I had to reconfigure the Sangoma startup scripts even though my zap files were correct with d4,ami.
The real gotcha was in the cabling. One crossover was 1-5, 2-4, the other 1-4, 2-5 and then straight through all required for the same dialer. I have seen people post T1 crossover as 1-4, 2-4 but I thought they didn't know what they were talking about. Now I know that there are actually two different kinds.
