In the software download page I can see there suppose to be a new firmware released on May 19th. Now this is not available through Accessory Tool, and the ZIP file actually contains the old 2.2(1.6) version. Was hoping to install this to see if this release will fix the microphone pickup range issue I mentioned in another post.
Solved! Go to Solution.
The current firmware, released on May 19th on CCO is 2.2(1.7). If you open the ZIP file, you will see sunkist-1-6-0-162-EN.bin.ptc, this is the upgrade file that you're looking for. On upgrade.cisco.com/accessories, you will see the same version. Please upgrade to this version.
Just a reminders that you can also upgrade using your mobile app.
Thank you for your support. My mobile does not offer any firmware upgrade and with ugrade.cisco.com/accessories it also says "Your Headset Firmware (1-6-0-162)is up to date.". If I choose to "Load file from your PC" and select the sunkist-1-6-0-162-EN.bin.ptc, which is part of the cmterm-headset.2-2-0001-7.zip file, I get a notification "upgrade.cisco.com says: the local binary firmware version is same as device." and the Start Update button remains grayed out.
So, actually the May 19th released 2.2(1.7) version is the same as the 2.2(1.6) version which my headset already has? Have to say I'm a bit puzzled with your release numbering then... Have to say was hoping for never release especially due the microphone pickup range issue that these headsets have and make them unusable in Webex calls.
