Hello! I have a problem with an internal call staying connected indefinitely. I have 3 remote extensions, and they can call each other as well as make and receive external calls without problems. The extensions are cordless phones connected to FritzBox. I have the Assistant installed on my PC. What I have done is: 1 -- initiate a call from my extension (502) to extension 503 through the Assistant, in MakeCall mode (default). 2 -- transfer the call from 502 to 504 using drag and drop. So now 503 is talking to 504. 3 -- after a while 504 hangs up, but the extension status still shows 503 and 504 as connected. Server log shows Currently active calls - 1:  Any idea about what's happening? Thanks!!
