All phones do this or just a single 3905?  You could try to drop the firmware down and see if that makes a difference then re-upgrade.  Is this on a CME or CUCM?

I have different type of telephone but Is working correctly, I try do this this before but is not work too,

it's is CME..

 

please help me
