[RESOLVED]Issue with DAHDI module

system · November 12, 2011, 5:25pm

Hello everybody

I have some issues with my analog FXO card. It seems to be correcty installed, but impossible to load the module in Asterisk.
I run Asterisk 1.8 with an anolog 4 slots card. On the 1st slot, I have a FXO, on the second : FXS, and the 2 others are empty.

Dahdi starts up without any problem :

flo@pbx:~$sudo /etc/init.d/dahdi restart
    Unloading DAHDI hardware modules: done
    Loading DAHDI hardware modules:
       wctdm: done
    Running dahdi_cfg: done.

    flo@pbx:~$lsdahdi

      2 EMPTY
      3 unknown    Reserved
      4 unknown    Reserved

Scan should be OK :

    flo@pbx:~$sudo dahdi_scan

    alarms=OK

    irq=11
    type=analog
    port=1,FXO
    port=2,FXS FAILED
    port=3,none
    port=4,none

Here is the dahdi_cfg :

    flo@pbx:~$ sudo dahdi_cfg -vvv
    DAHDI Tools Version - 2.5.0.2

    DAHDI Version: 2.5.0.2

    ======================


    Channel map:

    Channel 01: FXS Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 01)

    1 channels to configure.

    Setting echocan for channel 1 to mg2

Now the asterisk settings :
chan_dahdi.conf:


    ;[trunkgroups]

    [channels]
    language=fr
    busydetect=yes
    busycount=3
    #include dahdi-channels.conf

    callerid=asreceived
    group=0
    context=from-pstn
    channel => 1
    callerid=

From Asterisk, impossible to load the module chan_dahdi.so

    pbx*CLI> module load chan_dahdi.so
    Unable to load module chan_dahdi.so
    Command 'module load chan_dahdi.so' failed.
      == Parsing '/etc/asterisk/chan_dahdi.conf':   == Found
      == Parsing '/etc/asterisk/dahdi-channels.conf':   == Found
    pbx*CLI>

When I delete “channel => 1” in the dahdi-channel.conf, I am able to load the module, but no channel is available.

Does someone have any idea?

Is that output from “module load chan_dahdi.so” with full verbose and debug logging enabled? Also, I’m guessing you know your FXS module is having problems? Since you only have chan 1 configured in your /etc/asterisk config files, I doubt the failed FXS module is the reason for the failure to load though. Running “dmesg” should provide more information why it’s failing the load.

Thanks for your answer.
I forgot to mention that I just want to setup my FXO module for now. I don’t think I will use the FXS, as all clients are SIP phones.
Yes, when I launched the module load command, both verbose and debug were set to 5. I just had this error message, nether error nor warning message was showing up.

I launched dmesg command, and I have to say that was very helpfull :

So if I understand well, a wire should be unplugged in my server…
I am going to check it next monday, as my server is not at home.

Thanks for your help.

Hi

I still have an issue with this…
The power cable was unplugged… I re plugged it, but I am still not able to load the dahdi module.

Here is now the result of dmesg :

Hi

I finaly resolved this issue by editing the file :
/etc/modprobe.d/dahdi.blacklist.conf :

blacklist wct4xxp
blacklist wcte12xp
blacklist wct1xxp
blacklist wcte11xp
blacklist wctdm24xxp
blacklist wcfxo
blacklist wctdm
blacklist wctc4xxp
blacklist wcb4xxp
blacklist netjet
blacklist avmfritz
blacklist hfc4s8s_l1
blacklist netjetpci
blacklist hisax
blacklist hisax_fcpcipnp
blacklist hisax_isac
blacklist crc_ccitt
blacklist isdn
blacklist slhc
blacklist capi
blacklist capifs
blacklist kernelcapi
blacklist kernel_capi

And now it works fine!

Thanks for your help.
