Richardson, TX – May 31, 2012. Mavenir Systems, leading innovator of converged IP Voice, Video and Messaging solutions for wireless carriers and Imagination Technologies, a leading multimedia and communications technologies company, today announced completion of IR.92-compliant VoLTE interoperability testing (IOT) of Imagination’s HelloSoftV.VoIP mobile device client with Mavenir’s IMS- based Converged Telephony Application Server (CTAS).

Imagination’s HelloSoftV.VoIP SDKs enable the most comprehensive multi-platform mobile device solutions in the world for delivering the full range of two-way, real-time communications, including Voice over LTE (VoLTE), Voice Call Continuity (VCC), Video and Voice over IP (V.VoIP), SMS over IP and Rich Communication Services (RCS). Imagination’s VoLTE solution is fully standards compliant with 3GPP, Voice over LTE and IR.92 specifications, and incorporates award-winning multi-platform HelloSoft VoIP technology that features Acoustic Echo Cancellation (AEC) and Noise Cancellation (NC) to produce superior voice quality on 4G mobile devices.

Mavenir’s comprehensive product portfolio includes a number of value-added servers, such as the Rich Messaging Server (RMS), the Presence and List Server (PRS), and the MMTel-compliant CTAS, that enable mobile operators to deploy new, innovative services to meet the evolving communication needs of their users.

Terry McCabe, chief technology officer, Mavenir Systems, says, “We have responded to carriers’ needs for rapid commercial deployment of voice and messaging over LTE, and are very pleased to complete VoLTE-interoperability testing on a range of leading OEM devices. Working closely and cooperatively with Imagination Technologies, we have shown that multi-vendor interworking is a key element of the successful roll-out of operator services in the LTE environment. Our ability to partner and innovate in the OEM market is proven and valued by many customers now selecting Mavenir with confidence as part of an overall network transformation strategy.”

Says Allan Johnson, general manager, HelloSoftV.VoIP at Imagination Technologies, “We are very pleased to complete IR.92-compliant VoLTE interoperability testing (IOT) with Mavenir’s Converged Telephony Application Server for deployment later this year. Carrier network interoperability is very complex, making the best feature and voice performance difficult to achieve, especially across the diverse range of mobile devices and chipset architectures. We created an SDK that is easy for OEM and ODM manufacturers to integrate, portable across all major operating systems, and highly optimized across common 4G processor and modem architectures. Imagination understands the mobile space very well: more than 750 million mobile and embedded devices from every major brand have already shipped with at least one of our multimedia IP technologies inside. We’re now looking forward to working with Mavenir’s customers to deliver HelloSoft solutions.”
