We have a bunch of 8662 handsets that we purchased back in the days of the Inter Tel 7000. The kit has since been discontinued and we are left with the remaining handsets.
Is it possible to change the firmware on the handsets from the 7000 firmware to 5000 firmware?
If so instructions on how to do so would be very helpful.
