UCM630X Series User Manual
Version 1.0.2.25
Fail2ban
Fail2Ban feature on the UCM630X provides intrusion detection and prevention for authentication errors in SIP
REGISTER, INVITE and SUBSCRIBE. Once the entry is detected within "Max Retry Duration", the UCM630X
will act to forbid the host for certain period as defined in "Banned Duration". This feature helps prevent SIP brute
force attacks to the PBX system.
