The automatic configuration script does not work with Digium digital line cards. These will need to be configured manually. Two files will need to be edited for Asterisk to be able to use these cards. Here, we will see how to configure a Digium TE110P card.
From the Asterisk server, we will need to edit or create a file called zaptel.conf.
[root@asterisk1 ~]# nano /etc/zaptel.conf
Now we need to type in the following information:
# TE110P T1 Card / Typical US Settings span=1,1,0,esf,b8zs bchan=1-23 dchan=24
Hit Ctrl+O to save our changes and Ctrl+X to exit.
This information has now defined the card and how it communicates with the outside world as well as its capacities.
Next, we need to define the channels and how they function within Asterisk.
[root@asterisk1 ~]# nano /etc/asterisk/zapata.con
Type in the following information:
[channels]
switchtype=national
context=from-pstn
signalling=pri_cpe
group=1
channel => 1-23
language=en
context=from-pstn
signalling=fxs_ks...
