[asterisk-users] meetme conference using g729?

[Wai Wu]

I have been following this discussion. You do have a point. However, the
way * works right now. If a channel does not require trans-coding to get
into a conference, coder usage is counted. So I really do not know what
difference putting the transcoding in meetme is going to make. I mean,
how could this better contribute to better use of G729 licenses.

Ummm, why??  Unless you can explain some technical reason for this,
looks like about 11 lines to change, +3 for correct log messages, +1 for
a define, +~3 to add it as a nice config option in meetme.conf.

So, in all about... 18 lines worth of code to get it running on any
available codec, configurable from meetme.conf, which IMHO would make a
lot of sense for single-codec systems... especially for G.729 due to
better use of licenses, but for others too, due to load reduction and
improved audio quality...

Of course, I could be missing something obvious, please correct me if
that's the case.
