The Bearer Capabilities are part of the Q.931 SETUP messages and define the characteristics of a call. The Bearer Capability parameter used by the calling party specifies the B-Channel that is being requested. The Bearer Capabilities Override pane will configure the IMG to either pass-through (ignore) the bearer capability or change it to a pre-selected parameter from drop down menu.
