Well, one other thing you could try is to create a file
/etc/udev/device.d/15-isdninfo.rules with a line:

KERNEL=="isdninfo", NAME="%k", GROUP="dialout", MODE="0660",
OPTIONS="last_rule"

With the OPTIONS="last_rule" at the end, nothing should overwrite
the permissions. (Console.prems will once someone logs in at the
console if you still have your added rule.) If it does not work,
then chances are something outside of udev is changing the
permissions. But I have no idea what.
