Programmer
I have a compact that has 4 centrex lines connected to it. The lines are set to appear and ring in programming, but they make a slight chirp occasionally and flash on and off on sets; however, they stopped ringing properly. I placed a butt set on rj21 and called and it rings in same way, weird short. Callers hear ringing as normal, and if you see flash and pick up conversation is normal. Any suggestions?
