We have a Compact ICS that has a wierd problem. When an inbound call is received, the system will stop audibly ringing after 4 rings, but will continue to flash on the phones until picked up. The caller still hears ringing until answered. The telco provider is Comcast Cable. I checked the line on the 66-block before it its the phone system and my buttset will ring until I answer the call, which I think eliminates the telco provider ring voltage as an issue. We have replaced the analog trunk card and the issue continues. Any advise would be greatly appreciated. TIA.
