asterisk users - Oct 2005 - UK BT IDSN30e 'pass through' with TE205P/Avaya ArgentOffice?

Hi all,

I have a shed load of UK (BT) analogue equipment at our office (18 
phones, 6 faxes) hooked up via structured cabling to an old Avaya 
ArgentOffice phone system. The on-its-way-out phone system has an 
IDSN30e PRI interface talking to the BT exchange delivering 18 channels. 
If I were to buy a 2 port PRI card like the TE205P would this allow me 
to put asterisk in between? 

BT.EXCH <===> ASTERISK <===> Avaya PBX <===> Tphones/fax
                ||
             IP-Phones  :-)

My objective is to allow the introduction of IP phones at remote sites 
using an existing OpenVPN tunnels, and start the migration to new kit.
I would reset the Avaya config to present its POT's FXS sockets as 
single channels on the IDSN and then do the extension routing and call 
handling with asterisk.

Questions:
o Can Asterisk inpersonate a telco over IDSN 30e well enough to please a 
PBX?
o    .. with pass-through CLID?
o Avaya PBX has some very old VOIP support, so does anyone know if the 
ASTERISK <===> Avaya link may be possible over IP?
o Has anyone seen this working?

Kind regards, and thanks for any thoughts you may share.

Should do. I know someone doing this but with Sangoma hardware.

You should also ensure the PRI is really configured for EuroISDN, many
BT PRI's are actually UK ISDN which Asterisk doesn't support (it's
an
older version).
