At the HD Communications Summit, Wyde Voice announced HD SoftBridge, its HD audio and web conferencing bridge technology in software form. The new tech eliminates the need for DSP cards so audio conference providers can use off-the-shelf hardware to setup conferencing bridges that scale from 2 to 10,000 concurrent user ports with multiple cards/blades.
HD SoftBridge supports wide variety of codecs including G.722, G.722.1, G.722.2, iSAC, and some softphones. Mike Eastman, Wyde Voice VP of Global Sales, said the company wants to avoid transcoding and support native codecs as much as possible. Running on a blade server, the smallest version of the conferencing bridge (single blade) supports 1,000 concurrent users while a multi-blade configuration can support up to 10,000 users.
Eastman took care to highlight the various technologies used to build HD SoftBridge, including AudioCodes and GIPS. It also incorporates Digium Asterisk to support its IVR functionality and supports a wide range of softphones such as Gizmo5, CounterPath, and Skype; plenty of HD IP handsets are supported and have been tested as well, including Polycom’s family of phones.
Multiple servers can be setup to support different geographic regions, with a single voice stream connecting a conference per geography. A distributed architecture obviously has certain advantages when it comes to supporting long distance calls.
Interesting features of the bridge include the all-important web services API, support for legacy call flows via AEL, and real-time I/F in SIP so an administrator can see conference participants and other details. Wyde Voice’s “sister” company Freeconferencecallhd.com has used the API to build its service; one feature available is the real-time playback of recorded calls within a live conference call.
