We have a Gateway in Brazil, I believe these to use E1-R2 signalling.
I want to debug calls on there the same as doing a debug isdnq931, how do I do this?
Debug vpm signal is the best debug command for these. Here is a link for Cisco official T1-CAS troubleshooting guide, it's old but relevant. If you google for "cisco t1-cas r2 troubleshoot" you will find many good links as well.
