<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Need help regarding video conferencing setup. We
will have 8 site (including head office). The minimum bandwidth per video call
will be 512 kbps. The connections are T1 lines. Currently we have IPSec
VPN with overlay routing over the internet for data. So how do I
calculate the bandwidth for each site if all sites do conferencing
simultaneously.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My rought estimate is: </FONT></DIV>
<DIV><FONT face=Arial size=2>512k + L3 + L2 + IPSec + GRE</FONT></DIV>
