Actually a while back Metaswitch in there 6.0 software release had a bug
where it would not pass dtmf tones if the calls was not in a connected
status state which was causing issues with ivr's with airlines ect.

It sounds to me like any AT&T IVR... They never actually answer until a
human is on the other line... I think US Air, AA maybe, and DHL are all
examples of this..


This is the same stuff that causes AT&T IVR problems when you do SIP ->
ISUP and you're stuck in a 183 and the call times out...


We get thousands of calls at our tandem for American Idol...  


On originating calls don't you bill carrier time, not connect time
anyway, so you'd still be getting paid for it? Or do I have that

I can't speak for most other carriers, but from what I've found from
personal experience is that most carriers will set up a "choke trunk
group" to a ss7 TDM for the toll free routing.

This choke group will probably only have 10 cic's associated with it and
then set up a method of overflow for the inevitable excess.

In previous call traces I have made during American idol times, I do not
see an ACM coming back, mostly it's a ANM due to no ringing and
immediate answer.

Having delt with customers in the past with choke groups,  cell phones
always seem to be able to complete calls to heavily dialed numbers in
the past.

It's usually an issue of the originating carriers capacity and not an
issue of the terminating end's capacity.

I would not say that american idol terminating end is "using resources"
as we are being compensated from our customers for being able to place
calls and the american idol numbers are compensated from american idol
for opening and running the toll free numbers and the influx of calls.

So last night I was looking around our calls flowing thru our switch
noticed a big spike in calls going to toll free numbers figured out it
was American idol.  I started digging deeper and I noticed that none of
these calls where getting a connected status back from American idol.  I
did some random test to the different numbers and confirmed was never
getting a connection status back.  I also went ahead and tested from an
att / Verizon cell phones and in both cases the cell phone still saying
calling while it was playing back the American idol msg.  so if I'm
reading everything that I have collected correctly American idol is
basically using our resources without having to compensate all the
different carries for the calls.  Anyone else seeing this?
