I would check your IIS logs for assistance with the device update troubleshooting. Here's the process that the devices use:
How Devices Obtain Updates from Device Update Service
Device Update Service supports two UC devices: Office Communications Server 2007 R2 Communicator Phone Edition and RoundTable. RoundTable must be manually configured to connect to the Device Update Service, as described in Appendix D: Configuring RoundTable to use Device Update Service. In the default configuration, Communicator Phone Edition connects to Device Update Service in the following manner:
- The first time a user starts Communicator Phone Edition and signs in, the device gets in-band provisioning information from the server or Enterprise pool hosting the device user account. The information contains the internal and external URL of the server running Device Update Service.
If the device is turned on, but no user signs on, and no user has ever previously signed on to the device, the device sends a DNS lookup request to ucupdate.R2.<SIP domain> and obtains the internal and external URL of the server running Device Update Service.
- Thereafter, when the device is turned on as well as every 24 hours by default, Communicator Phone Edition checks for updates by sending an HTTP request over port 443 to the Web Components Server hosting Device Update Service. The request includes the current version that Communicator Phone Edition is running.
- Device Update Service returns a response containing one of the following:
- If no approved updates exist for the current version of the firmware, the response contains downloads=0. For test devices, updates must be pending rather than approved for this to occur.
- If an approved update exists for the current version, the response contains an internal and external URL for Device Update Service. For test devices, updates must be pending rather than approved for this to occur.
- In the latter case, Communicator Phone Edition sends an HTTPS update request over port 443 to Device Update Service.
- The update image is downloaded to the device.
- The device waits for five minutes of idle activity, and then restarts to complete the update.
