What advantage does softphone technology provide for users?

Softphone technology is designed to enhance user flexibility and mobility by enabling users to make and receive calls from various devices and locations. This advantage stems from the fact that softphones operate over the Internet and can be installed on smartphones, tablets, laptops, and desktop computers. As such, users can connect and communicate regardless of their physical location, as long as they have an Internet connection. This level of accessibility supports remote work and facilitates communication for businesses without the constraints typically associated with traditional telephony systems.

The other options misrepresent the capabilities of softphones. Restricting communication to a single device contradicts the fundamental principle of softphone technology, which is meant to enhance connectivity across multiple platforms. The notion that extensive hardware is required is also incorrect, as softphones often rely on existing devices rather than dedicated hardware. Lastly, softphone technology actually aims to reduce costs associated with communication by leveraging VoIP systems, making it a more economical choice for users compared to traditional phone systems.
