[asterisk-users] DAHDI

[Ira]

I finally decided it's been long enough using my ancient HP junker 
and I built a Atom 330 based machine to replace it. I've installed 
Centos 5, Dahdi and Asterisk 1.6.2.

After a bit of struggles getting the 1.2 version files converted to 
1.6 almost everything seems to be working.

All my SIP lines seem to work and calls come in as expected and all 
my DAHDI lines work with incoming calls, but I can't make an outgoing 
call on a DAHDI line.

The simplest line is:

    exten=> s,1, dial(DAHDI/1)

which says it can't create a DHADI channel and gives an unknown error 0.

As far as I can tell everything is OK, but clearly it's not and I 
don't understand why incoming calls work and outgoing calls don't.

Dahdi is using a TDM400 with 4 FXO modules. The messages at boot time 
seem correct and "dahdi show channels" seems to indicate all three 
dahdi channels I use are present and working.

I'm open to any suggestions.
