What is a Softphone?

    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

Softphone vs Webphone

    Softphone: An internet phone that can be used on any IoT device—whether in a web browser, desktop app, or mobile app.
Webphone: An internet phone that can be used in a web browser only or you can say voice over http.
All webphones are softphones, but not all softphones are webphones.

    A SIP softphone is a software program for making telephone calls using SIP-based (Session Initiation Protocol) communications, basically listens on port 5060 UDP and for RTP traffic relies on port 10000 to 20000 UDP

    A IAX Softphone is also similar to SIP softphones, but they listen on the port 4569  and RTP traffic also flows over same port

    A PJSIP softphone is also similar to SIP phone but they support the PJSIP protocol, which is alternate or enhanced version of SIP

    Webphones are web-based applications that allow you to make phone calls directly in your Internet browser like Firefox, Chrome, Safari and many more. The webphones are based on WebRTC technology
