I have this problem for 2 days now and I don't know how to solve it. When my home phone get an incoming call, it rings once and half rings the second time. After that the incoming call will get a busy tone. Now I just have to rush to get to the phone after the first ring or else it will get disconnected. Anyone knows how to fix this problem. Also, after finish receiving phone calls my internet get disconnected for a while. It always happens after a phone call ends.
