Anybody has an idea on how to configure an E1 R2 in UC520 with an integrated T1/E1 card. We have gotten the E1 port up and running but we cannot receive or make a any calls. We are in Mexico, we configured the E1 port the following way:
controller E1 0/3/0
dsc-group 1 timeslots 1-15,17-30 type r2-digital r2-compelled ani
answer-signal group b-1
the E1 interface seems up and running fine, but we cannot make or receive calls.
any help will be greatly appreciated.
