CallVine Delivers New iPhone Voice Conferencing App

iPhone users can now get high-definition audio conferencing and call control with Callvine’s new free HD Voice Conferencing app and service.

The Austin-based service provider's app delivers HD Voice over WiFi together with comprehensive business-class features based on TurboBridge’s conferencing platform. Users can host and synchronize calls, manage conferences through a live dashboard, and create and manage groups for both calling and group texting.

"With the increased use of mobile phones on conference calls, sound quality has truly taken a beating, making many calls unintelligible and inefficient," said Rudy Prince, Callvine’s CEO and founder, in a statement. "Now wherever there is good quality WiFi, iPhone users can conference with natural and vibrant sound, conveying more of the subtleties of the human voice. Within buildings and homes, WiFi connections also avoid the annoyance of dropped calls while eliminating the use of mobile minutes and international dialing charges."

"Today, high-definition audio conferencing is enjoyed in many conference rooms through VoIP conference phones," Prince continued. "Utilizing TurboBridge's HD conferencing technology—already being used by communications industry leaders such as Broadvox and LogMeIn—we're able to bring unparalleled HD audio quality, live conference controls, and free HD recordings to the iPhone. There's also less wasted time by synchronizing meeting start times with push alerts while the conference host can further manage call quality by instantly muting noisy connections from the app’s dashboard."

Steve Davis, senior vice president of technology and operations at HomeAway, is already a fan. "At HomeAway, we've always found high-definition audio makes our meetings much more productive and efficient, and we became an early customer of TurboBridge. With Callvine bringing this technology and HD Voice to the iPhone, the superior sound quality is no longer limited to conference rooms but can be used from anywhere," he said in a statement.

Ken Ford, former CEO of Global Conference Partners, parent of FreeConference.com, states, "By bringing mobility and HD Voice to iPhones, Callvine represents the next generation of free conferencing. While there are many iPhone business apps available, Callvine fills a unique void in the conferencing market through its ease of use, the combination of clear HD Voice with traditional telephone dial-ins, and live call controls."

To support its HD Voice services, Callvine implemented the industry-standard G722.1 wideband codec licensed from Polycom, which doubles the frequency range the ear receives. As Polycom describes HD Voice, it is similar to "switching from AM radio to CD-quality audio." Callvine's service also supports HD Voice from conference phones, tying together high-definition audio from iPhones to conference rooms, by connecting VoIP phones to @sip.callvine.com.

The Callvine app and service is free for up to 10 participants on a conference call and up to four hours of conferencing each month. Group texting and creating and managing groups is always free and simplified through the use of the iPhone's Messages app, keeping all texts and replies in one location. In-App upgrades will be offered later this quarter for increased numbers of conference participants and additional usage.
