Gordon,

Did you hijack someone else's thread?  You should really start your own.

Anyways, I have had great luck with TDM card to TDM card faxes on the 
same box. 

I think you want "echocancelwhenbridged=no" at least that made TDM 
faxing almost perfect for my installations.

The only thing I would be concerned with are the sometimes painful IRQ 
issues.

Thanks,
