<DIV><FONT size=2>This worries me. We just had a talk with Cisco and they
said as long as you open only the ports you require and use CSA and AV you
should be Ok. We haven't opened things up to the Internet, but it will be a
campus allowance. We want to begin using IPC and other hardphones that don't
have CDP.</FONT></DIV>

they were able to take control of the server through a buffer overflow we
think and disabled these services). Perhaps CCM5 would be better
suited for this purpose, or you could use your pix to only allow the
necessary ports.<o:p></o:p></SPAN></FONT></P>

have Call Manager and Unity hosted in Data Centre. All our clients have
VPN connection to Data Centre. I am using PIX 515 at Data Centre and
PIX501 at clients side. All are working perfect except voice quality issue
some times. Since this is PBXL hosting service and security is not that
much concern, I am wondering I can setup phones to acess CCM and Unity
over the internet using gloabl IP address on Cisco IP Phones. Has anyone
every implemented CallManager and Unity over internet? Your comment and
advice would be greatly appreciated. <BR><BR>Best
