Define two TFTP Server on DHCP Voice VLAN [CUCM/CME]

[aelankoud]

Hi All

We installed CUCM and CUCM in the same LAN network, currently the IP Phones configured in CME, then I want to migrate the IP Phones one by one, I remove it from CME and I add it to the CUCM, so, my problem when I configure the IP Phone to CUCM, it can not retrieve its configuration from last, because option 150 in Voice VLAN DHCP server, takes @ CME,
My question: is it possible to define 2 option 150 to the DHCP server, @cme and @ CUCM, if the IP Phone still added to the CME, it will retrieve its configuration from it, and the same for CUCM?

Thank you for your helping.

You can define multiple TFTP servers, however the phone will only use the secondary server if the first is unavailable. One option would be to configure an ACL that would block traffic to the primary TFTP server once the phone has been moved. This would be fairly cumbersome as you would need an ACL for each phone as they are moved. Any reason you could not get all phones configured on CUCM and then move all at one time?
