no but iax makes it harder to do mitigation techniques.  This is becasue
media and signalling are on the same port.  Why I was asking about that
specifically.  

You cant rate limit packets very well since 10 calls from a given
endpoint will look the same on an IP level as 1 call, just a larger
volume, so if you do rate limit the audio quality, and potentially
signalling information will be impaired.
