[VOIPSEC] Anti-DDoS products for VoIP

[Seim Eirik (UmoeIKT)]

The usual suspects in DDoS protection (rate-limiting, qos, randomly dropping sessions, etc) will also help VoIP, but against a carefully designed attack I have serious doubts about the voice quality. By all means, a product list could be interesting, but what I'd rather prefer is experiences from people who has recovered a VoIP service from an ongoing DoS attack (or failed in doing so), and what methods they used. Router configurations can be just as interesting as a fancy VoIP-branded security appliance...

As for specific products, how about a few traditional phone lines in reserve?

Hello list,

I am trying to compile a list of the leading anti-DDOS attack products
for VOIP and thought maybe this is the best place to ask. Has anyone
looked into DDoS protection for VoIP and what are the leading products
in this area? You can email me privately or to this list.

Many thanks,
