To be more exact, you need one DAHDI channel of *some kind* per caller.

For DAHDI hardware channels (e.g. PRI), Meetme can mix directly from
the channel and doesn't need a pseudo too.

For VoIP channels (and a few other cases), Meetme needs to route the
call through a DAHDI pseudo channel to give it data to mix.

And yes, two pseudos per meetme - one for recording from and one for
playing announcements into the conference.
