A softphone is a software phone that lets you make calls over the internet from a computer or other smart device. Conversations usually take place through a headset or a microphone and computer speakers. In most cases you will find a softphone used in conjunction with a hosted VoIP service.
There are many softphones available on the market which will work with WebFones. We recommend Bria 3, but any phone that supports the g729 codec will work well.
