VoIP has been around for 10 years. That's some infancy :)  The point is 
that a holistic (or any) security framework was never a consideration when 
formulating some VoIP protocols which makes securing them after the fact 
much much more difficult.

It is very possible to create holistic interoperable approach for 
authentication and encryption (that goes most of the way) just they are 
much more difficult to do in SIP.

They also can also natively work behind NATs but that is a whole different 
thread :)

I guess the point of my rant (apart from livening up the list) is that we 
should not cloud or limit our expectations on VoIP security because of what 
we are using now but rather expect and demand VoIP security to do what we 
NEED in the future.  If we break things so be it, if we have to turn the 
world on its head then lets do that too.

10 years in a long time to be crawling so lets stand up and start walking.....
