On-One™
VOCAL’s On-One™ DSP technology provides a significant reduction in product cost and complexity. By running optimized DSP functions and application protocols together under VOCAL’s own lightweight network operating system (LANsEND), high density processing and scalability can be achieved.
For example, a DSP-based product might implement a full 4-channel ATA whereas a similar RISC processor-based product would rarely support more than a 2-channel configuration. For larger channel densities, the applications scale to the use of a full operating system such as embedded Linux. VOCAL’s reference designs are scalable to a customer’s specific product requirements. It is possible to integrate networking, signaling, data, and data processing on a single chip in order to provide a complete solution.
Reducing or eliminating the need for separate DSP components will result in lower BOM cost. Other benefits include improvements in power utilization, system, efficiency, future upgrade paths, and even overall product performance. Software development and integration is greatly simplified by providing a single lightweight, networked environment.
Concurrent SIP™
Concurrent SIP™ technology allows multiple SIP registrations with different SIP-based subscriptions and multiple VoIP service providers. Customers benefit from VOCAL’s robust SIP stack which interoperates seamlessly with most VoIP providers and products. This also makes it possible to customize ring tones, display options, and even dial plans based upon the particular VoIP provider.
Concurrent VoIP™
Concurrent VoIP™ dual stack capability allows both SIP and MGCP to be used seamlessly as per configured dial plan. This may work in tandem with Concurrent SIP™ in order to provide the most possible VoIP provider flexibility.
Our Software
VOCAL has repeatedly demonstrated its extensive development experience with critical aspects of real-time embedded systems. Our software maintains high QoS and low system latency even under network stress with packet delay and jitter while working within existing memory, MIPs, and power constraints on both custom and Commercial Off-the-Shelf (COTS) hardware. It is optimized to meet small memory footprint requirements, high QoS standards, maximizum performance, or a best-case balance between these often conflicting requirements.
VOCAL’s highly experienced engineers will work seamlessly with your staff to develop new technologies and integrate licensed components into your product. Our expertise with embedded systems and firmware integration means significant cost-savings, fast development times, and high quality products.
