John,
you were right on the money: I've found that the two lines that gave me
problems had the polarity reversed. Correcting it solved the problem. I
wish I had checked that last week - before spending hours on
troubleshooting ...

Apparently it is - unlike the Sangoma A200 which worked with either
polarity.

Thanks for your help I can't say how much I appreciate it.
Let me know if you're ever in the Houston area: I'll buy you a beer, or
two ;-)

Cheers,
Thomas
