Setelah driver dahdi sudah terinstall dan sudah dapat mengenali hardware digium.

Tinggal mengkonfigure chanel di dahdi dengan tools dari dahdi_genconf setelah itu restart agar konfig dikenali system.

# dahdi_genconf
# /etc/init.d/dahdi restart

Hasilnya dapat di cek dari dahdi_tools.
Pastikan alarm untuk port yang terkonek ke E1 Telkom tertulis OK.

Voip:dahdi or zaptel

By human

http://www.mail-archive.com/linux-il@cs.huji.ac.il/msg56916.html

Asterisk 1.4.x , for x > 21 , can be built to support either Zaptel or
DAHDI. This is a build-time decision. 1.6.0 and above only support
DAHDI. 1.4.21 and below only support Zaptel.

As a very practical test:

# strings /usr/sbin/asterisk | grep /dev | egrep 'zap|dahdi'
/dev/dahdi/timer

# lsmod | grep dahdi
dahdi_echocan_mg2      10248  120
dahdi                 196552  4 dahdi_echocan_mg2,wct4xxp
crc_ccitt               6337  1 dahdi

# dahdi_hardware

By human

[Feb  9 16:34:51] ERROR[4907] asterisk.c: Asterisk has detected a problem with your Zaptel configuration and will shutdown for your protection.  You have options:
        1. You only have to compile Zaptel support into Asterisk if you need it.  One option is to recompile without Zaptel support.
        2. You only have to load Zaptel drivers if you want to take advantage of Zaptel services.  One option is to unload zaptel modules if you don't need them.
        3. If you need Zaptel services, you must correctly configure Zaptel.
