vPort™GW VoLTE

VoLTE Gateway

Designed for flexibility and portability, vPort™GW VoLTE can execute on both RISC and CISC platforms under industry-leading operating systems. It has been optimized for ARM, MIPS, x86, PowerPC, and other processor architectures under the VxWorks, Nucleus, Linux and Android operating systems. vPort™GW VoLTE incorporates a state-of-the-art virtual DSP architecture, which implements voice DSP functions in software ("soft DSP") on a general purpose CPU core. The Voice over LTE (VoLTE) IMS SIP stack is fully IR.92 compliant. It also provides SMS over IP and many other rich supplemental services such as TIP/TIR, OIP/OIR, CFN/CFU. vPort™GW VoLTE has been tested and fielded with numerous commercial IMS core servers including ALU / NSN, Ericsson, Huawei, ZTE, Genband, Mavenir, and others.

vPort™GW V+

VoWiFi / WiFi Calling Terminal

D2 Technologies’ vPort™ GW solutions deliver high voice quality, efficient system implementation, and broad OS and IC support. With vPort™GW V+, OEMs and ODMs can quickly and cost-effectively develop a broad range of VoWiFi / WiFi Calling-enabled devices. It supports multiple VoWiFi services, such as ePDG tunneling, EAP-AKA / EAP-TLS authentication, and IMS-compliant SIP signalling. In addition, by implementing all voice DSP functions in software ( "SoftDSP") which operates on a wide range of general purpose CPU cores, vPort™GW V+ lowers system costs by eliminating hardware DSP, and provides portability across a wide range of OS (Linux, VxWorks, Threadx, and more) and IC (ARM, MIPS, x86, PowerPC and more) platforms. Portablity of vPort™GW to different customer hardware and software platform is accomplished with a highly modular architecture, with multiple abstract software layer,s. Higher layers allow easy customization, and lower layers are designed to minimize latency.
