The free WP-WP is normal VoIP, but using best available practice
It is a massive marketing tool that replaces free minutes
By download WP and free calls to any other WP , the viral effect is significant to download numbers.
The marketing will have to be something like "make free WP-WP calls but if you want to call using our short haul VoIP try it now for x dollars for trial 5 minutes "
That's just a thought anyway .
But it's about user retention and acasionally these increased numbers which then cost us nothing in free giveaways will need to call a landline and then perhaps can option to upgrade their call I guess .
Looking forward to the app Annie figures to boot off the charts when this kicks us into overdrive .
