Sample Configuration of Sangoma card with another TDM Card

It’s possible to configure Sangoma card with another TDM card. Basically you can use wancfg_zaptel (setup-sangoma incase of Trixbox) and configure Sangoma hardware.Than manually hand edit /etc/zaptel.conf and /etc/asterisk/zapata.conf(zapata-auto.conf incase of Trixbox) for span/channel configuration for another card. And finally add modprobe < module name > in sangoma start script (/etc/wanpipe/script/start)

Here is sample configuration of Sangoma AFT series T1/E1 card configured as E1with Digium^® 4 port Analog card 2 – FXO port 2 –FXS port
