Hi,

 

I could test time ago a digium card with an alcatel oxe using an E1 line-side. I could not make a full set of test  like transfer or hold. Also I can not recall if I use asterisk or freeswitch, i think I used fs but i can not be sure.

 

What I can tell the settings was quite stright forward. The only issue what I got was about user persimision freetdm to run dahdi.

 

I think you question could be answered by Moises Silva who is the main constributor of FreeTDM.

 

I found this on net, coul help you test:

Ah Steve (maybe I do not understand your response) .... fxs and fxo in a digital E1 is posible. Some fabricants use CAS to emulate a fxs station in each circuit, so you can get 30 "analog" station in a E1. This protocol have presence in several pbx (Alcatel, Nortel, Meridian, Siemens, Avaya, etc) and is used by IVR. Just for infomation look at:

It is a protocol very nice and simple
