Hello Trixter, I have also talked to the carrier and they confirmed that early media feature is enabled and that I would have 90 seconds for playing early media announcements. I've sent them my full isdn trace and they've told me that I do send progress information and even the correct progress indicator, but - as I've already mentioned - the progress information that I send is in the wrong message type. It's in PROGRESS and they expect it to be sent in either ISDN message-type "Setup", "Callproceeding" or "Alerting". Sorry,I can't get it more clearly... Even Sangoma has told me that it may be a problem with libpri, zaptel or asterisk.
