  1. Dedicated apps are cool but webapps are better. There is software called Ghoscall that works good. However both users need the software installed on each endpoint/machine. Roboshout is good because it works on iOS, Android, and Desktop browsers.
    There’s a few apps that are ok but only if you pay for them… anonym call is one… I heard it wasn’t so great though.
