Sistema telefonico de consulta meterologica basado en Asterisk & Yahoo Weather

Aquí usaremos Asterisk & PHP  para crear un sistema de consulta del clima atreves de nuestra central telefónica. El Sistema verificara el Caller ID de la llamada y en base al código de área del numero que esta llamando nos dirá las condiciones climáticas para esa ciudad.

El sistema cuenta de  2 archivos en PHP:
YahoWeather.php
YahoWeather.class.php

También usaremos el TTS de Asterisk para que nos reproduzca el nombre de la ciudad y así evitar grabar los sonidos para los nombres de cada ciudad del mundo.

Custom ringtone on calls from queue

by malcolmd » Fri May 31, 2013 6:58 am 

Code:

exten => 200,1,NoOp()
same => n,Answer()
same => n,SIPAddHeader("Alert-Info: <ringding>")
same => n,Queue(sales-queue)

Asterisk 11.4-ish

I dial 200, I hear my ringding ringtone, which is not the default ringtone for my phones, on each of my called phones. It works for both permanent Queue members (defined statically in queues.conf, e.g. SIP/101), as well as login/logout members who've logged themselves in via the Queues app on the phone.

How to remove Asterisk

it is sometimes necessary to completely remove Asterisk for one machine, for example because you need to install a newer version.

Stop Asterisk and unload its modules
The first thing you have to do is to stop Asterisk and unload the modules it may be using, e.g Zaptel's.
The following lines will brutally terminate Asterisk and kill all ongoing conversation. You have to kill safe_asterisk first, otherwise it will respawn Asterisk.

killall -9 safe_asterisk
