Skype Users Get HD Voice Calls to Other VoIP Providers

High-definition VoIP and Skype are coming together on the back of Voxbone, a provider of international VoIP origination services and telephone numbers.

The Voxbone number service, iNum, now supports HD calling between dozens of VoIP networks and Skype, the company announced today. Voxbone will transcode, or translate, between Skype’s super-wideband SILK codec and the widely deployed HD codec, G.722.

The allowing of HD voice calls connecting across disparate service provider networks helps solve a big deployment hurdle for the technology. Skype’s 480 million registered users who have the latest version of Skype for Windows or Mac can experience HD quality not only in conversations with one another, but also when they call most of the world’s other HD-capable endpoints.

“With iNum supplying the needed uniform identifier across all providers, our support for Skype’s SILK codec kicks high-definition voice into higher gear,” said Tim Behrsin, Voxbone’s business development manager for iNum. “As we support more codecs, we expect to advance this benefit until HD becomes the sound quality standard for VoIP and eventually all telephony.”

Because iNum numbers can be dialed from PSTN phones as well as IP endpoints, Voxbone’s move enables conference calls with attendees on conventional phones, who will hear within the PSTN’s audio constraints, and others with high-definition IP endpoints, who will enjoy the richer sound of HD calling.
