I have a large range of phones (7905's, 06's, 12's, 40's, 60' etc). The problem I have is that all the new 7940's get the wrong TFTP server and the wrong Call Manager IP address - all other new phone types are fine! I have only one tftp server, and one dhcp server (on the same box). All the other settings issued from DHCP on the 7940's are correct (except for TFTP/CCM). I have DHCP options 66 and 150 configured on my TFTP server.
Version of CCM is 4.1(3)sr4d.
