Hi, (Apologies for readers of Bristuff mailing as I already posted this message to the list)
My setup is: SIP hardphone ------------- <LAN> ----------- Asterisk server ---------<ISDN> Asterisk server is : Gentoo enabled with 1.0.8 bristuffed Asterisk equipped with Junghanns Quad BRI with 2 BRI ports connected to ISDN
From log files (with line numbering enabled) I've got :

My feeling (not based on hard facts yet), is that all 4 channels were not all busy. How can I can check this reading PRI INTENSE DEBUG SPAN (enormous) output ? I guess this information should be somehow readable from Channel D . As PRI INTENSE DEBUG shows both Supervisory and Informational frames, I guess channel occupation should be in Supervisory frames which I don't know yet how to read. How can I check this ? Regards
