I am just curious to know if 7940 is supported with CME 3.3? When i try to add load 7940, there is no option for 7940 phones.
How are things my friend :) I think the command should be;
The Cisco Unified IP Phones 7940 and 7940G and the Cisco Unified IP Phones 7960 and 7960G have the same phone firmware and share the 7960-7940 keyword.
Router(config-telephony)# load 7960-7940 P00303020209
Hope this helps!
PS: I'm sure these sets have been supported since at least 3.0
