I would like to implement IP-Telephony using Cisco UC-520 router. In our Existing Infrastructure we have ISA server 2006 as Gateway and Router also as firewall between the Internet and the LAN
Now I would like to place UC-500 between Internet and the ISA server. Since I do not have POE switches on my existing LAN. I planned to directly connect the IP phones to UC-500(This will bypass going thriugh ISA). This would work fine. But my problem is, We are going to use the IP Communicators in our LAN systems which has to pass through the ISA server and reach CME. can anybody give me idea about making this happen?
Or suggest me if there is any better design for this... Thanks
