Hi Toe,
When you mention adding the new firmware, was it via a new Device Pak?
If so, you would need to schedule a time to give this a try. There is a need to ***reboot when adding support for a "new" device type;
Procedure
NOTE: Apply this patch to all of your Cisco CallManager servers, beginning with the publisher server and TFTP server.
**When applying this Device Package to enable new device support, a cluster-wide reboot is required for those devices to register successfully. A clusterwide reboot IS NOT required when running to update existing firmware/support.
If installing on a Cisco Unified CallManager version earlier than 4.1(3)sr2, the following message will be displayed: “Install on all nodes is required. All nodes will be rebooted as part of the installation.
If installing on Cisco Unified CallManager 4.1(3)sr2 (recommended), the following message will be displayed: "Install on Publisher and TFTP server is required. Installation on all nodes is highly recommended." ***A clusterwide install/reboot is required.
From these older Device Pack Notes (this would be for your DevPak as well

Hope this helps!
