Ronnie I have 4 non-PRI's connected to a Nortel 11C and I had played with PRI connections before and got them working. If you want to call me we can go over your set up and compare with mine.

I've found it useful (on occasion) to power cycle the asterisk box too, as this _forces_ the far end of the E1 (T1 in your case) to start afresh. Tim. Tim Panton www.mexuar.com/cards.html

Thank you all for the response. The fix was power-cycling the entire server. All my settings were correct. Runs great now.
