You can also specify the length of DTMF events that the gateway generates. For more information, see DTMF settings on page 119. Note: The factory sets the parameters for the Media_board and Resources keywords. Do not change these settings without contacting Dialogic Services and Support. Trunk settings Use the Trunk keyword to specify the trunks that the media board uses. - Page 117 Dialogic® Vision™ CX Video Gateway Administration ManualFine tuning the CX Video Gateway configuration Parameter Description media_board_num Logical board index of the media board containing the trunk, referring to a board previously declared with the Media_board keyword.
