Just double checked our QRH and everything that requires memory items has a 7700 change as part of the follow up actions (which would be before we would be ready to speak to you) and also at the end of the check lists which require an immediate return, inform ATC.
I don't know what other operators are like (but it has been the same for all the ones I have worked for, its the OEM emergency checklist) but I am presuming JAR aircraft at least will already have the when to talk to ATC plugged into the flow of of the emergency checklist if required.
