asterisk users - Jan 2006 - how do i play a prerecorded message in the middle of a conversation ?

as the subject says, suppose i want to do the phone-equivalent
of cut&paste on a messagging program, i.e.
play back a prerecorded file in the middle of a conversation,
is there anything that lets me do the trick by working
on the dialplan, or i should go and write my own res_features
trick ?


Ideally i would like to come up with something like
dialng *5xxx where xxx is the message number i want to
playback.

	cheers
