[Freeswitch-users] Sending an Event to a Session for onInput

I'm used to using the onInput callbacks inside lua and javascript to listen for dtmf and other events and perform a task accordingly. I'm wondering if there is a way to send an event to a session or channel that can be caught using the setInputCallback inside lua from outside the session program. Maybe an API command that can generate an event for a specific UUID. Does a mechanism exist to do this that I'm over looking? Thanks. --matt
