The following guide provides a basic setting to detect the caller ID on a standard BT line using the following cards: Digium AEX800 Digium AEX2400 Digium TDM410 Digium TDM800 Digium TDM2400

1. load the module wctdm24xxp with the option opermode=UK for example into /etc/modprobe.conf put the following string:

   options wctdm24xxp opermode=UK
   install wctdm24xxp /sbin/modprobe --ignore-install wctdm24xxp && /sbin/ztcfg

2. zaptel.conf file for a card with only one fxo module:

   fxsks=1
   loadzone=uk
   defaultzone=uk

3. zapata.conf file example:

   [channels]
   group=1
   context=incoming
   echocancel=yes
   echocancelwhenbridged=yes
   rxgain=0.0
   txgain=0.0
   signalling=fxs_ks 
   usecallerid=yes  
   cidsignalling=v23
   cidstart=ring
   callerid=asreceived
   callwaiting=no
   channel=>1
