Anyone using SecureLogix and can comment on their ability to ?Prevent service abuse and malicious or unwanted voice traffic to lower expenses and boost your security and compliance efforts. ? http://www.securelogix.com/Telephony-Denial-Of-Service/index.htm It sounds like it isn?t just an SBC-type prevention of SIPVicious-style attacks, but also TDM blocking based on ? policy fields? call type; absence or blocking of caller ID, call source and destination numbers; call direction; time of call; call length; and certain VoIP call attributes, such as excessive media rate? I understand this can sound appealing, but having had to deal with a few TDOS attacks, I am not sure how well does this would work in practice. Anyone able to comment?
