they are sending inband progress like retards. they are sending progress with media then playing sit instead of appropriate ISDN message. 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.

Guys,
I don't know if this is "normal" or not so 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:
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: http://pastebin.freeswitch.org/4549
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.
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.
Thanks, Michael
