Generally, that is not true. Mountain lions have long been classed as a big game animal in Idaho and electronic calls are not legal in hunting big game animals except (you knew this was not going to be perfectly simple) in three units. It is permitted to use electronic calls to hunt mountain lions in Units 12, 41 and 42 where we have been experimenting with increasing the take on lions to see if other big game animal populations will expand. Electronic calls are fairly popular with coyote and bobcat hunters in Idaho and are perfectly legal to use for hunting them. Coyotes may be taken year round but bobcat hunting is regulated, so see the current furbearer rules in the upland game and furbearer booklet.
