[AsteriskBrasil] AGI - Shell Script

[Carlos Eduardo B. Rovaris]

Boa noite,


Gostaria de saber se alguém tem AGI em desenvolvida em Shell Script que 
poderia me auxiliar em alguns pontos que estou com dificuldades de resolver.


Segue minha configuração:

->>>> Extensions.conf

exten => 500,1,agi(2test.sh)
exten => 500,n,NoOP(${consulta})

############################################################

->>>> Script Shell:

#!/bin/bash

numero=48xxxxxxxx

consulta=  ## procedimento de consulta do valor armazenado na variavel 
numero ##

echo "SET VARIABLE consulta $consulta "

############################################################

->>>> Debug Asterisk console:

Verbosity is at least 20

Basicamente o que estou precisando resolver:
- como armazenar o valor da "agi_extension" na variavel "numero" do 
Shell Script ?

- Como faço para encaminhar a chamada de acordo com o valor de retorno 
da AGI ?

ex: No exemplo do log, disquei 500, e através da AGI retornou o valor "5".

Assim gostaria de fazer:

Caso o valor seja "4", encaminha para Trunk1
Caso o valor seja "5", encaminha para Trunk2
Caso o valor seja "6", encaminha para Trunk3


Agradeço toda e qualquer ajuda.
