The problem with this approach, and with scrubbing centers more generally,
is that while the cure might be better than the disease it doesn't result
in usable VOIP.  Voice customers don't care if things are _better_ but
their MOS scores are still below 2.

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.

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.
