What is an IP PBX system?

An IP PBX is a telecommunications device that connects desk phones in a building to offer voice connectivity. It uses an internet connection to manage outgoing and incoming calls throughout its telephone network.

Let’s take a closer look at this definition. IP – Internet Protocol (IP) is a protocol for sending data from one server to another. Calls are established over the internet using this technology.

PBX (Private Branch Exchange) – A PBX (Private Branch Exchange) is an internal telephone network. A PBX can be installed on-premises or securely hosted in the cloud.

An IP PBX phone system allows you to make and receive calls via the internet while keeping your analog phones throughout the office.

Open-source solutions that need Linux knowledge can be used to configure a PBX. You should also be familiar with call routing and have experience with Asterisk-based PBX systems. This method has numerous advantages and disadvantages. It is not suitable for everyone.

 

What is an IP PBX and how does it work?

 

IP PBX phone systems use the internet to make and receive calls. It accomplishes this by transforming analog voice signals into digital signals. It then routes calls to a VoIP service provider, who manages the call’s beginning and termination.

Session Initiation Protocol (SIP) is at the heart of IP-based telephony services (SIP). For VoIP phone systems, this universal protocol has become the de facto standard. SIP trunking, which provides numerous voice channels, would be used for a PBX.

On the inside of a PBX, nothing has changed. Users can make phone calls to one another, check voicemail, and create call groups just like they could before. It’s on purpose.

A VoIP provider would supply a set of credentials for one or more SIP trunking accounts on the PBX’s external side. Incoming calls are presented to your PBX for acceptance once they have been authenticated. Users can automatically dial an outside phone number using your SIP trunk.

The PBX decides whether calls are handled internally or forwarded to the PSTN.

You should be aware of its limits, but first, consider the benefits of incorporating a VoIP gateway into your PBX.

IP PBX systems have the following advantages:

Adopting an IP PBX in your company can have several advantages. Here are a few reasons why it’s a good idea to invest.

Lower communication costs – Internet-connected PBXs can save a lot of money compared to their analog counterparts. Nextiva, for example, offers both metered and unmetered trunking services.

Cloud-based resiliency – Connect your existing PBX to the cloud’s proven resiliency. For stable performance, a trustworthy VoIP service will include many data centers. They can divert calls elsewhere even if your PBX is unavailable.

Uses current hardware – By using the same gear that’s already connected to your PBX, you can keep everyone working while lowering your hardware costs. All you need is your SIP address, password, and domain to get started.

Minimal change – Many firms are afraid of change. Consider SIP trunking as a method to get a taste of the benefits of a VoIP phone system. With minimal configuration, you may scale up the number of voice channels as your organization grows.

Assume that you or your IT department is already familiar with PBX phone systems. An IP PBX could be a clever stop-gap option in this instance. Furthermore, because SIP trunks are location-neutral, you can get up and running quickly if you relocate offices.
