asterisk users - Oct 2011 - Questions on Dahdi

I have naive question. I do not have any hardware on my asterisk host. All I
have are either SIP trunk for DID or hardware ATA which bridges the asterisk
to PSTN. Do I need Dahdi install? Do i have ztdummy for timing issue? I
encounter problem in this when I try to install Dahdi latest but I found it
is not running, Instead it runs when service starts but I can't find its
status when I type in service dahdi status.

I am using Asterisk 1.8.7 on centos 5.7 32 bit.

If you have no hardware in the server for PSTN connectivity, then you do 
not need any card drivers.  If you do not use MeetMe, you would not need 
any kernel modules either, but my impression is that it doesn't hurt in 
install at least the dahdi.ko module.

When 'service dahdi start' is run, it loads the dahdi.ko module as well 
as any modules in the /etc/dahdi/modules config file.  If you have no 
hardware, it is safe to comment out all the modules.

If you have no card modules loading, 'service dahdi status' returns 
nothing.  If you use the command 'lsmod | grep dahdi' and you see a line
similar to the one below the kernel module is loaded.


dahdi                 186420  0


If you see that, you are good to go.
