Hi folks. There's probably something obvious I'm missing here. When I attempt to change the secondary element of a phone, I get "Current software version does not allow changing a secondary element. Secondary element can only be changed to 'Not Assigned'."
Why is that? And how can I correct that? Do I need to actually blow the phone out and rebuild it? (this would be a PITA for sure.)
Just a little background - we have a cluster of 5 controllers, but only two of these are actually connected to PRIs. The others basically just act as overpriced ATAs for paging and 911. Several of our phones have been originally configured to failover to one of these "non-useful" controllers, so I would like to change them so they actually fail over to a controller that they can use...
TIA,
