Jajah is a VoIP (Voice over IP) provider, founded by Austrians Roman Scharf and Daniel Mattes in 2005.[1] The Jajah headquarters are located in Mountain View, CA, USA, and Luxembourg. Jajah maintains a development centre in Israel.
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.
