Hi Gary,
As i seen in sh power inline o/p few alcatel IP phones are class 0 while others class 2. Is this creating the problem ?
Also as per my observation all phones are working but suddenly after an hour or day few phones gets power-off while others are working. So after restarting the switch, all IP Phones starts working.
O/P of " sh power inline" is below
