debugging voice calls for E1 R2 circuits in Brazil - equivalent to debug isdn931 etc

[carl_townshend]

Hi All

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?

Many thanks

Carl

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.
