Telecommunication and network security
A softphone is a piece of software that allows users to make telephone calls over the internet via a computer or smartphone. It has all the features of a desk phone and typically expands the range of services you can access on a desk phone. Most importantly, a softphone allows you to take your work phone with you wherever you go. It can be installed on a laptop, tablet or smartphone which allows you to leverage the same powerful performance and connection your work phone has. It facilitates mobile working, as you can continue to work on the portable device that you are carrying with you.
