1.54 Conference Bridging on Dialogic
®
DI Boards
With the Service Update, the ability to bridge conference resources across Dialogic
®
DI
Boards is now supported. This feature is applicable to the following boards:
• Dialogic
®
DI0408LSAR2 Switching Boards
• Dialogic
®
DISI16R2, DISI24R2, and DISI32R2 Switching Boards
1.54.1 Feature Description
Conference bridging allows the parties from separate conferences to speak with and/or
listen to one another. Conference bridging can be used to effectively expand a conference
beyond the maximum size allowed by your particular configuration.
The following table shows the conference densities for DI Boards with bridging and
without bridging. Note that the creation of a conference bridge consumes a conference
resource on each end of the bridge. For example, bridging of two 5-party conferences
consumes a total of 12 conference resources. For this reason, the maximum number of
parties per board is reduced by at least one if bridging is used.
On DI Boards, bridging is supported via the Dialogic
®
Audio Conferencing (DCB) API. The
dcb_CreateBridge( ) function establishes a conference bridge, and the

Values in this column are for two boards being used with a single bridge (i.e., two conferences bridged together). The
maximum parties per board remains unchanged, and the new density is achieved by creating a separate conference on each
board and then bridging the two conferences.
Larger conferences can be created by bridging more than two conferences using a star configuration. See the Dialogic
®
Audio Conferencing API Programming Guide for further information.
