wcf服务端如何处理多个Action为空的操作？

Question

现有固定协议的webService，要开发一个相应的wcf服务，客户端是固定的，发送的SoapHeader中不包含Action信息，而服务端OperationContractAttribute中只能有一个Action=""，如果OperationContract中不设置Action，则会报错
{"The message with Action '' cannot be processed at the

receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of

either a contract mismatch (mismatched Actions between sender and receiver) or a

binding/security mismatch between the sender and the receiver. Check that sender and receiver

have the same contract and the same binding (including security requirements, e.g. Message,

Transport, None)."}

如果设置其中一个Action=""再调用这个函数，能正常运行。
但这个Service中有多个函数，服务器端要如何定义才能识别空的Action？
在具体实现上加了[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]，没起作用
