+The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is an
+architectural framework for delivering IP multimedia services.
+
+vIMS has been integrated in Functest to demonstrate the capability to deploy a
+relatively complex NFV scenario on the OPNFV platform. The deployment of a
+complete functional VNF allows the test of most of the essential functions
+needed for a NFV platform.
+
+The goal of this test suite consists of:
+
+* deploy a Clearwater vIMS (IP Multimedia Subsystem) VNF using
+  OpenStack Heat orchestrator based on a HOT template defined in `[17]`_
+* run suite of signaling tests on top of this VNF
