Summary:                    ISDN to SIP doesn't generate SIP 180 Ringing with
Call Progress ISDN message
Description: 
When I place a call trough a SIP UA and this call goes out through an ISDN
link, the Call Progress message from ISDN is not converted to a SIP 180
Ringing message to the UA.

P.S.: Im not sure about the category of this issue, BTW I believe it is a
channel related thing.

I'm not sure what the actual problem is.
I would translate the messages as described above.

And what do you want to reproduce? A connect without alerting?
That happens where calls are auto-answered, so will almost certainly be
true for data calls. IVR systems might also do it. However there's no way
to do it with Asterisk AFAIK even if that might suggest itself for calls
answered within the dialplan.
