User guide

The process is simple; after powering off the PBX, we plug an FXS module into the second port of the
TDM card. After powering on the system again, we add one more line to the /etc/zaptel.conf
configuration file.
fxsls=1
fxols=2
loadzone=us
defaultzone=us
To ensure that the new port has been detected and configured we run the zaptel configuration tool with
the following result:
#ztcfg -vv
Zaptel Configuration
=========================
Channel map:
Channel 01: FXS Loopstart (Default) (Slaves: 01)
Channel 02: FXO Loopstart (Default) (Slaves: 02)
2 channels configured.
We also need to add a new section to the /etc/asterisk/zapata.conf where we associate the calls
coming from the analogue phone (port 2 of the TDM card) to the context [internal_calls]
[channels]
