What is IP PBX

IP PBX is an Internet Protocol Private Branch Exchange, An IP PBX or Virtual PBX is a system that allows businesses to utilize the power of the internet to route and switch telephone calls. This means you can use VoIP to connect your office phone system. This is done through a simpler and better telephony server.

If you think about it, every phone line, every computer terminal, and every mobile device in existence needs to communicate with another network in order to function properly. In the early days of the telephone, sound-proof rooms and walls were built to isolate conversations from distractions such as passersby and animals.

Fast forward a century and we can see that creating such walls no longer makes sense as technology develops beyond our comprehension. IP PBX (Internet Protocol Business) is a protocol that enables private and protected phone lines to connect to public networks using private rather than public IP.

IP PBX: How it works

IP PBXs use the internet to make and receive calls. As a result, it converts analogue voice signals into digital signals. After that, it routes calls to a VoIP service provider, which handles call initiation and termination.

In essence, IP-based voice services are based on Session Initiation Protocols (SIP). It is now the standard protocol for VoIP phone systems. With a PBX, you would utilize SIP trunking, which has multiple channels for voice communication.

This remains unchanged on the inside of PBXs. Calls among users can be made, voicemail can be checked, and call groups can be created as before. By design, it’s like that.

In the case of a PBX, a VoIP provider is likely to provide credentials for one or more SIP trunk accounts. After authentication, your PBX accepts incoming calls. Using your SIP trunk, users can also reach an outside phone number.

Whether a call is handled internally or relayed to the PSTN depends on the PBX.

IP PBX: Features

IP PBXs are open-source, scalable, cloud-based telecom systems enabling businesses to pool resources into a single data network with centralized control. IP PBXs have a wide range of features and can be used for remote VoIP, PBX modifications, multi-location management, and international calling over broadband.

IP PBX: Benefits

VoIP PBX systems are used by small businesses and consumers to transmit phone calls over open-source networks. It is not unique technology as IP PBXs use the same servers as internet providers, but with a variety of distinct IP features. Sometimes they are confused or compressed with VoIP providers, but they are actually two distinct products.

The following are the benefits of adding a VoIP gateway to your PBX.

  • Cost-effective communication
  • Reliable cloud-based services
  • Existing hardware is retained
  • High voice quality
  • IP PBX increases the flexibility of management
  • More features for business users

When you install an IP PBX, you’ll immediately notice the difference compared to traditional phone systems. You’ll be able to make crystal clear calls from anywhere in your building or facility, and you won’t have to worry about those annoying static issues that come through on regular landlines.
