This attribute defines whether the bearer continuity test for a connection will be performed at the time of call setup or not. When the vismBearerContinuityTest is enabled, the terminating media Gateway initiates a NSE/Type 3 packet towards the originating gateway and starts a timer defined by vismBearerContinuityTimer. The originating gateway, on receipt of co3, responds by sending a co4 to the terminating end. If the terminating gateway doesn't receive co4 NSE/Type 3 packet with in the time defined by co4 timer, it initiates a GW-initiated DLCX to the call agent which in turn deletes the connection. The value in this object will be utilized when the call agent does not specify this.
