#!/usr/bin/env python
""" Simple python server to allow Remote phonebook of ST2030 to work with
    Asterisk server, using the phone and fullname settings of the config file
    as input values, like
    [20012]
    fullname=Rick van der Zwet


    In order to get it working alter HOST and PORT to the location of your webserver

    Next specify remote phone book URL to be http://HOST:PORT/search?q=#SEARCH
    at Advanced -> Phone Lists -> Remote Phone Book in the webinterface

    OR

    In your autoprovising files the entries under the section [sys]
    Phonebook1_url=http://HOST:PORT/search?q=#SEARCH
    Phonebook1_name=example.com phone book
