Virgin app allows landline calling over Wi-Fi

It is charged to your home phone. After we were charged 25p for a 13 second phone call, I wouldn't trust Virgin with phone calls. When we queried it, we were told it was the connection charge.

From the article i linked to;

"SmartCall is being positioned as the UK’s first Wi-Fi calling service, it allows customers to use calls from their home phone talk plan, be they at a friend’s, or even abroad."
