Meet-me Conference is a potential security problem. If Meet-me Conference VDNs are assigned without access codes, hackers can tie up Meet-me Conference facilities, keeping others from conducting legitimate business and can potentially access the switch and use the switch to make unauthorized calls. Therefore, all Meet-me Conference VDNs must have access codes known to the users only on a need-to-know basis. You must also change the access codes on a regular basis to reduce the risk of unauthorized access.

If a user tries to change the access code of a Meet-me Conference and is unsuccessful, or if a user tries to access a Meet-me Conference and uses an invalid access code, a meet-me event is logged.
