	True. But lots of users already have music for hold encoded in MP3.
Converting it to native formats eats either storage space or CPU (on the
fly conversion). And prohibits using streamed radio, like from a central
LAN server, without extra conversion CPU.

	Does the current discussion indicate that Asterisk is moving away from
supporting MP3 for MoH in future releases? Or just sticking with an
obsolescent mpg123?
