Strange headset problem on Cisco 7945

[Vadim Semenov]

Hi, All,

strange problem with 7945 occured after rebooting CUCM - "headset" button lit all the time (of course headset is connected) so if call is coming on the IP Phone - you should press "Headset" button twice(!). How it's possible to set the IP Phone or IP Phone profile in CUCM 9.1 that "Headset" button is off all the time in order to if headset is already plug in and i want to answer call - i press headset button one time ( i can press button near the display or soft button "Answer", but it doesn't usable/confortable).

In DN setting auto answer is OFF.

Hi Vadim,

What is the firmware version of the IP phone? You may want to check the following bug
