TDM400P 4 port FXO - only one line can't send or receive

I have a 4 port FXO TDM400p in fairly recent dell that’s been running great for a couple of years. I’m running Trixbox 2.0 (Asterisk 1.2.13) with the 1.2.11 Zaptel drivers (for some reason none of the lines work w/ the newer drivers). We have four lines in our office that been working fine w/ our old traditional PBX. 3 of the 4 lines work fine on the Asterisk box. The line that doesn’t work is the primary line of a hunt group that is set up at the phone company and also is the source of our incoming SDSL signal. I’ve tried a DSL filter on the line and their was no change. It doesn’t matter which channel I plug the lines into, the behavior is the same, all the other lines send and receive calls except the primary. When I try to make calls from that line the phone rings a couple times then just static. It stops ringing but doesn’t place the call or go to a dial tone. When I make calls to the line they do not show in the panel as coming in on any channel and the phone just rings and rings. I’m out of ideas on things to try. The only thing different about this line is that it the primary line in the hunt group and carries the DSL but I don’t see why either would affect my internal setup. Any ideas would be much appreciated I’m stuck.
