D2 Technologies (News - Alert), a specialist in embedded IP communications software platforms, announced it is participating in the Voice over LTE (VoLTE) Interoperability Testing Event, organized by the MultiService Forum (News - Alert) (MSF) and now underway in Beijing, China and Dusseldorf, Germany.

The company is offering mCUE, a converged 4G mobile communications client for VoLTE and RCS video calling applications, in the interoperability event hosted at the China Mobile (News - Alert) Research Institute Laboratory in Beijing.

mCUE, according to D2, is a complete IP video calling solution offering a number of benefits to OEMs, ODMs and service providers. It supports industry standard voice and video CODECs and offers wideband CODECs for high-definition voice and an industry-leading Acoustic Echo Canceller (AEC).

It also supports Apple iOS for the iPhone and iPad.

Also, D2’s vPort embedded IP Multimedia Subsystem (News - Alert) (IMS) Voice over Internet Protocol (VoIP) software platform is participating in the test at the Vodafone Test and Innovation Centre in Dusseldorf.

"With D2 joining more than 25 companies participating in the interoperability event, we are confident the testing scenarios will show that VoLTE is ready for deployment in 4G mobile networks, realizing the vision of IMS rich communication services," said Doug Makishima, chief operating officer for D2 Technologies, in a statement.

The VoLTE Interoperability Testing Event is supported by GSMA, an industry association dedicated to uphold the interests of mobile operators and more than 200 companies in the broader mobile ecosystem worldwide.

The goal of VoLTE Interoperability Testing Event is to validate the GSMA's technical recommendations for IMS-based VoLTE and to establish best practices for Long Term Evolution (LTE) deployment strategies. Test scenarios include VoLTE basic interoperability, roaming and interconnection.

The event is scheduled to run through Sept. 30, 2011.
