Hi, Apologies in advance for the lengthy email.
I'm new to asterisk and have trouble with isdn4linux. The setup is very basic like this: winxp ------- asterisk -------- winxp x-lite | x-lite | pstn The hardware involved is: Compaq EVO with RH9/kernel 2.4.20-30.9. Fritz!Card PCI v2 Asterisk CVS-04/17/04-21:36:18 Basically I run: modprobe -a hisax_fcpcipnp before I start asterisk with -vvvvvgc The configs are like this: MODEM.CONF: [interfaces] context=default driver=aopen driver=i4l language=en type=autodetect stripmsd=0 dialtype=tone mode=immediate device => /dev/ttyI0 device => /dev/ttyI1 group=1 msn=0208080808 incomingmsn=* device => /dev/ttyI0 device => /dev/ttyI1 EXTENSIONS.CONF: [general] static=yes writeprotect=no [globals] TRUNK=Modem/g1 TRUNKMSD=0 [default] exten => _9001,1,Dial(${TRUNK}:0208080809,60,tr) Firewalls are disabled on all machines (doublechecked). Sip calls between the two x-lite clients work consistently. After I boot the asterisk server I can make one call succesfull to the pstn (two-way voice). Subsequent calls from x-lite to pstn only give me one-way voice; the direction that works is pstn->sip: a call is cleary established, I just cannot understand why voice is lacking sip->pstn or why it works the first time after a reboot. I had a look on the sip-clients and on the server with ethereal, and two-way traffic is happening consistently. Show channels within the CLI saw 'frames in' and 'frames out' augmenting on all channels. Looking at /dev/isdnctrl I see slightly different isdn messages, but in both cases I got a: L3DC ChangeState ST_L3_LC_ESTAB I have tried to compile chan_capi but ran into the same issue as described on a posting on april 12th: [Asterisk-Users] Trouble compiling chan_capi on Suse 9.0 As I had two servers and two fritz cards I tried both with identical software and both behave the same. I hope I have made a stupid mistake and somebody on the list can point it out to me. Every suggestion is of course most welcome. I'm a bit unsure about the machines though: both machines crashed one or more times completely (froze up) during a call to the pstn and dumped core. Basically a hardware reset was all that I could do. One of these times I was looking at the console and wrote down this: Code: 8b 38 8b 58 04 8b 68 10 c7 44 24 18 00 00 00 00 ff 4c 24 40 <0>Kernel Panic: Aiee, killing interrupt handler! In interrupt handler - not syncing Thanks, andre _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
