Viber turns to SPIRIT for quality HD mobile VoIP calling

BARCELONA, SPAIN: SPIRIT DSP, the world's top voice and video over IP Engines provider, has announced that its TeamSpirit Voice Engine Mobile is powering the new Viber application that offers free HD Voice over IP (VoIP) calls from the iPhone.

"Within three days of launching Viber on the iPhone late last year, we received one million downloads, and seven million within the first month, quickly becoming the No. 1 free app in the Netherlands, Spain, Singapore, Taiwan, Israel and several other countries, validating the enormous demand for quality, free mobile VoIP calling," said Viber Media's CEO Talmon Marco. "We're incredibly pleased with this massive uptake and can credit SPIRIT's Voice Engine Mobile for the quality of the Viber voice experience."

Available in the Apple App Store, Viber's free mobile VoIP app can make calls over 3G and Wi-Fi connections, bypassing the use of any cellular voice minutes; calls are free worldwide. Unlike other VoIP services such as Skype, Viber requires no registration or need to log-in to make calls. Viber product releases for Android, BlackBerry and Symbian are now in the works supported by SPIRIT.

“The new Viber application is wildly popular in the mobile VoIP market as a serious Skype alternative, and we're thrilled that Viber Media chose SPIRIT's Voice Engine Mobile to ensure a quality calling experience for their users,” said SPIRIT's Chairman Andrew Sviridenko. “Viber's success amplifies the growing sophistication and demand for quality mobile VoIP, anytime, anywhere.”

SPIRIT's TeamSpirit Mobile enables HD-quality voice and video communications on a broad range of mobile devices, addressing all impairments inherent with IP networks - such as congestion, echo, noise suppression, latency, delay (jitter), packet loss, lip synchronization, etc. - to secure high quality voice over Wi-Fi, LTE/WiMAX and 3G/4G networks.

It includes highly optimized standard voice and video codecs, such as G.711, G.723, G.729, iLBC, SILK, H.263, H.264 and SPIRIT's patent-free wideband IP-MRTM codec. TeamSpirit mobile voice engine is available on all popular smartphone operating systems including iPhone iOS, Android, Windows Mobile and Symbian.
