[Serusers] voip charging by ISP's

[Vitaly Nikolaev]

I believe It is unlawful act and there must be some regulation, I am not
talking here that it will become known very well and this provider will
lost some customers... and some other provider will claim that they voip
friendly and get some more customer on it :-)

Well, i think the ISP may care if they are also providing similar
bussiness. They won't probably be able to charge neither the voip user
or voip provider, but they can do some harm. Identifying the rtp streams
and sip signalling is not sooo difficult ... then, block a few messages,
add delay and jitter to the rtp (or udp in general ...) and you've got a
bad service, aparently coming from the voip provider. 

There is software to detect and do all the above (one was presented in
VON this fall) ... 

There was an article in IEEE Spectrum (sept, october, nov ... can't
remember).

 

And all the tricks Nils mentions ... hey, maybe the advanced user, but
my mom, no way! And then you need software that supports all those
tricks ... that is even further away. In this sense, i think carriers
have the winning side ...

I think the ISP should not care what it is transporting. The snail mail
also
does not look into what they are devlivering to charge you differently 
(except express delivery but thats another story).

As soon as an ISP starts to look into the traffic from the user, the
users
will invent uncounted ways of fooling the ISP (use non-standard ports;
use
standard ports for the "wrong" service; use proxies; encrypt the
traffic; and 
finally combine all this). All I can say to the ISP: happy debugging!
And in the end I would be interested in how a court would judge about
the
outcoming bills (who has to prove what?) :-)
