It is far worse when you have multiple phones behind the same public address (i.e. NAT).    If any one of the phones has a bad password and the IP gets blocked by fail2ban, then all phones at that site would be blocked.

One of the dangers with fail2ban - at least in its default configuration
- is that a legitimate SIP phone with an incorrect password can quite easily send dozens of registration attempts in a couple of minutes, thus blocking that IP.
