<DIV><FONT face=Arial size=2>Hi Robert,</FONT></DIV>
<DIV><FONT face=Arial size=2>Thank you for your reply. I have already
configured PIX to PIX implementation betwwen PIX515 and 501 but reduce the cost
and impreve the bandwidth at client site, I am thinking about use PIX515 at
Data Centre side and assign global IP address on the phone at client site. But
this way I need some sort of NATting on our datacentre PIX515. it would be
great help if you could send me some reference config for the NATting
implementaion for CallManager environment.</FONT></DIV>

<DIV><BR></DIV>I have done this with a simple PIX site-to-site tunnel and,
yes, the CCM / Unity DOES support NATing. If your scenario is more than
a handful of remote users, like this site was, I would go with the Proxy setup
as Matt described. However, if you have a simple setup and want to go
the site-to-site tunnel route, email me offline and I can send you some
reference configs of the PIXs' and VOIP GWs. <BR><BR>

<DIV><FONT face=Arial size=2>Thank you for your reply. If I do this with
PIX, I guess I have to do natting. I am just wondering whether CCM and

Proxy? </FONT></DIV>

implemented a callmanager/unity directly on the internet in the past for a
company in your same situation. Their server had more worms in
viruses in 1 week than I've seen in my whole life (even with CSA & AV,
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. </SPAN></FONT></P>

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.
