Source of zapata.conf generation?

Hi,

zapata.conf gets generated on startup. Somehow the lines

signalling=fxo_ks
channel => 1
signalling=fxs_ks
channel => 4

get generated. These lines are not in zapata.conf.zapscan. Where do they come from? I want it to have this instead:

context=internal
signalling=fxo_ks
channel => 1
context=incoming
signalling=fxs_ks
channel => 4

if I change zapata.conf.zapscan to have this:

context=internal
signalling=fxo_ks
channel => 1
context=incoming
signalling=fxs_ks
channel => 4

and reboot the server, zapata.cong will have this:

context=internal
signalling=fxo_ks
channel => 1
context=incoming
signalling=fxs_ks
channel => 4

signalling=fxo_ks
channel => 1
signalling=fxs_ks
channel => 4

Please advise, thanks!
