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 a SIP expert. Does SIP require a Ringing message before a connect?
In that case the only solution I see is a state machine that sends a
ringing when the connect message is received and no Ringing was sent so
far.

Translating a proceeding message into ringing will surely cause strange
effects.
