I will try this later, it looks straight forward enough. Does Asterisk 
1.6 SendFax command autonegotiate T.38 (in the way callweaver does)?

Can I use a faxmachine in a linecard to terminate to T.38 on a remote 
host in asterisk 1.6? (Well I suppose I can put it in it's own context, 
use ReceiveFax to make a tiff, and SendFax the image afterwards, but 
that does seem clumsy).

I guess in Callweaver you'd use the T38Gateway command.

Is there anything of interest in digiums new Fax For Asterisk software? 
(Or is it just a version of ReceiveFax and SendFax that doesn't rely on 
spandsp?)
