Hi,
This is CUCM 6.1(1)a. I have 7941 phones that are all configured for the same device pool. They are configured to register to the subscriber and the publisher is configured in DHCP to be the primary TFTP server. When we originally set up the servers and a couple of test phones, we manually assigned the IP address, gateway, TFTP server, etc by unlocking the network settings. Later, DHCP was re-enabled on the phones and they worked fine. Now we are setting up a few more IP Phones, and they are on the same vlan as the other working phones. They get a DHCP IP address from the same vlan as the other phones. In fact all the settings are the same except for the callmanager settings. Instead of CallManager 1 as 10.10.10.2 (active) and CallManager 2 as 10.10.10.1, the phones show CallManager 1 as CISCO-BCD0B887D and CallManager 2 as 10.10.10.1 (active). Although the phones can dial out, the problem is when they press the services button and it says Host Not Found. The server name listed is not even the actual hostname of the server. Does anyone have any ideas on how to fix this? I even tried to create a new device pool that listed only 10.10.10.2 subscriber server as the only server in the cm group and the phones still register only to the publisher.
