The terms describe two distinct methods for making and receiving telephone calls. One refers to a physical telephone device connected to a traditional phone line or a Voice over Internet Protocol (VoIP) network. The other utilizes software on a computer, smartphone, or tablet to perform the same functions. An example of the former is a desk phone commonly found in offices, while the latter could be an application like Skype or a dedicated business communication app installed on a laptop.
Understanding the distinction is essential for businesses and individuals when choosing communication solutions. The selection impacts cost, features, portability, and integration with other business systems. Historically, organizations relied solely on the physical option, but the rise of internet-based communication has made the software-based alternative a viable and often advantageous choice.
