[Asterisk-Users] isdn4linux

[Nick Knight]

Hello All,
 
I was just after a few pointers. I have just setup my Redhat 9 linux box
with asterisk. Internal SIP call working fine. 
 
My Eicon ISDN card turned up today so - plugged it in and went through
the modem.conf. It reports unable to open /dev/ttyI0 
 
The problem is I have never used ISDN with Linux - let alone a telephony
app - and I have no idea even where to start. Some pointers would be
appreciated.
 
Regards
 
Nick
