VoIP systems allow you to make calls using an application

 Most VoIP systems allow you to make calls using an application on your computer or mobile device. However, you may choose a desk phone, and if so, you will be required to connect the phone to your network. Additionally, your service may require a physical private branch exchange (PBX) box. Most small business VoIP systems will host your PBX on their servers, in this way there is no need to have additional hardware in your office. But if you do get a PBX box, it usually comes with an installation manual, and you will need to connect the device to a power source and your office router using an Ethernet cable. Once the system is set up, you will be able to connect the phones to the hardware.

If you do not want a new number, you can use porting services to keep your existing phone numbers. Number portability is a way to transfer phone numbers from an existing service provider to a new one. You can learn more about porting here.

If you did everything right and have a fast connection, you will not have any problems. But you should still try and test your lines, especially when the network is busy. Network congestion can cause a variety of line problems, from dropped calls to poor audio, and more. Things you should pay attention to when making a call are sound quality, sound delay, and connection stability.

And that is it. If you completed these steps, your computer science engineering phone system is good to go. Hopefully, this guide has helped you decide whether or not to choose VoIP services for your business. Most importantly, know what you want from your VoIP system. Remember that each VoIP system is unique and can be adapted to the requirements demanded by its users. What works for you may not work for others. Good luck!
