Narrative:

Message was received via ACARS that ECAM hydraulic 'G' system leak. Request was made of pressure and quantity. 2950 was pressure sent; never received quantity answer. With pressure barely in amber range and hearing no answer about quantity; I didn't ask if crew wanted equipment called. After arrival in ZZZ; I noticed a lengthy taxi-in time. Upon calling ZZZ; I was told of hydraulic failure which forced aircraft to be towed to the gate. I received no phone call from the crew about this incident.
