[OpenSIPS-Users] Generate CANCEL on 180

[Johan De Clercq]

Certain providers do this all the time : they bill faulty numbers

So they give 180 followed by instant 200 and then they play : "the number
that you tried to reach ....".

Actually, Antonis, you should try a few of those numbers manually, I bet
you that they are all faulty.
