Is the standby callmanager server by any chance your tftp server?

Are you using DNS in your network?

Did you set the callmanager servers to their IP address?

What does the status message on the phone say?

I ran into a problem where the customer was using DNS and the DNS server entry was not in the DHCP scope.

The phones will attempt to register with TFTP server if they cannot talk to any of the callmanagers.

if the dns don't work, verify host/lmhost and avoid wins.

if these additional ip don't work, check the event logs on the apps side

is tftp turned on for all ccm or just the pub. You can turn off tftp on all the other ccm and just leave it on the pub.

if that still doesn't work, tftp ultimately gets its settings from ccm sql database so you may need to look at that.

hi

i set up ccm group

the backup ccm is sql publisher

the active ccm is subscriber

and only sql publisher turn on tftp server

i also use dns server to reserve ip address

but the same scenario to all ip phone

i don't know why some of them regist worng

turn on tftp tracing to "detail" on the tftp server. You should see the trace picking up a cnf.xml or a default file with the mac address of the phone.

Next, verify the file which is in memory with 3.3 (or 3.2?? and above) so you may need to turn off caching under serv>tftp>advance

then you would see the files in the tftp directory. open it up to see if it matches your ccm config.

also run dblhelper on only the pub for happy faces.

Are the different phones in different networks? If so they are being served different dhcp scopes. Check your dhcp scopes, look for the dns server entries.

In the ccmadmin page, go to system -> Server, is it set to the name of the machine or an ip address.

On the phone go to Settings and check the status messages.
