Defending against Attacks
VCS sometimes may receive calls from unknown caller, and the calls may be unable to answer. For the
communication security, VCS supports the features of defending against attacks. You can configure the
abnormal call answering feature to handle the abnormal SIP incoming call or configure the safe mode call
feature to verify the H.323 incoming call.

Configuring Abnormal Call Answering
When the destination address of the incoming SIP call does not match the local address, the call is
considered to be an abnormal call. You can deal with them by setting them as the abnormal SIP incoming
call. You can reject the abnormal SIP incoming call, or answer it by using IP address or SIP account
randomly. This feature is not applicable to VP59.
