What is a VoIP phone number?
The VoIP phone number is basically similar to other phone numbers we are familiar with. The fixed telephone number can be used by the copper wire on the PSTN, and the mobile number is used on the cellular network through the handheld device.
Similarly, a VoIP phone number is basically an identifier for making a call on a VoIP network.
How does a VoIP phone number work?
As a relatively new term, not many people know what a VoIP phone number is, but it will be familiar to those working in technical work. For end users, the phone number looks and works the same way as other numbers.
It is a string of numbers that you can type on the dial pad and connect two people you want to talk to. There is no need to learn technical knowledge when using VoIP phone numbers.
VoIP devices are essentially plug-and-play, meaning that IP phones can be plugged into any available LAN port and the device will automatically register on the network.
Since then, this number can be used as usual. It allows users to carry their phone number with them wherever they are.
Based on the SparkleComm unified communication platform, SparkleSoftphone fully integrates voice, video, telephone, messaging and mail functions, and can be installed on the software client of smart phones and computers (PC/Mac).
The difference between VoIP and ordinary phone numbers
However, VoIP phone numbers differ from normal numbers in some very important ways:
Perhaps most importantly, the area code is not actually associated with the VoIP network. VoIP phone numbers work independently of location, and there is not much difference between local, national, or international numbers.
Telephone operators typically use area code assignment numbers to determine the rate for a particular call. With VoIP, users can choose a phone number with any area code (as long as the operator can provide it) because there is no actual difference in price, whether using the same area code or a different area code.
A fixed phone number is usually associated with a specific device, whether it is a home phone, an office phone, or any other landline phone.
VoIP phone numbers can be connected to multiple devices so they can be used in a unique way. Therefore, users can make calls from their desk phone, their smartphone or computer using the same number.
Such systems allow users to be flexible, especially in a business environment. VoIP phone numbers are better suited to the way we work and live in today's modern world.
