Interesting stuff!
Just to clarify, I was not accusing you. I was being a little tongue-
in-cheek. :)

Hi Alex,
NO that definitely NOT the motive!!!
I do write my master's thesis about SPIT prevention (SPAM over
Internet Telephony) and I try to implement several ideas in kamailio
to detect SIP-URI's that try to "spit".
So don't worry...I won't use your help to do illegal stuff! Hope
that's clarified.
Amongst other ideas I try to implement a functionality that matches
a suspicios caller's identity on a list in the database.
Afterwards the caller is either rejected or delayed, depending on
his reputation that I compute before using other ideas.
I want to delay some of these suspicios calls instead of rejecting
them completly as rejecting a call is really hard.
Further I expect automatically initiated calls to have a timeout. If
the "spitting" party won't get an answer fast enough it might walk
on and try another IP.
The idea is indeed adapted from the "e-mail world".
Regards,
Nicolas

Betreff: Re: [SR-Users] provoke delay?
I get this question a lot privately from people who want to play
games
to pad out the billable time in a call by sitting on it for a while
before passing it up to their vendors/upstreams.
If by chance that is the real motive, don't do it. :-) It's far
more
trouble than it's worth.
