Features

This feature overview lists the Diva System Release software features. For information about Diva softIP for SIP features, see Dialogic® Diva® softIP for SIP Software.

Dialogic® Diva® Media Board-related features are listed under Diva Media Board features and in the Product Features section, starting with the Supported Interfaces topic.

The features list includes information about:

General features

The Diva System Release software offers the following features:

The new DMA interface adds virtual DMA channels providing an increased data transfer performance. This interface enables also the usage of SIPcontrol with the V-8PRI PCIe Media Board on all channels.

“CAPI show channels ISDN1#30” prints the call control status of the specific line

“CAPI show resources ISDN1#30” prints the media resources status of the specific line

Diva Media Board Features:

All Diva Media Boards with DSPs, except Dialogic® Diva® PRI/E1/T1-8 PCI and Dialogic® Diva® V-8PRI PCIe FS Media Boards, can be used as conventional TDM boards and/or as DSP Resource Boards for third party application scenarios that require DSPs, such as clear channel fax or clear channel modem but also for VoIP codecs for transcoding. The latter can be implemented by a CAPI or Dialogic® Diva® SDK application via so-called NULL PLCIs. Please contact Dialogic Customer Support for more information.

The Combined Board is named M-Board in the web interface.

    • With the Internal Call Transfer, an application can forward a call to another application. It is possible for application manufacturers and developers to detect the characteristic of a call (Fax, Voice, Modem, etc) and forward the call to another, compatible application. This is required if a solution is split into multiple single applications. This feature is especially relevant for application developers. For further documentation, contact the Dialogic Support team.

    • With the Call Transfer Emulation (ECT Emulation), an application can initiate a Call Transfer at a high level call control API (e.g., CAPI, Dialogic® Diva®  SDK, TAPI, etc.). The M-Board can emulate a regular Call Transfer behavior at the upper interface (Call Transfer result and disconnect towards the application) while the Diva Media Board bridges the two channels together, also known as tromboning. This helps if the switch does not support Call Transfer or if it is required to bridge a gap between the Call Transfer start and completion (board stays connected until the switch completes a Call Transfer). This feature can be configured on the Board Configuration page under ECT Emulation.

Note: Line Interconnect is not supported for Diva Media Boards grouped in an M-Board.

Fax and voice features

VoIP features

QSIG features

Note: For a complete list of supported protocol dialects, see Supported Switch Types.

Diva TTY driver

The Dialogic® Diva® ISDN serial driver provides access to analog, digital, fax (FAX CLASS 1 and FAX CLASS 2 with ECM, compression, and polling support), V.110, B-channel protocol detection, caller ID, and voice capabilities of the Dialogic® Diva® Media Boards by providing a standard serial driver interface. This allows for using Diva Media Boards in a variety of configurations:

The status of the exposed driver ports by the Diva TTY can be controlled using the Dialogic® Diva® TTY Management Interface Directory (Port Manager) of the driver, which is accessible using the WEB-based management interface browser or using the mantool command line utility. See Management Interface Access and Monitoring Utility for more information.

CAPI 2.0 support

The CAPI 2.0 (Common ISDN Application Programming Interface) driver allows CAPI-based applications to be used with Diva Media Boards and the Diva softIP Software. It also provides a mechanism for the development of customized applications enabling you to use the capabilities of ISDN. For full information on the CAPI interface specification, refer to the CAPI Association web site at http://www.capi.org.

Supplementary services supported by the Dialogic® Diva® CAPI 2.0 driver:

Note: The availability of supplementary services depends on your switch or PBX.

Dialogic® Diva® SDK support

The Diva SDK runtime is included for RPM-based and for DEB-based systems. It provides the Diva API and the Extended CAPI 2.0. The Diva API contains modules that can be used as basis for communication applications, such as fax and voice transfer or call control, and in the development of applications for these areas. The Extended CAPI 2.0 provides Dialogic-specific extensions for CAPI 2.0, which are fully CAPI 2.0 compatible, and thus can be used with CAPI 2.0

For more information, see the Dialogic® Diva® API Developer's Reference Guide available at:
