[cisco-voip] IP Phone Keep Looking old CCM

[Adam Frankel]

Check the phone's web page, particularly the "Status" section for any DNS or
TFTP timeouts.  This might give some clue.

 

The behavior you are describing sounds similar to if the phone got its
config file from the new CCM which referenced the CCM server by name which
was not resolvable by DNS hence it registering to its cached CCM.  Then once
you shut down the 4.1 server, it resets and the same process occurs but
instead of registering to its previously cached CCM, it registers to its
TFTP server.

 

You can get the config file yourself to verify if it is using DNS:

 

tftp -i [tftp server] GET SEPXXXXXXXXXX.cnf.xml

 

Check what is listed for the callmanager name, which is pulled from the
processnode name in CCM:

 

"run sql select * from processnode"  or System->Server

Do you have secruity enabled?  If so, you have to updated CTL files to make
the 6.1 TFTP address a 'valid' TFTP provider.

Hi, i had my 4.1 CCM replaced by a 6.1 CUCM.
the old one is still running since it has co resident a CRS with an AA.
I use a trunk to send calls to new 6.1. That works fine
In my DHCP pool, i have the tftp option changed to point at 6.1 IP but, the
phones even though they have the new option for the TFTP (CUCM 6.1) They
keep register at old CCM 4.1!!
Only if i shutdown CCM service at 4.1, the phone after a timeout, it
registers to 6.1.
If then i turn again on the CCM service at 4.1, the phone does not register
back to the 4.1.
But, if i reset the phone, it goes and registers back to the 4.1!!
I do not use DNS but both CCM have the same name.
Could this be a problem even though i do not use DNS?
how about a factory reset to all phones?

Because when i plugged in a brand new device, it got registered directly to
the 6.1.
So it has something to do with the "memory" of the old devices.

Thanks
Anthony
