Hi I have 2 clusters formed by these servers:
Cluster 1: IP NETWORK 10.10.10.0/24
1 Publisher .1
1 Subscriber .2
1 Tftp Server .3
Cluster 2: IP NETWORK 192.168.1.0/24
1 Publisher .1
1 Subscriber .2
1 Tftp Server .3
I have configured a 7911 in cluster 2 with MAC address.
In the router's DHCP 150 option, I put both the tftp server (10.10.10.3 192.168.1.3) in this order, but the phone rgo in automatic registratio on the firts cluster.
Can i keep this option 150 format and register the phone on cluster 2?
Thank you

What are you trying to achieve here??
If you want the phone to register to two clusters at the same time, that's impossible.

I'm sorry but my description of goal is wrong.
I dont wan't to register the phone to two Call Manager at the same time, i'm asking if it's possible, to put in the tftp file configuration both cluster subscribers.
Follow my example..
I have 1000 branch office and i need to configure the DHCP on their CE but i don't know where phone will be connected..if on Cluster 1 or Cluster 2...
Because CE configuration will be did before, i'm asking if there is a solution for the phone to register on the correct Cluster without change the tftp order in the DHCP.
I'm saying bull**bleep**? :)

Hi Sandro,
If you have two different clusters and an an IP Phone registers (let's say) on Cluster1, it will receive a directory number eg 1000. When the same phone , for some reason, looses connectivity to Cluster1 and registers to Cluster2 it will receive (I guess)the same Directory number but Cluster1 cannot send call to 1000 on Cluster2 because it considers 1000 as local extension for an unregistered device.
A feature that could help you on what you are trying to achieve is device mobility.
Please let me know if I well understood your query.
HTH

Hi Carlo, this is not what i need ..
I do not need a backup ... i need to configure the dhcp on CE without knowing where the customer will configure the phone.
If the customer configures the phone on cluster 2 and in the DHCP the first TFTP is of CLUSTER 1 then the phone will register on CLUSTER 1 in Auto Registration ... i'm asking if there is any way by tftp to recognize where the phone Mac Address is configurated, and send the correct configuration file to phone ..
But i think it's impossible to do, i'm asking something stupid ..
