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.

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.
