All You Need to Know About IP PBX System Software

Effective IPPBX System

Whether you are considering adding a new business phone system or moving from the present Private Branch Exchange (PBX) to a cloud-based trunking provider for PSTN connectivity, you first need to understand how things are working. 

You might think that implementing IP PBX is an easy task, but it’s not the case. After all, you don’t want to come up with a new set of problems with incoming calls. In this article, you’ll learn about the IP PBX system, how it is different from VoIP, how to implement it, and some of the limitations of IP. 

What is an IP PBX System?

 An IP PBX is a private branch exchange means it is a telecommunication device or a system that provides voice connectivity to desk phones within a fixed area like a building or an office. 

IP PBX system takes incoming and outgoing calls across its telephone network using an internet connection.

Let’s breakthrough the term IP PBX understand more about it: 

  • IP: Internet Protocol is a calling technology that works over the internet, and it transmits data from one server to another server to connect the call. 
  • PBX: It is an internal telephone network that can work in two ways, either on-premises or cloud-based. PBX is also known as Private Branch Exchange. 

How does an IP PBX work? 

An IP PBX system works over the internet, and it places calls and receives calls by converting analog voice signals into digital. After converting the signals, it’s a direct call to the VoIP service provider to manage the calls. 

Down the line, IP-based voice service uses Session Initiation Protocol (SIP). For VoIP phone systems, SIP universal protocol has become a standard. SIP trunking can be used for the PBX system to use multiple voice channels. 

There are no changes internally; people can call each other, check voicemail, and set up call groups as they could before. On the other hand, externally, to use multiple trunking accounts, a set of credentials would be needed the VoIP providers would provide that. After the authentication is done, incoming calls are presented to your PBX to accept. Do remember one thing users are also allowed to reach an outside phone line by way of your SIP trunk automatically.

A PBX system can automatically determine whether calls are handled internally or relayed over to the PSTN.

Benefits of IP PBX systems 

Added in an IP PBX system is quite beneficial and can add some extra features to your business. Let’s see some of the best benefits of IP PBX:

Communication costs get reduced: Using an IP PBX system can drastically decrease the cost of calling compared to the traditional analog method. Many VoIP providers offer both metered and unmetered trunking services.

More reliability due to cloud-based technology: If you use an excellent PBX and VoIP service, the system reliability increases because of multiple data centers that can provide dependable performance. Also, if PBX goes down, there is an option to route call some elsewhere. 

Can work with existing hardware: You can keep the same hardware so that you don’t have to pay that hard-earned money on that costly hardware. You can easily use the old hardware already attached to the PBX. You just need to provide your SIP address, password, and domain, and you’re set.

Doesn’t need heavy changes: Changes are a difficult task for that companies. With IP PBX, you can add voice channels as the company or process grows. 

Limitation of IP PBX System 

Although IP PBX is still a great option to go with. Still, there are some limitations that a user can face while using the IP PBX system. 

Need Some Technical Skills: If you want to use a cloud-based IP PBX system, you don’t need high technical skills, but still, you need some base knowledge of how things are working. On the other hand, if you are going to use an on-premises IP PBX system, you need a high understanding of technology. Because you need to install and configure Linux operating systems to use IP-PBX. Also, to maintain the system properly, you still need technical skills. 

Unable to work remotely: It is hard to set up a calling feature for remote employees if you are using on-premises IP PBX. The cloud-based version allows you to do that properly.
