for this to be done,
you must define two "Cisco Unified CM Group"
& define two "Device Pool"

in one "Cisco Unified CM Group"
put CUCM Pub first in Selected Row
and put CUCM Sub Second..

in other "Cisco Unified CM Group"
put CUCM Sub first in Selected Row
and put CUCM Pub Second..

then in one "Device Pool"
select the "Cisco Unified CM Group"
which has CUCM Pub in first selected..

and in other "Device Pool"
select the "Cisco Unified CM Group"
which has CUCM Sub in first selected..

at the final,
assing "Device Pool"
to your phones..

half of them
assign then one has which has CUCM Pub in first selected..
and in other half >> assign then one has which has CUCM Sub in first selected..

+ >> on DHCP option of TFTP (150)
on half of them >> set first to ip address of CUCM-PUB, and second to ip address of CUCM-SUB
on other half >> set first to ip address of CUCM-SUB, and second to ip address of CUCM-PUB..
