monitosAsterisk cuenta con una herramienta muy potente que permite monitorizar y realizar acciones en un nivel más bajo de lo habitual: el AMI.

Olle Johannson acaba de hacer público mediante Sineapps, una nueva versión de este interfaz mucho más robusto y fácil de manejar por un cliente. (Recordad que el AMI se diseñó para ser utilizado por aplicaciones y no a mano)

Se han añadido nuevos comandos y eventos que podreis ver en la ampliación de este artículo y que serán añadidas a la versión Trunk del SVN de Asterisk por lo que las versiones 1.2 y 1.4 actuales no serán modificadas.
