Just for the record.  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.

Thanks,
