Yes there are. I was about to message Steve about the correction. Corero and path.net are options. There are others.

It looks like Security Now covered this yesterday. They claimed that, "There  is  currently  no  provider of  large  pipe  VoIP  protocol  DDoS  protection."

Are any of the cloud DDoS mitigation services offering a service like this.

Subject: VoIP Provider DDoSes

As many may know, a particular VoIP supplier is suffering a DDoS. https://twitter.com/voipms

Are your garden variety DDoS mitigation platforms or services equipped to handle DDoSes of VoIP services? What nuances does one have to be cognizant of? A WAF doesn't mean much to SIP, IAX2, RTP, etc.
