FYI, UTRS (Unwanted Traffic Removal Service https://team-cymru.com/community-services/utrs/) from Team Cymru is a free service where you can send a blackhole advertisement (sacrificing the one IP that’s under attack to save the rest of the network) and they will propagate that via BGP to hundreds of other ASNs which will then blackhole traffic to that IP.  This can drastically reduce the amount of DDoS traffic that is received by the victim network.

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.

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.
