FreePBX Installation / Upgrade

Hi,
I have installed asterisknow1.5.0 and digium tdm400p card.

my dahdi_cfg -vvv shows

[root@localhost ~]# dahdi_cfg -vvvv
DAHDI Tools Version - 2.1.0.2

DAHDI Version: 2.1.0.4
Echo Canceller(s): MG2
Configuration

Channel map:

Channel 01: FXO Loopstart (Default) (Echo Canceler: mg2) (Slaves: 01)
Channel 02: FXS Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 02)

2 channels to configure.

Setting echocan for channel 1 to mg2
Setting echocan for channel 2 to mg2

But dahdi show channels in * cli gives error.

localhost*CLI> dahdi show channels
No such command ‘dahdi show channels’ (type ‘help dahdi show’ for other possible commands)

Can anyone tell me why i get this problem?

There is probably something misconfigured in your chan_dahdi.conf file (or zapata.conf if your still using that). I just ran into this recently and it had me stumped for a couple of hours until I realized I had some channels misconfigured.
