What's the default order to allocation of channel at E1 (R2-digital)? Is ascending, descending or random?
And how can i do to change the order on e1 r2-digital?
I think actually there is a much simpler way.
Under controller e1, or voice-port, assign it to a trunk-group.
Under trunk-group, configure "hunt-scheme sequential up" (or down).
Reference said trunk-group instead of port in the DPs.
Unfortunately it's not easy for me to test that right now, otherwise I would have confirmed if it works.
The only way to do this is to create individual ds0-groups, and then reference them in separate dial peers with descending/ascending preference values.
