[cisco-voip] Registering a hardphone to a different CCM cluster

[Wes Sisk]

leave dhcp enabled.

setttings->3, **# to unlock
32 (Alt TFTP) ->yes
8 (tftp) edit, save  phone reboots, downloads config file from new server,
registers to new cluster.

only time this hasn't worked for me:
1. TFTP server is down (troubleshoot the CM server)
2. device encription and authenticaion is enabled on the phones (cm4.x, usb
keys,....)

Hello,

Does anyone know the secret to forcing a phone to register to another CCM
cluster on the same subnet?

We have one CCM cluster, running TFTP on both CCMs, to which our DHCP server
points new phones (via the 150 option). Sometimes I would like to switch a
hardphone (i.e. 7905) from this cluster to another separate cluster.

To do so, on the phone I disable DHCP and change the TFTP Server 1 value to
the other CCM. And when I validate, it restarts the phone and 50% of the
time, the phone registers with the other CCM. 50% of the time it stays with
the original CCM, regardless of the new settings. In such a case, the
network settings on the phone still have the correct TFTP and DHCP settings,
but the Call Manager settings are still set to the original CCM.

I would like to find a way to force my phone to register with the new CCM.
Is there a way other than changing the TFTP settings? By the way, I've tried
turning off the TFTP service of the original CCM, which works. However I don
't always have access to that CCM.


Thanks,
Paul
