they are sending inband progress like retards.<br><br>they are sending progress with media then playing sit instead of appropriate ISDN message.<br><br>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'm hoping you can help me figure out what's up. I've
got a disconnected number that I call on a PRI and the sequence goes like this:</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Dial number, hear ring back, see PROGRESS from telco, hear
SIT and "you've reached a DC'd number…", then
hear fast busy for 30 seconds (or so), then receive from telco that the call
state is up, and then 3 seconds later call is terminated. I've PB'd
the complete log here: <a href="http://pastebin.freeswitch.org/4549" target="_blank">http://pastebin.freeswitch.org/4549</a></span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">FYI, 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></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Any 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></p>
