<P><FONT SIZE=2 FACE="Arial">As there has been interest expressed in conferencing applications on the Asterisk-biz list of late, I thought I'd draw attention to our CNX conference bridge appliance, which supports up to 120 concurrent users over VoIP or TDM links. More information can be found here: </FONT><A HREF="http://www.aastra.com/enterpriseip/pro_238.asp"><U><FONT COLOR="#0000FF" SIZE=2 FACE="Arial">http://www.aastra.com/enterpriseip/pro_238.asp</FONT></U></A><FONT SIZE=2 FACE="Arial">, but the main highlights are these:</FONT></P>

<P><FONT SIZE=2 FACE="Arial">Note that this is not just an out-of-the-box Asterisk implementation -- we have created a tailored package containing Asterisk, other open-source applications, libraries and supporting frameworks alongside our own custom application to provide a complete, read-to-run conferencing platform. (For developers, source code is of course available per the terms of the GPL, LGPL and other open sources licenses included in the product documentation).</FONT></P>
