I have a cisco cme 4.1 and I have configured it aparently correctly, the problem is that I have 2 kinds of phones, 7912 and 7940, all 7912 runs correctly but 7940 doesn't register.
Normally it takes IP but in the screen appears the message "File not found"
I have tried to put a static IP address but it's the same. Why could be this?
this is the dhcp config?
Why can I debug it?
no ip dhcp use vrf connected
ip dhcp excluded-address 10.0.0.1
ip dhcp pool ITS
network 10.0.0.0 255.255.255.0
option 150 ip 10.0.0.1
ip name-server 220.127.116.11
ip name-server 18.104.22.168
