<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">I would like to point out that G.722 is a really awesome codec for wideband. Asterisk has some changes that will need to be made to support variable audio rates. We did this in FreeSWITCH from the start. I think Asterisk will be doing similar things to bridge an 8k to 16k channel via resample. FreeSWITCH can already do this so you could use FreeSWITCH in conjunction with Asterisk to solve this for now. FreeSWITCH can also do Wideband conferencing. In addition you can mix and match 8k and 16k conference participants. Just thought I would throw that out there as a way to bridge the gap.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>/b</DIV><DIV><BR><DIV><DIV>On Oct 5, 2007, at 1:13 AM, Ondrej Valousek wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Hi Kevin,</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Thanks for the answer - Hopefully this feature will be available some</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">day.
