Hi to everyone!

I am new to this list and i want to greet you all!

 

I am trying to install Asterisk on a Fedora Core 3 Distribution with a
Digi Datafire Micro V ISDN Card.

I know that I have to use the ISDN4Linux so in modem.conf  I set the I4l
driver ,the msn and device.

 

Modem.conf

[interfaces]

context=remote

;driver=aopen   ; modem by AOpen

driver=i4l      ; isdn4linux - an alternative to i4l is to use chan_capi


;

; Default language

;

;language=en

type=autodetect            

;type=aopen

stripmsd=0

dialtype=tone

;dialtype=pulse

;mode=answer

;mode=ring

mode=immediate

; ISDN example (using i4l)

;

msn=0415040331

device => /dev/ttyI0

 

I noticed that my card was detected as eth1 by the system and not as
ttyI0, How can I create ttyI0 devices?

If I start Asterisk the error returned is: 

 

== Parsing '/etc/asterisk/modules.conf': Found

 [chan_modem.so] => (Generic Voice Modem Driver)

  == Parsing '/etc/asterisk/modem.conf': Found

  == Loading modem driver chan_modem_i4l.so => (ISDN4Linux Emulated
Modem Driver)

Jan 10 15:56:51 ERROR[13454]: chan_modem.c:956 load_module: Unable to

  == Unregistered channel type 'Modem'

Jan 10 15:56:51 WARNING[13454]: loader.c:345 ast_load_resource:

  == Unregistered channel type 'Modem'

Jan 10 15:56:51 WARNING[13454]: loader.c:391 load_modules: Loading
module chan_modem.so failed!

 

Clearly I have to create the ttyI0 device

Every suggestion will be appreciated!

 

Thanks to all and sorry for my mistakes!

 

Denis
