I have mgetty working correctly on my Redhat 5.1 box. I had ringback enabled because I use my line for voice calls also. I worked fine for a while. Mgetty now answers all calls, so I had to disable it. What would cause ringback to stop working? Is there a file that is written to that should have been deleted? Maybe a file that is created that signals mgetty that the initial call has been received?
