I'm having a major problem at one of my branch offices with "Phantom Rings" on their asterisk-based phone system. The system was originally built using 2 X100P cards and was recently upgraded to a Rhino R4FXO-EC card. The upgrade severely increased the frequency of the phantom rings. I've read everything I can find on-line about automatic testing and noise on the line and have made several calls to Verizon with no solution to the problem. I know the telco switch that is feeding my analog lines is an old switch and can't even do CallerID with 2 lines in a rollover configuration. Audio quality on the line is perfect during voice calls. No static or other noise. I've asked for disconnect supervision to be added to the line, but It doesn't look like it's there. The line still seems to keep the channel open long after the far end hangs up.
Has anyone else ever seen this problem or have any ideas how to eliminate it?
