Mobile Phone PBX

What is a mobile PBX phone system?

PBX stands for Private Branch Exchange and this is a telephone network used within organisations to keep internal and external communications running smoothly and efficiently. When being used to communicate with those external of the organisation, different communication channels such as Voice over IP, ISDN or analog are usually integrated.

Using a PBX phone system in an organisation can substantially reduce costs because it allows free calls between use while also providing your company with more lines. It will normally come with popular features such as transfer calls, voicemail, call recording, interactive voice menus aka IVR and also management of call queues.

Generally speaking there are three types of PBX phone systems and these are:

An Android phone with a fully customized native application that runs with a cloud-based PBX system

Mobile phone applications that work with a cloud-based PBX system

Using feature to direct phone calls to your current mobile phone number.

Below we will look more closely at the uses and advantages of these mobile phone PBX systems.

Android phone with a fully customised native application that runs with a cloud-based PBX system

Today, with the latest developments in technology you can now use your android phone as a fully blown mobile phone PBX system. You can use apps that will provide you with these features. The apps can use an open-source SIP client that adds native SIP/VoIP to your android phone’s default dialler. Once you download such an app you are then able to make and take calls over Wifi and 4G/LTE data connections.  

For start ups and SMEs this is a popular go-to telecoms solution because it will save on costs and allows a company to set up a private internal phone system. Because it uses a data connection this option is therefore not a very secure one. A mobile PBX system is a hosted PBX where mobile phones basically operate as phone extensions. VoIP phones can also be integrated with a PBX solution. A mobile PBX system takes phone calls and diverts them to the landline or mobile cellular line.

Imagine that your sales guy is pitching to potential clients while the tech support guy is away from his desk and on his way to serve a client. Accounts person is on holiday leave and your developer works remotely. Always and at any time colleagues are going to be out and about and on the move. In order for employees to have the freedom to move around while still effectively communicating as though they were still at their desks, it makes sense that employees should be able to link their mobile devices into an office PBX phone system, allowing them to connect and communicate as if they were at their desks. There are many practical benefits with this type of popular feature and relatively straight forward and easy to use. 

Popular uses are:

1 – Forwarding PBX calls to your mobile smartphone anywhere in the world instantly or after a few rings…and hey presto you have managed to be able to answer calls whenever you are away from your desk.

How is it done and is it easy?

With all PBX systems you just navigate to the redirection option and Enter your cell phone number or number to which you wish to forward the calls. You can even forward any pagers or door buzzers that you have connected. Of course another handy option is that you can also usually enter numbers that you do not want receive calls from.

2.Tell the difference between PBX and mobile phone calls

In order to distinguish between a PBX forwarded call and a normal call to your mobile, you can normally choose to have a special system that will only kick on only when an office call has been forwarded to a mobile phone.  Also, the menu will give you the choice to take the call, decline the call or send it to voicemail. If you miss a PBX call, the voicemail will go to your office PBX system and send a voicemail to email. And if you don´t have that particular feature you will find the voicemail message on your mobile phone as normal.

  1. Make a PBX call from your mobile phone

When Making a PBX call from your mobile device you will normally be prompted by an automated assistant. So when you need to be away from your desk phone because you have to leave the office, you no longer have to miss those important work related calls! You now have the power to simply forward   incoming calls from your desk phone to any mobile number you want. In the same token, you can also make all your business calls from your mobile phone as if it is from your desk. More freedom and flexibility!

The other thing is that most people assume using a PBX system is going to be difficult to navigate and will be costly. However that is far from the truth! Most PBX system are super user friendly and are actually budget friendly too! So now you can get the best of technology and have everything integrated and centralised on your mobile phone. With each passing day, technology is shaping how organisations are run. Advancement in technology can bring about major changes in how efficiently and effectively an organisation functions. A mobile phone PBX system is one such technological advancement that has helped businesses and organisations of all sizes to improve and thrive.

Everyone regards Privacy as important and are always looking for ways to protect it. One way of achieving it is by setting up and configuring aVPN network. Or if you still have concerns we will discuss another option below.

An app for mobile phones that works with a cloud-based PBX system

Another way to make your phone serve as a fully fledged mobile phone PBX system is by downloading one of the many applications available. And another bonus is that they are usually free!  Other advantages of doing this are:

The calls are totally different from ordinary phone calls which means you will be able to distinguish how to answer and deal with each call.

The dialer for VoIP calls is different. As before you will be able to distinguish these as well and know what type of call to make and take.The setup is pretty easy and once you are done setting it up, all there is left to do is walk through your office door, because it will connect itself to the WiFi automatically and registers itself to the PBX system. You don’t have to receive calls when you are at home.  To ensure this, the system disconnects itself once you are out of your office space and WiFi network, so the calls automatically go to voice mail. Therefore, you do not have to worry about carrying office work to home on your mobile phone. You can use the device via cell data as well. The settings allow you to change the network to your mobile data if you are willing to bear the charges. Thus, you can use this as your desk phone anywhere and anytime. For this to be possible, your phone has to be WAN accessible. Additional benefits and features of this android application are caller ID, transfer commands, and video calls.

Choosing the number of rings and time:

By the call forwarding feature, you have the freedom to choose after how many rings the call shall be forwarded and can in addition choose specific times when calls can be forwarded.

Distinguish between PBX and cell phone incoming calls:

The system will allow you to differentiate between your personal and official calls. The special system menu will activate only when an office call is forwarded to your cell phone. This will also give you the options to connect or reject the call.
