ATA 186 is connected to a CIsco switch & hangs frequently. The distance between ATA & CIsco Switch is more than 70 m.
Is there any specification for supported distance between Cisco switch & ATA 186 ?
Maximum length for ethernet cable is 100 meters (328 feet). Doesn't sound like you're over the max. Have you tried upgrading the firmware? Using another ATA at the same location?
I even tried placing IP phone & another ATA 186 at that location but faced same problem. What can be the issue ?
