asterisk users - Sep 2006 - Any one knows if I can connect SS7 to Asterisk, (with a TE405P or other) ???

Hi I need to connect at least 2  (and 2 more in the future)   links to a 
switch via SS7,

does anyone knows if this can be done with Digium cards?  

if not, which box could I use to convert from SS7 to isdn, 

(could anyone please recomend one of these boxes, and let me know a 
ballpark price figure)

regards

If you're connecting to a carrier's SS7 network, I'm pretty sure you
need to be using carrier-lab-approved hardware -- and very probably
software -- to do it.

Things may have changed since, oh, 5 or 6 years ago when I last paid
any close attention to SS7, but last I heard, the ingress ports to that
network are not filtered enough for them to let just anyone hook up to
them.

That said, those links *used* to be V.35 off the terminal equipment; I
don't know whether they're using T-spans for them now, but even if they
are, I suspect you might need custom *drivers*, not just custom
app-level software.  But IANASS7E.

You can check out libss7. I developed it on Digium cards.  It is an ss7 
implementation in a library that you can use with chan_zap to talk ss7 
(like libpri).  You also might want to get on the asterisk-ss7 mailing 
list.  There's a lot more talk about this there.
