Hi all,I'm using A400P with one FXO module. I have done everything according to manualbut when I try to place a outgoing call, I have this warning:

Warning[3592]:app_dial.c:1547 dial_exec_full: unable to create channel of type 'dahdi' (cause0 unknown)

asterisk version:1.6.1.17

I have run these commands
code]modprobedahdi

modprobe wctdm
dahdi_cfg -vvvvvvv

dahdi tool version - 2.2.1

DAHDIversion 2.2.1

Echo Canceller(s): MG2 Configuration
================

Channelmap: Channel 01: FXS Kewlstart (default) (Echo canceler: mg2) (Slaves: 01)


1channel to configure.
Setting Echo canceler for Channel 1 to mg2[/code]

althoughloading drivers is successful, when using Dahdi show channels, I see no result:( I don't know what to do....

thanks for your help

Hello,
Have you added the line"#include dahdi-channels.conf" at the end of chan_dahdi.conf?
Furthermore, remember to execute the command"module load chan_dahdi.so" on the asterisk CLI.
Please have a try in this method, let me know for any question from you!

Dear Joe.Yung
thanks for your answer but still it doesn't work and I'm so confused that I can't even ask questions.
these are my configues:

system.conf:

# If you edit this file and execute /usr/sbin/dahdi_genconf again,
# your manual changes will be LOST.

I included the dahdi-channels.conf in the file and I run the command that you said but it gave me a warning that this module is already loaded...

can you help me again? thanks.

Hello,
Please send your server SSH account to me!
Let me check it for more details!

dear Joe,
I can't...... it's a pilot project, and our administrator won't let me to do it... sorry for all the trouble but if you tell me what should I check, I will run the commands and tell you the result...
again thank you for your support.

Hello,
Enable the debug parameter in /etc/asterisk/logger.conf. And regenerate channels again by:
1.modprobe dahdi
2.modprobe wctdm
3.dahdi_genconf
4.dahdi_cfg -vvvv
Add the line"#include dahdi-channels.conf" at the end of chan_dahdi.conf.Start asterisk and have a look what is information being shown when you execute "dahdi show channels"

For the dialplan, please replace the existing with this to test:
[from-internal]
exten=>_X.,1,Dial(DAHDI/1/${EXTEN})
exten=>_X.,2,Hangup()

[from-pstn]
exten=>s,1,Answer()
exten=>s,n,Dial(SIP/100)
exten=>s,n,Hangup()

register one extension in sip.conf. Add these lines at the end of the /etc/asterisk/sip.conf
[100]
type=friend
username=100
secret=100
host=dynamic
context=from-internal
With this dialplan, make some test calls!
Please let me know of any question if you experience.
