I have a customer with a SV8100 with about 200 IP phones on it and there are 2 phones that continuously freeze up...the display is fine and phone looks as if its working but there is no dial tone and it can be called and rings once and goes to vm...if the phone is unplugged and plugged back in it works for a little while again.
The phone itself has been replaced,the jack and cable have been replaced,it has been moved to a new port on the POE and also delted completely and rebuilt.
Still these two phones lock up constantly.
Anyone have any ideas??
