I configured Asterisk as shown in http://www.voip-info.org/wiki-Asterisk+ISDN4Linux
The box running Asterisk under SuSE 9.0 Pro has a "Eicon Diva Server BRI 2M" ISDN card attached and it seems to be recognized by the system.
I added the following lines to:
* modem.conf driver=i4l ... group=1 msn=+34xxxxxxxxx device => /dev/ttyI0 device => /dev/ttyI1
---
* extensions.conf
TRUNK=Modem/g1
...
exten => mmielke,1,Dial(${TRUNK}:0yyyyyyyy) ;yyyyyyyy is cell-phone number...
...
---
With all this, I get the following error messages when starting Asterisk:
---
...

Then, because ISDN devices are "seen" as /dev/ipppN, I modified modems.conf to have these two lines instead:
---
device => /dev/ippp0
device => /dev/ippp1
---
But when I launch Asterisk, it never goes beyond this point:
---
[chan_modem.so] => (Generic Voice Modem Driver)
== Parsing '/etc/asterisk/modem.conf': Found
== Loading modem driver chan_modem_i4l.so => (ISDN4Linux Emulated Modem Driver)

This is a CPU-grinder, as it reaches a 99.9% usage and the only way to stop this is hitting ctrl-c...
On the messages file I see:
---
Mar 29 16:35:22 pbx kernel: ippp, open, slot: 2, minor: 0, state: 0000
Mar 29 16:35:22 pbx kernel: ippp_ccp: allocated reset data structure c5480000
Mar 29 16:35:50 pbx kernel: ippp_ccp: freeing reset data structure c5480000

Am I overseeing anything obvious?
Every hint on this issue will be much appreciated.
TIA and regards, Martin
