IP Phone automatic change ICP1 address

[mitelfang]

Hi guys!
In my network has three ICP composition Cluster,that managed by EM & OPS.
Now all the local IP Phone automatic set its ICP1 IP address to remote office's ICP controller.
So once local ICP restart,all phones will stop at waiting PIN screen.
Even I set static IP,IP Phone also automatic change ICP1 address.
I can see the setting on IP phone,cur ICP IP address is local ICP,but ICP1 IP address is remote office's ICP controller.

I believe what's happening is that because of the IP options in the scope the phone is expecting to be resilient. When the phone looses connectivity to the prime 3300 because of network loss or ICP reboot, the phone registers to the secondary controller. Since the phone is not resilient, the phone doesn't know what it's extension number should be on that controller so it hangs there waiting for you to tell register it to the new controller.
Easiest way to resolve is to make the phone fully resilient via OPSMan.

Do the phones re-home to the local ICP once it is back up? Not sure of the issue. If the primary controller is out of service and the phones aren't resilient they won't work until the primary is back in service.

There may be no i in team but there are three f's in fudge off.

hi dryaquaman
i have checked the OPS?the secondary controller is blank.

hi LoopyLou
the phones not re-home to local ICP,unless restart the phone.

ok, do you have more then one IP address programmed for the RTC in your DHCP options? Am curious why it is homing to secondary when it shouldn't know there is one.

hi LoopyLou
i did not find any other RTC address.
i think this issue maybe caused by OPS,but i do not how.
