E1-R2 cas connection type troubleshoot

[Sam Nk]

Hello all,

we are having below configuration for one of the Sites, that is E1 R2-cas

controller E1 0/0/0
 framing NO-CRC4
 ds0-group 1 timeslots 1-15,17-31 type r2-digital r2-compelled ani
 cas-custom 1

as I understand debug isdnq931 will not work, when I run debug vpm all, I get huge chunk of data. Is there any good way to troubleshoot calling issue for E1 R2 type connection?

Rgds,

[Sam Nk]

any suggestion's ?

For R2 you can use debug vpm signal.

debug voip vtsp all may also be helpful.  If that's too much, you can do debug voip vtsp default, and then add session as well if you need.
