D2 Technologies (www.d2tech.com) demonstrated the latest version of its mCUE software, showing live VoIP and video calls over LTE in Las Vegas, including RCS calling using an IMS-based platform.
The mCUE 4G software is optimized for Android to deliver carrier-grade voice and video over smartphones, tablets, and other mobile devices. The software recently completed its first field deployment for a 4G mobile operator and demonstrated its VoLTE interoperability at the MultiService Forum’s testing event in Beijing and Dusseldorf.
Live demos in Vegas featured IMS-based connections over a Tier 1 carrier’s LTE network to make video calls between a tablet and smartphone. The demos were somewhat hampered by the general chaotic RF and communications environment during CES, requiring a couple of attempts before a successful connection was established.
mCUE 4G is a complete communications client with a fully embedded media engine including a complete VoIP DSP module with wideband codecs and optimized video framework integration supporting native hardware video acceleration. Features include IR.92 VoLTE and RCS/RCS-e standards compliant, VoIP and SMS/MMS over IP, IP video calling, and seamless call handover with SR/DR-VCC and CSFB.
