I don't have a softphone or the gear to use it.
Just so you know (and for the sake of other readers) there is no special gear needed.
A softphone is merely software for your computer. There are many good free softphones.
I am sure that your computer has a speaker attached, even if you don't have an earphone.
The only other thing that would be needed would be a microphone. Most people do have some type of mike today....
