CX700 - 7577.4066 FW - DE version



I would like to ask you for help. Could someone send me client update 7577.4066 for CX700, but relase for Germany ( DEU ) ? I have lot of CX700 phones with 3.5.6907.222 (2.1) update release. But these phones, due to old client update version ( CU ), dont want to get new FW updates from my Lync environment. ... here is available just ENG version.


I was trying to get this old version from MS web page. I was also trying to search google. But without any success. All links are directing to latest update 4397.


Thank you for your help
