Yes, we use a TE410P to connect to an E1  (ISDN-30)  line,  and also to an 
Eicon Diva card  (which itself is meant to connect to an E1)  in a server 
running Hylafax.  It all works beautifully, with outgoing faxes being routed

You just need to specify

signalling = pri_net

and a suitable default context in the appropriate span in your 
chan_dahdi.conf.  (You might want to use NoOp(${EXTEN}) in your first iteration 
of this default context, just to see exactly how the called number is getting 
sent through from the CPE.)

(pri_cpe is Customer Premises Equipment -- i.e., something such as you would 
plug into the box provided by your telco; pri_net is NETwork -- i.e., a box 
such as a telco might provide.)
