What i want to do is have one asterisk server connected to the switch(gr-303) passing calls . Then use asterisk servers at customer locations to handle voice and data either over a data t1 or voice and data t1. Can asterisk be used as a concentrator? If so how is best used? Using data t1s and everything go into the asterisk server as voip and get passed to gr303 then to the switch, or channelizing a t1 using some for data, some for voice into the asterisk back out the gr303? <BR></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Brian Haynes</FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">MountaiNet Network admin</FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Icq 2238953</FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">MountaNet blog <A href="http://webmail.mounet.com/blogs/MnetBlog/">http://webmail.mounet.com/blogs/MnetBlog/</A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Times" size="4"><SPAN class="Apple-style-span" style="border-spacing: 1px 1px; font-size: 16px;; border-spacing: 1px 1px; font-family: Times; ; border-spacing: 1px 1px; "><SPAN class="Apple-style-span" style="border-spacing: 1px 1px; font-family: Times; font-size: 16px; ; border-spacing: 1px 1px; "><SPAN class="Apple-style-span" style="border-spacing: 1px 1px; font-family: Times; font-size: 16px; ">Engineers aren't boring people; we just get excited over boring things.</SPAN></SPAN></SPAN></FONT></DIV><BR class="Apple-interchange-newline"></SPAN></SPAN> </DIV><BR></BODY></HTML>
