spontaneous hangups are the biggest one.
Ok, understood. But I'm still very curious: what is the wife test ?! :)

This is precisely why I said he was getting beyond the practical. :-)
Because my customer bought a custom server with only _two_ PCI full
length slot and those are used for the two TDM2400 cards (40 fxs). I
wasn't aware of this "ANSWER detection" problem and my solution is
aimed to an hotel, so the billing is, how to say, mandatory... Then I
have to pay some piece of hardware that _does_ detect answer and that
does not request any PCI slot... the cheaper I've found (and with
good reviews) is the Inalp Patton. Could you help me understanding
if, with an ISDN device connected to asterisk with SIP, I could be
reasonably sure to get correct CDR billing records? And what about
the case that Andrew pointed out: the "the number you have reached
has been disconnected" case... would I get a billing record or not,
using an ISDN device connected to Asterisk with SIP ?! The telco does
not bill for those answers, so the hotel's guests probably expect
themselves not to be billed too...
PBXs in Italy seems to react to the Telco "scatti" ("marks", "billing
pulses"). Isn't there such a concept in US? Is there a way to
intercept such Telco events?
