Jajah, Telefonica's U.S.-based VoIP subsidiary, will officially stop offering services at the end of January.
On Jan. 31, the Mountain View, Calif.-based company said that customers will "no longer be able to make any calls through any of Jajah's services, including the Jajah.com website and Jajah Direct."
While it is no longer accepting new subscribers, current users will still be able to access their account and can apply for a refund before the service closing by submitting a request at its support page.
Founded in 2005 by Roman Scharf and Daniel Mattes, Jajah was acquired by Telefonica for $207 million in 2009.
What differentiated Jajah from other over the top (OTT) providers such as Skype and Vonage (NYSE: VG) is that its VoIP system did not require a user to download any software or purchase VoIP CPE to get the service.
Just this March, Telefonica's 02 UK subsidiary launched the Tu Go app. Leveraging the Jajah infrastructure, Tu Go enabled users to make and receive calls, texts and voicemail via the Internet using their existing telephone number.
The company did not provide a specific reason for its impending shutdown.
