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.

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:

and also when i tried to use other vevrsions of Asterisk and Dahdi, i got the same problem.
Any help will be appreciated.
