Narrative:
Received call from [maintenance] stating that they had received a satcom call from aircraft X regarding their left idg (integrated drive generator) not working. Crew spoke to [maintenance] directly; I was not involved in the conversation; though I should have been. This flight was still in an ETOPS area of operation; and idg problems have an ETOPS impact and if the crew was required to start the APU; would have a fuel impact. Because [the crew] spoke to [maintenance] without dispatch on the line; no position report was obtained; either. After the fact; [I] figured out that a satcom call which came in earlier at another desk was the airborne aircraft X. However; at that time; there was another flight of a different flight date on the ground and it was thought that was the flight calling; not the one in the air. In any case; the airborne aircraft X crew apparently was offered to be transferred to their dispatcher (which would have been me) but insisted on being transferred directly to [maintenance] instead. I didn't realize what had transpired until after [maintenance] contacted me.not sure what happened or why crew did not involve dispatch in their communication with maintenance. Fortunately; there was no operational impact and flight continued uneventfully to ZZZ. Remind crews that when they have an issue enroute; unless an immediate emergency or something else that doesn't permit; they need to keep their dispatcher in the loop and involved in order to ensure proper operational control is maintained.
