Cisco 7841 Distinctive Ring

I’ve been Googling and searching the forums here for the past hour or so and can’t seem to find an answer. I was wondering if anyone has experience implementing Distinctive Ring via Alert Info on the Cisco 78xx series? I have a 7821 & 7841 and would like to have different rings for queue calls vs normal internal calls. I’ve tried various things in the alert-info box such as Chirp-2 and but these don’t seem to do the trick. Ideally I would like to have Chirp 1 play for internal calls and Chirp 1 also play for queue calls, but with a double ring rather than a single.

Just wondering if anyone’s managed to do this?

Kind Regards
