Blueface differs from Skype in several ways.
Blueface allows you to use your phone in the manner you are accustomed to, similar to a traditional landline but with lots of extra services and features.
You also have the option to transfer your existing number to Blueface.
Unlike Skype, who bill per minute, Blueface bill per second which means you pay exactly for the time you spend on the phone. Blueface to Blueface calls are also free.
