What is IP PBX?

An IP PBX is a private branch exchange (telephone switching system within an enterprise) that switches calls between VoIP (Voice over Internet Protocol or IP) users on local lines while allowing all users to share a certain number of external phone lines.

Most of the analog phone systems use wires and connectors that require specific expertise and tools to function. IP phone systems, on the other hand, are easier to connect together, as they use Ethernet cables as connectors.

IP PBX’s go a step further and allow you to add / remove components such as video calling, follow me, IVR, TTS / ASR, conferencing etc.

Strength of Voice Over IP (VoIP) shines especially when there are multiple offices that need to talk to each other. Normally, a call would need to be routed through your phone service provider, however thanks to VoIP, you can connect your offices over the internet, without any additional charges, all over the world. The only requirement for both offices would be a working internet connection and an one IP PBX Server installed (on premises or on cloud).

You can use either hard phones (Hardware phones, but with Ethernet ports), DECT phones or soft phones (software phones, where a software is installed on a computer and you are able communicate simply using a headset with a microphone). It’s even possible to use a smartphone such as android or iOS to connect to an IP PBX Server and talk normally using your phone. You can choose any method that meets your needs and budget.
