Hello everyone, for more than one year now we are having the exact same problem as stated in this thread (which is locked for whatever reason...): https://www.3cx.com/community/threads/strange-behavior-3cx-client-dials-wrong-number.48001/ When calling any number using the Windows Client in CTI mode there is always the action of the first function key dialed. We are using the current 15.5 Update 2 release and our Snom 710 phones are using the default provisioning template. Like the person of the other thread I can confirm this by looking at the HTTP request sent by the 3CX Windows Client when dialing the number "1337": Code: GET /command.htm?key=P1,10,2000;1;3;3;7;ENTER We have worked around this bug by setting the first function key to line on all our phones. But when using the new Hot desking feature the first function key is always set to the logout dial code. This means that whatever number we call using CTI mode the identity of the user gets logged out. Is there any way this bug can be fixed in an upcoming version?
