Fring is nice VoIP application and i m using it from last 4 months the beauty is features and user friendly interface the only thing missing is mobile back service, which one of their competitor Vopium.com is offering. Fring should also go for that.
Yeah,I agree with you.I think Fring will add that feature up soon.
