I have several 7985 and a CUCM 6.1, none of the 7985 registers in the CallManager. The 7985 came with firmware 4.1.4 however i uploaded the new firmware 4.1.5 into the CCM, after rebottin the phones all of hem upgraded the formwar to 4.1.5 however im still gettin a Unified CM Unavailable msg on the screen. any clue on how can i register these phones?

Another test that i did was to do a complete install of CUCM 6 on another brand new serer with no avail, the phones still nos registering, they only upgrade the firmware to 4.1.5.

All phones have a Boot Load ID S0165, 1.5

how did you added the phones? manually or by auto-registration?

are the 85's on the same subnet as other working phones?

are they receiving the config by DHCP?

if you hard code it does it work?

make sure you have proper DNS resolution or use IPs in the CUCM server config for the CUCM group



if this helps, please rate

Dont use autoregistration.

All the IP Phones are on the same subnet and my DHCP is my router, all the other phones work without problems.

I already tried to configure manually the 7985 with no avail.

I have already configure m DNS so i can resolve my CUCM however i use IP.

So far no go, still not registering, when i look at the 7985 status msg, im geting File Not Found: United Stated/7980-tone.xml

As i look in the TFTP Files on the CCM i see the file is IN there.

Any clue?

Yes, in the Cisco Unified CM Administration, under System -- Server, use the ip address of the server instead of the name.

No name in this field, i have only IP address of my server in this field "Host Name/IP Address". Did you change something else ?

No, after reading the log messages of the phone i noticed that it was trying to connect to the hostname of the ccm (and i dont have a DNS) that why i change to ip address and it worked, before that i only upgraded my phone to 4.1.5 and some to 4.1.6 Firmware. check the messages on the phone in order to see whats happenning.
