Unlocking Vonage ATA 186
In the process of investigating a Cisco ATA 186 that was locked by
Vonage, I found that you can still unlock the device yourself. But
there's a catch.
The device's design has a great plus: a DIP32 *socketed* SST28SF040A
flash chip. I found an 8 digit unlock code at 0x03FA71-0x03FA78. I do
not know if that is a standard location.
If you have the equipment, you're in luck. But IMHO, the $15 fee is
more than reasonable .. and certainly less than what it would cost to
get a device to read/write these flash...
