How does Softphone App Work?

Now that you are clear with the idea about the definition of a softphone, it’s time to discuss the working of a softphone app. 

Primarily, a softphone app operates by converting analog audio signals into digital data, which is transmitted over the internet using VoIP technology. Here’s a step-by-step explanation of how it happens:

Installation and Setup of the Softphone App

The first step that you need to do is download the app from the provider’s website and install the application on whichever device you want to use i.e. computer, smartphone tablet, etc. Once the application is installed, you need to configure it by creating your account.

Having a strong and reliable Internet connection on your device is essential for using the softphone app. Your internet connection could be in the form of WiFi, ethernet, or mobile data, but ensure it has high speed. 

Audio Conversion

When a call is initiated using the softphone, the audio signal or the voice is picked up by the device’s microphone from where the softphone app converts this analog audio signal into digital data. 

VoIP Transmission

Now the digital voice data is packaged into data packets. These packers with the help of VoIP technology are transmitted over the Internet so that they can reach the intended destination. 

Receiving and Decoding of Digital Data

On the destination side, the softphone app of the recipient receives the transmitted data packets which are then decoded and converted back to audio signals. 

Audio Output is Received

The converted analog signals are received by the recipient and played through their device’s speaker which allows them to hear the voice message of the caller. 

Call Management Features

Softphone for business usually offer various call management features such as call recording, voicemail, and call transfer, which are quite useful for users, especially in business environments. 

Data Encryption and Security

Softphone apps ensure the security of data transmitted over the internet during calls by employing encryption protocols. With this, softphones keep unauthorized access and eavesdropping at bay. 

Features Offered by a Softphone for Business

A softphone allows users to do the following:

  • Make and receive Audio/Video Calls
  • Manage contacts – adding, removing, blocking contacts
  • Instant Group and one-to-one messaging
