[Asterisk-Users] Re: RE : Re: RE : codecs order and so on

[Moises Silva]

Ok Oliver, i have been messing arund with this codec thing, and this
may help you as it made it with my problem:
http://bugs.digium.com/view.php?id=4825

I have adapted a patch from the one posted there, so it can apply in
asterisk-1.2.1, you can get the patch here (not sure how much time
will i leave it there):

http://chewbacca.ivsol.net/codec_negotiation-20051107-ivsol0.patch

Unfortunatly i have customized that patch taking the sources from
gentoo ebuild package, and may not apply cleanly in "virgin" sources.

Regards.
