[Asterisk-Users] [ISDN] Problem: Device '/dev/ttyI1' lacking dialtone

[Patrick de Kok]

All,
 
Currently I've got my Asterisk machine running smoothly on IP bases. Meaning I can reach all phones or softphones within my LAN or remote LAN's via VPN. The next step for me is connecting it to the PSTN network.
 
After some tweaking with the modem.conf I got the i4l driver running correctly, and it appears that my Fritz! ISDN v2 card is working correctly.
 
I have added the following to my extension.conf file:
 
[extensions.conf]
exten => 200,1,Dial(Modem/ttyI0:00104431040)
exten => 201,1,Dial(Modem/ttyI1:00104431040)
exten => 202,1,Dial(Modem/ttyI2:00104431040)
exten => 203,1,Dial(Modem/g1:00104431040)
 
When I dial either extension it shows the following error:
 
    -- Executing Dial("SIP/102-36a5", "Modem/g1:00104431040") in new stack
    -- Called g1:00104431040
Oct 14 09:42:41 WARNING[2901]: chan_modem_i4l.c:380 i4l_read: Device '/dev/ttyI1' lacking dialtone
    -- Hungup 'Modem[i4l]/ttyI1'
  == No one is available to answer at this time (1:0/0/0)
  == Auto fallthrough, channel 'SIP/102-36a5' status is 'NOANSWER'
 
I have found some references in previous mailings, but none of them seem to solve the problem in my situation.
 
I hope someone here can help me!
 
Thanks in advance,
 
Patrick
