I've been trying to get the auto answer feature to work properly on an F9600 ESNR ver. 12. The auto answer part works fine, but when the calling party hangs up the MLDT stays in speakerphone mode and returns dial tone. The user guide states that the phone should hang up by itself, but it doesn't. When I went to Fujitsu training a few years ago I seem to remember that the lab phones would hang up by themselves. Anybody have any ideas?
