What are Softphone Applications?

Softphone applications are software-based phones that allow users to make voice calls over the internet instead of using traditional phone lines. They run on devices like computers, smartphones, or tablets, leveraging VoIP (Voice over Internet Protocol) technology to transmit audio. Softphones offer a range of features, including call forwarding, voicemail, and conferencing, typically integrated with business communication platforms. These apps require only an internet connection and can significantly reduce costs associated with traditional telephony. With the ability to connect globally, softphones are ideal for remote teams, providing flexibility and scalability for businesses.
