This is an optional flag, which defines if the Radiator instance can act as a connection initiator. It is not set by default.

Initiator must be set if Radiator instance has to act as an initiator and create a connection to the Diameter peer defined by this <DiaPeerDef>. If Initiator is not set, the Radiator instance does not initiate connections but other instances, such as ePDG, must act as a initiator.
