According to
http://www.voip-info.org/tiki-index.php?page=Asterisk%20timer%20ztdummy
, ztrtc is supposted to fix the MeetMe delay.  It compiles by default on
Linux 2.6 with newer versions of -HEAD.  To get it on 2.4, I'm not sure.
 I know there are some discussions about this on the bug tracker too.
