asterisk users - May 2005 - MeetMe Announce User feature

I have MeetMe working fine except I have a little confusion over the
"i"
option.  Is that supposed to allow for announcing to the conference the 
recorded name of the individual who is entering the conference?

If so, it's not working in my verions of Asterisk HEAD.  I  am using 
ztdummy because I have no digium stuff onboard.

Everything else works fine.

Is there some trick to getting the announcement of the name of the user 
to be broadcast to all other conferencees?

Thanks,

B.
