Narrative:

Air carrier X attempted to contact my sector (sector 58) several times before returning to previous controller's frequency. That controller then alerted me to the situation. I then monitored my vscs equipment to know when an incoming transmission was occurring by observing the frequency receive indicator lights 'twinkle.' this frequency -- 128.15 -- has had this problem as an ongoing issue for several months now. I then made contact with the pilot.
