Contract call reverts are caused by using incorrect parameters, lack of permission in the contract or a combination of these factors. In the case that contract calls revert, all input parameters and permissions should be checked.
In some cases a transaction fails to be submitted to the network. In the case that the transaction hash is returned as all zeros, adjust the gas limit and/or gas price. This is frequently caused by dust MRX that is in the sending address. Usually increasing the gas price from 5000 to 10000 will resolve this issue.
