We just got all new 6408 sets (from 8400 series)
WE have had about 5 phones that suddenly started screeching when the user's picked up their handsets. Some of these when I unplug them and use them else where the screech goes away. any ideas?
Also in a past thread:
thread690-655595 it states that a newer set will give the serial number when you stat station..what is the difference between the sets that give it and those that don't. Our's do not give it, which makes me think they are older?..
Thanks!
