You are most welcome.
Last time I was in Houston was on the way to Galveston Island. The most
miserable environment I have ever been in, thanks to the Gulf. Extremely
high humidity and 80 plus degrees.
And I have grown gills from living in Washington D.C. for so long.
Glad it was an easy fix.
Sometimes it's the really simple things that grab us!

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

Just to let you guys know, we're looking into this to see why this might
be happening. We'll keep you posted when we find out what's wrong.
