Dialogic® Diva® System Release for Linux

Diva for Envox

This is the easiest Communications Software we know of. It installs in minutes, it comes with many APIs, it supports TDM as well as IP, it is easy to support and it is freely downloadable.

The Dialogic® Diva® System Release 9.6LIN enables you to use Dialogic® Diva® Media Boards and/or Dialogic® Diva® softIP for SIP (a "virtual" VoIP/FoIP media board) with the Linux operating system. Even the most recent distributions as well as the latest kernels are supported. NOTE: Up to kernel 2.6.39 the install works completely automatically.

The Diva System Release 9.6LIN allows up to 8 Diva Media Boards (and more) to be installed on a computer running the Linux operating system distributions SuSE, Red Hat, Debian or other generic Linux distributions as 32 or 64 bit variants.  

The Diva System Release 9.6LIN fully supports all Linux communications and remote access service features, providing support for remote dial-up access for ISDN, V.90 analog, or GSM mobile phones. With support for the CAPI and the TTY interface (modem emulation), the System Release 9.5LIN SU2 uses Diva Media Boards (E1/T1/J1/PRI/BRI, Analog and IP) to create a flexible platform for Fax, Unified Messaging (Email, Voice Mail, SMS), IVR, Conferencing, POS, Monitoring, RAS, and many more applications.

The built-in Chan_capi driver allows to use all Diva Media Boards including Diva softIP for SIP with Asterisk®. This enables the Dialplan application to benefit from the large number of features provided by the Diva Media Board family. The documentation on Chan_capi and on Diva can be seen in the live demo below or after downloading and installing the Diva SR 9.6LIN.

System Release 9.6LIN enables a set of easy configuration and management tools for Diva media boards and Diva softIP for SIP. Remote configuration and management is available via the Dialogic® Diva® Web Configuration Wizard. This password-protected, web-based tool allows for remote parameter setting, tracing, troubleshooting, viewing statistics, etc. For more details and a live demonstration, click below.

Application Notes

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.

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.
