La idea detrás del astconf-parser es contar con una función simple pero efectiva que parsee nuestros ficheros de configuración de Asterisk y nos lo devuelva en un array multi-dimensional.
Esta versión soporta la sintaxis estandar de Asterisk, como así también los llamados "Templates". También soporta la instrucción #include ya que es recursiva. Está originalmente diseñada para leer los ficheros sip.conf, iax.conf aunque también es capaz de leer otros como por ejemplo extconfig.conf y res_mysql.conf.
Actualmente este código forma parte del paquete Windows Operator Panel del cual formo parte del equipo de desarrollo. Lo pueden descargar en forma gratuita desde el sitio del Asterisk WOP.
