High Quality Content by WIKIPEDIA articles! Jajah is a VoIP (Voice over IP) provider, founded by Austrians Roman Scharf and Daniel Mattes in 2005. The Jajah headquarters are located in Mountain View, CA, USA, and Luxembourg. Jajah maintains a development centre in Israel. On 23 December 2009, it was announced that Jajah had been bought by Telefonica through its subsidiary Telefonica Europe. Jajah's primary service, Jajah Web, takes an approach called web-activated telephony, using VoIP to connect traditional phones (landline or mobile). Calls are made without download or user-installed software, and in most cases at rates lower than those of traditional phone companies or even free of charge. The company’s competitors include Ribbit and IntelePeer.
