Voxbone announces that its geographically-independent number service, iNum, now supports HD calling between dozens of VoIP networks and Skype, the global leader in Internet communications.

Greatly expanding availability of emerging HD voice technology, Voxbone will transcode, or translate, between Skype's super-wideband SILK codec and the widely deployed HD codec, G.722, Voxbone announced at eComm Europe 2009.

Prefaced with the ITU-assigned 883 code, iNum numbers refer to the Internet as the 44 country code refers to the U.K. Calls to iNum numbers are routed first to Voxbone, which delivers them to the appropriate service provider over IP.

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.
