Use 2 X100P cards

hi, i have 1 X100P card up and running, but i can’t get the second to work.
I’ll provide the contents of the appropriate config files.

zaptel.conf:

fxsks=1
loadzone=us
defaultzone=us

zapata.conf:

[channels]
usecallerid=yes
hidecallerid=no
callwaiting=no
threewaycalling=yes
transfer=yes
echocancel=yes
echotraining=yes

context=incoming_zap1 ;incoming calls go to [incoming] in extensions.conf
signalling=fxs_ks ;use FXS signalling for an FXO channel
channel => 1;PSTN attached to port 1; set in zaptel.conf

extensions.conf

[incoming_zap1]
;incoming calls from the FXO port are directed to this context from zapata.conf
exten => s,1,Dial(SIP/1001,20)

now i would like to get the second FXO card to work as well and make another context for this card like:

[incoming_zap2]
;incoming calls from the FXO port are directed to this context from zapata.conf
exten => s,1,Dial(SIP/1002,20)

but i’m not sure what i have to change in zaptel.conf and zapata.conf

also another question.
is it possible to call via a sip phone to a fixed line through the X100P card?
thus not calling in to another voip provider but straight onto our own fixed line?
