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>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
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

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

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>
