[asterisk-users] Someone please explain FXO/FXS module/channel relationships in Zaptel configuration to me

[Robert La Ferla]

Please explain the relationship between modules from the driver  
(wctdm), the /etc/zaptel.conf file and zapata.conf.  Specifically, if  
I have a FXS module 0 and FXO module 1, what should be used in  
zaptel.conf and what should be used in zapata.conf?  Then finally, in  
extensions.conf, what is the Zap channel for dialing out?  Zap/?


% dmesg
Module 0: Installed -- AUTO FXS/DPO
Module 1: Installed -- AUTO FXO (FCC mode)
Module 2: Not installed
Module 3: Not installed
Found a Wildcard TDM: Wildcard TDM400P REV I (2 modules)

% cat /etc/zaptel.conf
fxoks=1
fxsks=2

% cat zapata.conf
...
signalling=fxo_ks
context=outgoing-analog
echocancel=yes
callerid=asreceived
channel => 1

signalling=fxs_ks
context=incoming-analog
echocancel=yes
callerid=asreceived
