Telefónica has acquired Jajah for $207 million.

"Reports of the sale and its price had begun to circulate several days ahead of the official announcement," writes CNET News' Josh Lowensohn. "There were also rumors of an ongoing bidding war between Cisco Systems and Microsoft, which were competing with Telefónica for the sale."

"Telefónica's purchase of Jajah is the first of its kind for a major cellular carrier," according to Electronista. "It also signals the start of a new trend that sees carriers shift from the traditional voice service on handsets and towards Internet calling that will likely become common when 4G networks arrive in the next two years."

"The Jajah deal indicates that the world's traditional telecom players want in on the Web-calling game," notes BusinessWeek's Olga Kharif. "One of these telcos may want to acquire Skype in the future."
