beeping every 2 minutes

[Kinne]

Hi,

I obviously changed something 2 weeks ago.
Since then some users complain about a beeping tone they get when they are calling someone. This (double) beeping tone repeats itself after 2 minutes.
phone is IP Touch 4028 EE. OXE has release 9.0
Well, how can I deactivate it?

What about phone feature COS - item "beep on external calls"?

That´s it. Thanks!
