[cisco-voip] UCM - CUBE trusted IP address

Hello Group

we run a CUCM Cluster 9.1(2) with a SIP Trunk (CUBE) to our telephony
 provider.
Our cluster has 8 Servers (1 Pub / 7 Sub).
On the CUBE we have three dialpeers pointing to three different subs for
redundancy:

dial-peer voice 1000 voip
destination-pattern
session target ipv4: Server5

dial-peer voice 1001 voip
destination-pattern
session target ipv4: Server4

dial-peer voice 1002 voip
destination-pattern
session target ipv4: Server3

On the UCM we have a SIP Trunk configured with a device that contains
Server3, Server4 and Server5 in its CUCM Group.
All IP Phones register to Server4 or Server5.

We now have the problem that Server4 has sometimes a pretty high CPU load
(Code yellow).

I want to change the dialpeers on the CUBE so that they point to Server7
and Server8 to reduce the load on Server4.

What do we have to change on the UCM if we change the dial-peer voice 1000
and 1001 on the CUBE to
dial-peer voice 1000 voip
destination-pattern
session target ipv4: Server7

dial-peer voice 1001 voip
destination-pattern
session target ipv4: Server8

Thanks a lot
Regards Reto
