Yes you are correct about outgoing calls to Skype. Since it's difficult to dial a Skype address from a phone I decided to add my Skype contacts as speed dials on
ippi.fr for simplicity. The calls seem to be very good. I have not had an incoming Skype call using them but that is possible as well.
To perform a free Skype to
ippi.fr call send a chat request to skype2ippi. Send a chat message to skype2ippi with the sip id of the
ippi.fr user name or ippi number you want to call.
ippi.fr will then connect both parties for free.
