The disruptive FTTH operator Lyse Tele (owned by Lyse Energi) teams with Comverse and Cicero to add mobile, effectively producing the quad play.
It includes wVoIP (the CiceroPhone client - not UMA but SIP based) and seamless WiFi/GSM roaming (voice only, mind you). At home, calls will be routed via WiFi to the BB connection. Outside the home, mobile will be ordinary GSM calls (Lyse doesn't own a 2/3G network), and usage will be limited to certain handsets, I presume.
I think the offering is interesting for 3 reasons.
(1) Cicero's seamlessness is a cool piece of tech, that (2) allows Lyse to offer wVoIP (basically for cheaper calls when in range of a free hotspot), without having to team with a mobile operator. (3) Users only need a single number. I am not sure how this would work out for existing Lyse subscribers, who already have two numbers (one Lyse, one mobile). Perhaps they can now drop the Lyse number.
