Issue fail2ban with asterisk

[2N3055]

Dear all:
fail2ban is protecting our asterisk software fairly well. However, fail2ban issues warning mails informing it has banned a certain IP when in fact, the supposed banned IP is neither banned nor appears in any server log. Have you ever seen what I am describing? Is there any solution to that behavior? Your comments will be highly appreciated.
