The ResponseTimeMediator is called when invoke the service and when receive the response, so i generate a timestamp in each step but i face a problems to find a call identifier to match the entry call with the response call.If you add a property to the "incoming" Synapse message context in your custom mediator, the corresponding response Synapse message context should have the same property. (e.g. Sample 51 <http://synapse.apache.org/Synapse_Samples.html#Sample51>)
