Assuming you are trying to use an X100P or Digium TDM analog card, 
you'll probably want to start with zapata.conf entries something like this:
context=inbound-home
usecallerid=yes
signalling=fxs_ks
faxdetect=no
callerid=asreceived
echocancel=yes
usecallerid=yes
hidecallerid=no
echocancelwhenbridged=yes
rxgain=7
txgain=5
channel => 1

The rxgain and txgain values will need to be tweaked to "your" pstn 
lines, and the values will be highly dependent upon exactly how far you 
are from your Verizon central office. Gains that are to high or to low 
can impact how well callerid info is received.

In your extensions.conf, you might want something like this:
[inbound-home]
exten => s,1,NoOp,${CALLERID(all)}
exten => s,2,Dial(${PHONE3}&${PHONE4})

If you start asterisk from the command like (eg, asterisk -rvvvvvvvvvv), 
you will see the incoming callerid displayed on the command line because 
of the "NoOP" statement shown above.
