Note that the channels in my example below are all channel => 1. You'll need to change that so it jibes with your ZAPTEL.CONF file...

You'll want to learn all about Channels and groups. You can try here:
http://www.voip-info.org/wiki/view/Channels+and+Groups
.
I've assumed that you have 4 FXO modules (to support 4 external phone lines) and 4 FXS modules (to support 4 local extensions).
Essentially you'll need
to define "group"s in your ZAPATA.CONF file. I've provided an
example below (it also includes call groups and pick up groups - I've
set it so that any group can pick up a call ringing for someone else)
You'll also need contexts in EXTENSIONS.CONF to control how your users dial. The entries in ZAPATA.CONF for the (FXS) extensions will invoke the appropriate context in EXTENSIONS.CONF so that the appropriate trunks are used. Check out the "Dialling a Group" section of http://www.voip-info.org/wiki/index.php?page=Asterisk+Zap+channels for information on the various ways you can have Asterisk select a trunk from a group. I've used r below - a round-robin search, starting at the next highest channel than last time (aka. ascending rotary hunt group).
Yours,
Hugh

Hi,
Without separate incoming and outgoing context you could not secure your
system from an outside caller using your system to dial a long distance
number.
Here is an example outgoing context that restricts who can call long
distance. If a SIP phone does not belong to the 'longdistance' context
they can only make 'local' calls through the ZAP trunk, likewise if a
outgoing ZAP channel is in the 'local' context it can only make local calls:
**Outgoing.incl****
[local]
ignorepat => 9
exten => _9NXXXXXX,1,Dial(${OUTBOUNDTRUNK}/${EXTEN:1})
exten => _9NXXXXXX,2,Congestion(5)
exten => _9NXXXXXX,102,congestion(5)
exten => 911,1,Dial(${OUTBOUNDTRUNK}/911)
exten => 9911,1,Dial(${OUTBOUNDTRUNK}/911)
include => default
[longdistance]
ignorpat => 9
exten => _91NXXNXXXXXX,1,Dial(${OUTBOUNDTRUNK}/${EXTEN:1})
exten => _91NXXNXXXXXX,2,Congestion(5)
exten => _91NXXNXXXXXX,102,congestion(5)
include => local

As you can see above the outgoing context limits which phones have
access to longdistance lines. The incomming context cannot match the
outgoing or you will have on hell of a security problem...
I hope this example helps explain what I am talking about.
Thanks
