After introducing its real-time communication framework, WebRTC, earlier this year, Rebtel (News - Alert) announced HD Voice for its iOS and PC Apps. HD Voice users can experience high sound quality when making free app-to-app VoIP calls over data networks – even in cases of slow-connection.
Rebtel HD Voice leverages open source voice codec technology iSAC (internet Speech Audio Codec) in its latest suite of iOS and PC applications, and is now listed in the iTunes App Store.
“Historically there’s been a general perception amongst consumers that VoIP services offer sub-par quality in comparison with traditional operators,” said Andreas Bernström, CEO at Rebtel. “Since these services are typically free of charge, consumers have accepted a downgrade in quality. Thanks to HD Voice technology, the maxim, ‘you get what you pay for,’ no longer applies to calling long distance.”
In a survey conducted by Rebtel early this year, they polled 992 U.S. mobile users. Eighty-nine percent of the surveyed users gave high importance to clear call connection, and 78 percent expressed their desire to switch carriers due to poor network performance. Nearly 40 percent of respondents also claimed to experience more than five dropped calls a month.
ased on this customer feedback, Rebtel focused its latest product, HD Voice, aimed at improving upon end-user experiences.
“Consumers typically resort to VoIP for specific use cases, such as when calling internationally to friends and family, and based on research we conducted, call quality is a hugely important feature for them,” said Bernstrom. “With major improvements to the Rebtel service, we can confidently say Rebtel’s voice quality is on par with operator-powered services, but either at a fraction of the cost, or absolutely free.”
iSAC is a wideband voice codec, commonly used in various types of VoIP applications. It was originally developed by GIPS (Global IP Solutions (News - Alert)), and became available as an open source technology as a part of the WebRTC project when Google acquired GIPS in 2010.
Among the many benefits of iSAC is its ability to adjust to the user’s bandwidth conditions and not rely on a high-speed data connection in order to facilitate crystal clear, high-quality voice calls.
