I am new entrant to cisco voip solution. I bought a cisco approved HP server and call manager 4.3 DVD pack (which has more than 20 dvd's). And firstly started with hardware detection dvd, i have read forums and blog usually it fails and gives an error if the part number of the server doesn't matches but in my case it went smooth and nice there was no problem on it. after completing it asked for ip address, computer name,product key, workgroup and timezone. After that it created some image and showed a display "insert dvd install OS_DVD 3 and it will continue automatically" but i tried with all the DVD that came with the call manager 4.3 package but none of them works and didn't continue the installation.
Any one have suggestion on this..
