Mobilkom Austria integrates GSM and SIP telephony

Mobilkom Austria announced a friendly customer trial called A1 over IP, which integrates the biggest Austrian mobile phone network with over 3 million customers and the world of SIP based IP-telephony. When somebody calls you on your A1 (+43664) mobile phone number, your mobile phone AND your SIP client rings. When you call somebody via SIP client, they see your A1 (+43664) mobile phone number via CallerID. IMHO, this is one of the most disruptive technologies, I have seen this year. Pretty amazing. The future starts now! BTW: Mobilkom Austria is said to start a HSUPA trial before the end of this year.
Update: on 11/17 Mobilkom Austria showed live HSUPA in Vienna and said they will deliver real HSUPA services in the beginning of 2007.
