Announcement to Voicemail without hearing Voicemail Message

OK, I’m stuck.

I want to have one voicemail extension ‘receive’ a messages from different sources. Let’s say extension 123 exists with normal voicemail. I’d like to create one or more announcments (outputs of an IVR) that play a different message, and then the destination would go directly to 123’s voicemail WITHOUT playing the normal 123 voicmail message.

Any ideas?

Thanks,

Mark
