Asterisk CallerID look up script for NZ.

It works with by scraping results from yellow pages, where you can feed it a number and if there is a listing that matchs then it returns the company details.


FreePBX Setup

Go to CallerID Lookup Sources and define your own source as following:
Source type: HTTP
cache results: yes ( populates PhoneBook automatically and saves bandwidth)
Host: localhost
Port: 8071
Path: /
Query: [NUMBER]&${CALLERID(name)}
Go to Inboud Routes:
Set the CID Lookup Source to your own source in all Inbound Routes
Internet Services Setup

Since we are using xinetd, put the following in your /etc/services:
asterisklookup 8071/tcp # asterisk lookup
and put the following in xinetd.conf:
service asterisklookup
{
socket_type = stream
protocol = tcp
wait = no
user = asterisk
group = asterisk
server = /usr/local/bin/callerid.sh
disable = no
}
Then restart the xinetd daemon with...
/etc/init.d/xinetd -restart

Create and install script:
#!/bin/sh

Save as callerid.sh, copy into /usr/local/bin and make it executable...
chmod a+x /usr/local/bin/callerid.sh
Make two blank files for the retrieved and unknown callers numbers to be saved, and set the file permissions, and owner to the asterisk user.
echo > caller-id.txt
echo Unknown, Unknown > caller-id-unknown.txt
sudo chown asterisk:asterisk caller-id*
sudo chmod a+rw caller-id*
Done.
