Rick Varvel, Microsoft Consulting Services comes through with another great paper. I mentioned his papers for the Edge Server in the past and he has now dedicated time to the OC Phone Edition (OCPE, Tanjay) upgrade process.

Due to some of our programs purchasing devices in advance of program needs for budget reasons we ended up with multiple firmware versions. In fact we even had devices with the .199 build for which Rick was testing with.

Here is the text of his blog and url -

 

    This document provides best practices for upgrading an OCPE device (Tanjay) from build 199 to 522 and then to 6907 using just the Office Communications Server 2007 R2 (OCS 2007 R2) Device Update service.
    For those familiar with the process, there is a high level walkthrough in the “OCPE Device Upgrade Steps (Summary Version)” section; otherwise the detailed process begins with the Step 1 in the “OCPE Device Upgrade Steps (Detailed Version)” section.
    Also included:
  • Background information on how the different Tanjay firmware builds behave during the sign in and download process to assist with troubleshooting
  • Environmental dependency settings for DHCP, NTP, certificates, and DNS
  • Pool configuration changes required to successfully sign in and upgrade a Tanjay
  • Syntax examples and a sample scenario to simplify the deployment process
  • A sample NetMon trace file highlighting a successful sign in and upgrade
  • Log file locations and URLs used in troubleshooting common issues
  • An Appendix with step by step instructions for many common tasks
