Application Notes

Brochure

  • Business communication solution and service providers can increase their ability to deliver more productivity and efficiency for their customers when they build on Dialogic® products.

Data Sheet

  • The Dialogic® Diva® PRI Media Boards are building blocks for enabling speech and Voice over Internet Protocol (VoIP) applications. The Diva PRI Media Boards are based on the latest PCI and PCI Express standards, and provides connectivity to the telephony network via ISDN PRI, E1 or T1 interfaces.

Technology Brief

  • The Dialogic® Diva® Software Development Kit (Diva SDK) offers a powerful set of Application Programming Interfaces (APIs) that can be used for implementing telephony applications, that is, applications that accept and process phone calls.
  • To connect to the PSTN, Asterisk systems require a network interface board or a media gateway. Because most Dialogic® Diva® Media Boards have powerful Digital Signal Processors (DSPs) onboard and can move processor-intensive, low-level tasks to these DSPs, significant reductions in server CPU load are possible. Such reductions can positively impact overall performance and scalability in systems such as those using Asterisk software.

White Paper

  • Advanced speech-enabled applications and systems are changing the way in which we interact with all types of businesses. Moving beyond a few showcase situations, speech technologies are being used in many new and exciting applications, such as voice portals, call center self-service, directory assistance, and voice-activated dialing. With speech applications customers can obtain information or direct transactions using the most intutitive interface - speech. When used in conjunction with IVR and self service applications speech recognition technology greatly reduces the cost of staffing a call center operation, while reducing call durations and call handling time and increasing call completion rates.
  • Interactive Voice Response (IVR) is probably one of the most widely used technologies today. IVR is one of the most useful and cost-effective technologies around, with applications encompassing movie schedules, bank tranfers, reserving plane tickets, and refilling prescriptions.
  • This white paper discusses what ISVs and system integrators should consider in a media board for IVR systems, and why they must carefully select the right board for their needs.
