"outgoing message" would be that feature: IVM places a call and runs it through a (few) OGM(s) ?
But that is only activated on the IVM interface, whats the point in activating it remotely?
If you mean the greeting of mailboxes, i never really tryed that method described, i allways change the WAV file directly, but one way i can think of, going around the mailbox application itself would be something like that:
a 'mailOGM' that plays a greeting then transfer to a mailbox with no greeting (i.e. 0.1 sec mute greeting)
a OGM that transfers to 'mailOGM' if timed out OR to 'adminOGM' if pasword is typed (password would be a single key press --> tranfer to another OGM, followed by a "capture of keys" into a current call VAR)
if VAR differs from password u're transfered back to ogm-1 or to 'mailOGM', if its equal, ure asked to record a file (the same file 'mailOGM' plays)
