[asterisk-users] can not receive calls through pri

[Uros Djokic]

Hi,

I have problem using Asterisk.I have isdn-pri and openvox d110p card in my
computer.They are connected with RJ-45 (1,2,4,5 pins to the card and all
pins to the isdn done by telco workers). I got green led on isdn which is
sign that isdn is working and that is connected to openvox, right ?  I
compiled newest versions of libpri zaptel and asterisk and had no problems
during that. When I started services I can not receive any calls.No
indication that any call is coming to Asterisk.When I dial number (to my
line coz it is IN service so they can only call me not other way) I can hear
telco message then few seconds of silence and busy signal. On cli I can not
see anything.By the way I use Fedora 9 x64 kernel (I tryed with i386 kernel,
with different machines,different distributions too but same problem
occurred. Here are my relevant files :

/etc/init.d/zaptel restart gave me this :

 Even when openvox is not connected to isdn i get online...OK is it ok ? How
can it go online when it is not connected ?!

lsmod | grep zaptel

ztcfg -vvvv gave me this :

 Like it can not open D-channel 16 ? resource/device busy ? Is it card
problem ? Is it indication that card is not good ?
As far as I can see only wcte11xp is using zaptel nothing else.I eliminated
hesiox or something (linux isdn) module so wcte11xp is alone on zaptel and
zaptel is alone on crc_citt .wcte11xp is also alone on interrupt.
I have also seen those messages in CLI (1 per second)
NOTICE chan_Zap.c: pri_dchannel: pri got event: hdlc bad fcs ( 8 ) on
primary D-channel of span 1

Can you help me with that ?
