Users can video chat, share their data, an instant message, and many more. They could do that from anywhere, till they had on hand a device connected to the Web.

The VoIP system also allows companies or businesses to unite their communication with other applications. Salespeople could now track calls within CRM systems and use notes from previous conversations. Communication became connected, and the possibilities endless.
