I installed dahdi 2.7 and asterisk 11 on Ubuntu 12.04.2 LTS. I'm having a hard time configuring a DAHDI channel. I have a AEX 808 card from Digium, the one with 8 FXO ports by my phone line is plugged into port 1 of the card.
I followed the exact same steps in http://www.voip-info.org/wiki/view/DAHDI under the Sample Installation section except I edited dahdi_channels.conf to point to the same group number as the channel number for channels 2-8 as I thought asterisk was trying to make a call from a channel other than channel 1 since they were all previously in group=0.
Here are my config files:
chan_dahdi.conf:
[trunkgroups]
; No trunk groups are needed in this configuration.
[channels]
#include /etc/asterisk/dahdi-channels.conf
; The channels context is used when defining channels using the
; older deprecated method. Don't use this as a section name.
;[phone](!)
;
; A template to hold common options for all phones.

usecallerid = yes
hidecallerid = no

With these config files, when I start asterisk, I get the following DAHDI related errors:
[Aug 8 15:56:26] WARNING[25198] chan_dahdi.c: Unable to specify channel 1: Device or resource busy
[Aug 8 15:56:26] ERROR[25198] chan_dahdi.c: Unable to open channel 1: Device or resource busy
[Aug 8 15:56:26] ERROR[25198] chan_dahdi.c: Unable to register channel '1'
This is the result of lsdahdi from the unix terminal:
### Span 1: WCTDM/0 "Wildcard AEX800" (MASTER)
1 FXO FXSKS (In use) (EC: VPMOCT032 - INACTIVE)
2 FXO FXSKS (In use) (EC: VPMOCT032 - INACTIVE) RED

7 FXO FXSKS (In use) (EC: VPMOCT032 - INACTIVE) RED
8 FXO FXSKS (In use) (EC: VPMOCT032 - INACTIVE) RED
I'm not sure why it says "In use" as there are no calls currently being processed. I'm not sure if this is the default output for an AEX808 card. How can I get my DAHDI working with asterisk? What am I doing wrong?
Result of dahdi show status in asterisk:
astersik*CLI> dahdi show status
No such command 'dahdi show status' (type 'core show help dahdi show' for other possible commands)

Any help would be appreciated.
Thanks in advance!
After much investigation, I realized that DAHDI wasn't installed properly. I removed DAHDI and asterisk from the system and reinstalled everything to make it work.
