[asterisk-users] TELUS British Columbia PRI Settings

I am having some difficulties getting my Asterisk box to find the d-channel from a TELUS PRI and am waiting to hear back from one of their techs.  In the meantime I thought I would check with the brilliant people of the mailing list.


As I understand it is a T1 connection, not an E1 and I am using a Digium TE121 with hardware echo cancellation.  I have green lights on the back of the card and the PRI connection, which go red when I do a dahdi restart command and come back to green once it is finished.


I know from our other system that the frame and coding are ESF and B8ZS so it must be something in the signaling of the channels.  My chan_dadhdi is below, the commented out lines are ones I have tried.  I’ve also tried moving the dchannel  around, 12 through 24.  Does anyone see anything blatantly wrong?  


Thanks, Jeremy
