10.0pt;font-family:Arial;color:navy'>Of course, you are correct. They are
retarded, and they are sending progress inband. The only reason I can do tone
detect or anything like it is because the originate app doesn’t finish until
the channel goes from PROGRESS to UP. About the only thing I can think of is
to have OZ take an ALERT message with progress IE containing the “I’m a retard,
here’s inband messaging” info and have that move the channel state to UP. Or
if there’s another way for the originate app (or bridge app, depending on
whether I’m using API or not) not to get snagged on this particular scenario
then I’m all ears.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I’ll keep looking for other goofy cases
like this. The application that I’m looking at right now is essentially a “disconnected
number verifier” program. I’m trying to write an auto dialer that gets fed a
list of phone numbers that we’re pretty sure are disconnected and does its best
to verify that fact. Of course, when the friggin’ telco sends inband progress
instead of a q931 message indicating an issue then we’ve got to play these
silly games.<o:p></o:p></span></font></p>

10.0pt;font-family:Arial;color:navy'>P.S. – when dialing out via a VoIP
carrier, what kinds of things happen when a disconnected number is called? Does
the VoIP carrier also have to deal with the retardation from the telcos? If
so, how well does it work? Just curious if a SIP account would be good for
this kind of application…<o:p></o:p></span></font></p>

they are sending progress with media then playing sit instead of appropriate

on trick you can do is try adding tone_detect app like some of the fax examples
but for one of the 3 sit frequencies and transfer that call to hangup.<br>

I tried it with both with and without ignore_early_media. When ignoring
early media I just get 60 seconds of FS internal ringback tone then I hear that
the call failed. When not ignoring early media is when I get the SIT
tone, etc. and that's also what is in pb 4549.</span></font><o:p></o:p></p>

thoughts on how to handle a call like this? FS doesn't consider the call
"connected" because telco sends us PROGRESS_MEDIA but doesn't
actually say that the call is "up" – at least as far as I can tell.</span></font><o:p></o:p></p>
