This attribute describes whether notification of RSIP cancel graceful is enabled/disabled per protocol per MGC group configured. The Restart in Progress command with the restart method of cancel graceful indicates that the gateway is canceling a previously issued 'graceful' restart in progress command. The endpoints are still in service. When the object is set to 'sendCancelGraceful', the gateway will send the Restart in Progress command with the restart method of cancel graceful indicating that it is canceling the previously sent 'graceful' Restart in Progress command. By default, the object is set to 'sendCancelGraceful' for MGCP 1.0 and 'notSendCancelGraceful' for all other protocols. This object has no relevance when the protocol is SRCP.
