DAHDI is required for MeetMe to do the audio mixing.  ConfBridge does not
need DAHDI since
it does its own mixing in Asterisk.

As for timing sources you have several to choose from of which DAHDI is one
of them.  See
menuselect res_timing_xxx modules.  Timing is really only needed when
playing back sound
prompts when nothing is being received.
