Vocallo MGW is a multi-core processor for voice and video over IP. Vocallo is the industry’s most versatile DSP platform for voice and video over IP applications. Vocallo allows you to reduce your system cost by delivering the lowest power per channel. Vocallo’s new business model offers optimal pricing scalability for media gateways in enterprise and converged fixed-mobile carrier networks.
Vocallo offers a complete hardware and software solution for media gateways. The software package includes voice processing with support for packet-based wideband audio as well as video processing for real-time communications. All of this is delivered in a 15 core, ultra low power DSP, based on Octasic's Opus core architecture.
Vocallo offers a complete suite of features and focuses on reduced system cost, low power, and high density solutions making it the industry leader.
Designed for Wideband
Vocallo MGW is designed for wideband from the ground up. In addition to supporting voice codecs like G.722 and AMR-WB, all other required features are available for wideband such as conferencing, tone detection and a wideband-enabled TDM bus.
Echo Cancellation and VQE
Solutions for Echo Cancellation and Voice Quality Enhancement (VQE) are highly complex and hard to obtain. Thirty million lines in networks worldwide rely on Octasic's carrier-recognized EC and VQE solutions. They surpass the latest G.168 standard tests to deliver leading voice quality and a transparent user experience.
Extremely Low Latency
Vocallo is designed to process media connections with minimum latency. Its packet-based software architecture avoids flow-pinning and fixed scheduling. Media channels are flexibly scheduled, adapting to network packet delay distributions. This reduces the required scheduling delay by orders of magnitude for both packet-to-packet and packet-to-TDM flow.
Advanced Video Applications
Vocallo MGW supports applications such as 3G-324M, Interactive Voice Video Response (IVVR), video-conferencing and video-enabled services with capabilities such as real-time video transcoding, video transrating and conferencing.
Vocallo MGW API integrates H.263, MPEG-4 and H.264 codecs and several real-time video processing functions. Vocallo MGW also provides sophisticated mixing capabilities. Up to 16 layers can be assembled in real-time to create IVVR menus, Picture-in-Picture (PIP) or branded video streams. Each layer can be a video stream, an image, color box, or text. When applying the layer, the user can dynamically control the size, position, luma key and opacity.
Robust Video Solution for Today's Networks
Vocallo MGW video codecs have been designed to address the unique challenges of delivering quality video on error-prone and bandwidth-constrained wireless networks. All codecs include error resilience and concealment techniques to minimize the effects of packet loss. The integration of voice and video on the same device allows Vocallo MGW to maintain perfect A/V synchronization. The bit rate controller developed by Octasic optimizes the trade-off between quality and bit rate. This provides the best possible image quality on bandwidth-constrained links such as those found in mobile networks. Vocallo MGW can therefore overcome situations such as network congestion while ensuring fluid playback.

Telecom Evaluation Platform (TEP)
The Vocallo MGW TEP is available as a fully functional gateway appliance. Housed in a standalone 1U sized metal enclosure it allows users to quickly evaluate quality, compliance and interoperability of the Vocallo MGW solution.
Designed for testing within a laboratory environment, the TEP is in essence a complete gateway-in-a-box. By means of the intuitive web-based control panel, the user is able to easily configure the system to inter-operate with off-the-shelf telecom test equipment. Evaluation tests can be up and running in a matter of minutes, without having to develop test scripts or test hardware.
Telecom Evaluation Board (TEB)
The Vocallo MGW TEB allows designers to quickly and effectively evaluate Octasic’s Vocallo MGW solution. Providing a range of standard telecommunication interfaces, the board easily connects to either the network or to standard telecom test equipment. With this TEB, designers can begin prototyping with the Vocallo API to evaluate device functionality and performance.
Octasic partnered with RADVISION to enhance delivery of Octasic’s complete media gateway solution for the fast-growing mobile video market. The inclusion of RADVISION’s 3G-324M stacks allows Octasic to meet current needs for 3G handset users, and further increases the spectrum of mobile video services that Vocallo MGW solution supports.
