If you intend to submit a proposal to a specific call you have to consult "Call Fiche", "Work Programme" and "Guide for Applicants" which you will find in the "Information Package" of the specific call for proposal, (e.g. FP7-HEALTH-2007-A).
Look out for topics starting like this: e.g. HEALTH-2007-1.1-1, NMP-2007-1.1-3
