I am working on an installation with 9608 phones. The IP Office is on release 8.1(52). I am using my laptop as the HTTP server for now (it is a UCM, so no voicemail server). The customer's DHCP server has been loaded with Option 242 MCIPADD=<IP OFFICE IP>,MCPORT=1719,HTTPSRVR=<MY LAPTOP IP>. There are no vlans on this network, everything is on the same subnet. When I boot the phone, it grabs an IP, downloads firmware files, but then fails to "Discover <IP OFFICE IP>". I can ping the IP Office from my laptop (connected via the network) so I know the IP Office is on the network. The phone is getting a valid IP address on the same subnet. Any thoughts?
