Hello..
I think so. I think it might be a good idea. However, you need to know if people are going to welcome these calls. Believe nothing better than talking instead often write. Nowadays in the online world there are a lot of information. What hinders people's attention on something specific unless it is something of great interest.
As a suggestion to save with calls, make a Premium subscription of Skype. Is very cheap.
Success with SFI.
Best regards!
