Just to make this point. These are ISPs blocking VoIP traffic which they
can (http://www.fcc.gov/cgb/internet.html).
However you can just opt to NOT use their DSL services... some of the
larger DSL providers won't do this for tons of reasons, mainly because the
larger Telcos like Qwest, MCI, are providing VoIP wholesale services to
ISPs, and CLECS.
Lets say I start a company like vonage, right where I want to provide VoIP
services to Colorado consumers, and I decide to purchase wholesale VoIP
services from Qwest since I think I can send them 1000s of minutes worth
of traffic per month...
Then you have a home Qwest DSL user who is using my VoIP services, they
are #1 paying Qwest for DSL, then this VoIP traffic travels over the
internet to my PBX, then I send this VoIP traffic back to Qwest for
termination (ops they are getting paid again), I don't see Qwest just
shotting them self in the foot like that...
I think it will be a bad business decision for ISPs to start blocking VoIP
traffic...since it's easy to switch ISPs...
Finally, we sould all come up with a VPN (IPsec) Tunnel solution for VOIP,
this would NOT be vulnerable to this type of jitter injection technique,
however would require much more bandwidth.

An interesting article on carriers blocking VoIP and products that allow
VoIP to go through but degrade performance to the point its unusable.
This can affect both users in that they cant connect and providers in
that people say they have really poor quality when its not actually the
providers fault.
I found it interesting and thought others might as well.

I think this article actually points the finger at some who are already
engaged in this practice.

If this becomes widespread we can all forget about low cost phone calls over
the net.
