guys im having this strange issue where everytime i plug in a voip phone to my 3550 the switch disconnects another voip phone, does anyone know why this could be?
then to fix the disconnected phone (7940) i need to power off the phone 5-10 minutes then power it on again. but the strange thing is, once i have to do that to fix the phone and connect the phone back to the switch, the port link is up, but no macs are seen on that port.
