The CCX 400 runing 1.x firmware is currently unable to upgrade to the 6.2.21 version which Microsoft posted to the TAC. This version will be removed and temporarily replaced with the previous 1.x version to prevent the phones from attempting a failed upgrade.
By the end of the month an updated version will then be posted to the TAC to resolve this upgrade problem.
My contact at Poly suggested the firmware update was supposed to be out on Thursday 24th but has now been pushed back to October as a newer version of Teams is going to be integrated in as well. Any further information on this one?
Hello @FoxPoly ,
Welcome to the Poly Community.
This is correct as our Partner Microsoft discovered an issue and wants to address this via a new APK version of the Teams IP Phone software for Android. At present this is aimed for TAP to be released for the 24/09 and public release around on our public support page at 09/10
If your Poly contact has access to our knowledge base ask him about article 43996
