about 80 persent of the time the single line extension will ring once and hangup. the customer only uses 2 of the extensions on the card and both do it. They had multiple phones and loud bells connected to each and I thought I had the problem resolved by eliminating most of the devices on each extension. The customer called back and said it is still doing it. Is it possible that the card is bad? I don't have a replacement card does anyone.
What happens if you take all devices of analoge extn and try to ring the extn then .
Beleive there is only certain amount of devices should be on each ctt if to many you would get ring trip
