I posted this response to Asterisk-Users yesterday. Not sure why you didn't
get it the first time.
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

Hello All !!!
I have 4 PSTN lines in the PBX server 1,2,3,4.
First line will be used by only one extension (i.e. for the boss) for incom
ing and outgoing. This line is dedicated for him only.(
The remaining lines will be shared by the employees
1) Group A have access to lines 2 , 3 & 4.
2) Group B have access to lines 3 & 4
3) Group C have access to line 4
I want to know that how i will make that groups.
I will be grateful for ur help.
Thanks a lot.
Faisal
