When user wants to hold or retrieve a call, the phone will send a reinvite to change the state of the call. The user will not be able to issue another reinvite (i.e. to undo the hold/retrieval operation) until phone has received an 200-OK. Turning this setting "on" will extend that time to until the phone will have send the ACK for the received 200-OK.
