[Solved]DAHDI - unable to register channel after reboot

Postby peace_d641 » Mon Nov 05, 2012 7:41 pm

Hi all,

I'm using a Digium Wildcard TE120P card, with Asterisk 1.8.17.0 and DAHDI 2.3.0.1

After my first installation completed (without rebooting), Asterisk and dahdi are both working fine, i'm able to make calls through dahdi. But after i reboot the server, it will show me:

Code: Select all
[Nov  6 09:03:12] WARNING[10558]: channel.c:5660 ast_request: No channel type registered for 'DAHDI'
[Nov  6 09:03:12] WARNING[10558]: app_dial.c:2341 dial_exec_full: Unable to create channel of type 'DAHDI' (cause 66 - Channel not implemented)
  == Everyone is busy/congested at this time (1:0/0/1)


And when i run 'module load chan_dahdi.so', this is what i got:

Code: Select all
Command 'module load chan_dahdi.so' failed.
[Nov  6 09:35:40] WARNING[10908]: pbx.c:5833 ast_register_application2: Already have an application 'DAHDISendKeypadFacility'

[Nov  6 09:35:40] ERROR[10908]: chan_dahdi.c:16851 build_channels: Unable to register channel '1-15,17-31'


I personally think this is not caused by configuration as i can make calls before rebooting, i've been searching this problem for days and i found a post may related to this, which is exactly the same problem as me:
http://forums.askozia.com/index.php?topic=1157.5

and also when i tried to use other vevrsions of Asterisk and Dahdi, i got the same problem.

Any help will be appreciated.

Does Dahdi seem to start properly on reboot? Do you get any errors loading Dahdi drivers in /var/log/messages?

No, dahdi service can start without any problem.

Is DAHDI starting properly on boot, or only when you start it manually? I.e., after boot, does dahdi_scan report all your hardware?

actually not, if i run 'service dahdi restart', it will get

Code: Select all
Unloading DAHDI hardware modules: ERROR: Module wcte12xp is in use
ERROR: Module wcte12xp is in use
ERROR: Module dahdi_voicebus is in use by wcte12xp
ERROR: Module dahdi_echocan_mg2 is in use
ERROR: Module dahdi is in use by dahdi_echocan_mg2,wcte12xp,dahdi_voicebus
error
Loading DAHDI hardware modules:
  wcte12xp:                                                [  OK  ]

Running dahdi_cfg:                                         [  OK  ]



UPDATE:

I think my problem is caused by Asterisk, module chan_dahdi is not loaded by Asterisk.
After the first time i complete the installation of Asterisk, i can directly make calls through DAHDI, but once i restart asterisk service, i will get that error, which says unable to register channel DAHDI.

Cheers!
First of all I'd recommend:
1. /etc/init.d/asterisk stop
2. /etc/init.d/dahdi restart - will you get errors?
3. open second console and run tail -f /var/log/asterisk/messages
4. /etc/init.d/asterisk start
5. run chkconfig --list | grep dahdi
You'd see something like:
dahdi 0:off 1:off 2:on 3:on 4:on 5:on 6:off

Finally the problem is solved.
DAHDI service must start after asterisk, or it will get that error.
Thanks for all the helps above.

That has never been true in the past. The dahdi modules need to be loaded before chan_dahdi, otherwise, it will fail to open the dahdi device.

If i run dahdi first, then asterisk will not be able to register channels for dahdi, only i run dahdi after asterisk can solve this.
But anyway, at least this is the way to solve my problem. :)

Hi All!

Need urgent help. I'm having the same problem. My Elastix 2.20 (Release 21) with Asterisk 11.5.0 was working just fine until yesterday. I then decided to try the new addon SmartFink - which I installed via the web addon page of Elastix by clicking the "Install" button.

After that I started receiving the "All circuits are busy" message when I tried to make any outboud call. I looked into the Asterisk Log (i.e /var/logs/asterisk/full) and I see that the main culprit seems to be:
Code: Select all
Channel.C: No Channel Type registered for 'DAHDI'
app_dial.c: Unable to create channel of type 'DAHDI' (cause 66 - Channel not implemented)


Based on what I read in these posts - I tried to stop the asterisk service and then restart and manually load chan_dahdi.so - however that fail.

I also looked for the log file when I start asterisk using the -vvvvvvvvvvvvvvcfg option - but not sure where to find this. I don't have a messages log file under /var/log/asterisk
I only have the full and related log files in there. I'm herewith attached he content of the log file and also the chan_dahdi.conf and other related file.

Need urgent help!!!

What exactly are the messages from asterisk (cli) when trying a

Code: Select all
module load chan_dahdi.so


As the channel is not loaded You should get some error-messages about when trying to load the module
