New Revision: 205471
URL: http://svn.asterisk.org/svn-view/asterisk?view=rev&rev=205471
Log:
Fixes 8khz assumptions
Many calculations assume 8khz is the codec rate. This
is not always the case. This patch only addresses chan_iax.c
and res_rtp_asterisk.c, but I am sure there are other areas
that make this assumption as well.
