SV8100 phone system with UC Desktop installed.

When you make or receive a call by a soft phone within UC Desktop, "Active Call" continue counting when the call is end.

But the line has been released, it looks like just the UC Desktop is not working properly.

It never happens on a digital phone in the same system.

Database and data capture by Wireshark has been sent to NEC, but no reply yet.

Any suggestion?

Yes, only soft phone.

It might only be UC desktop.

Sound like a software issue just on the softphone. Are you using CAP keys?

You are using PSTN trunks or digital trunks ?

If you are using PSTN, check 14-02-12, Detect Network Disconnect Signal and 14-02-18, Busy Tone Detection on Talking

Test it.

We called NEC so many times, and sent phone system database, shared services configuration, Wireshark Capture to NEC, but no good news yet.

Today, we recreated a new database for the phone system and put it in, first 2 UC Desktop+softphones were working perfectly. But when we started to put the rest 3 in, none was working, even the first 2.

then we re-installed the UC desktop, no good. then re-installed the shared services, no good.

Once we thought it might be the license issue because it had 2 "0112 third party CTI client" in the phone system. So we turned 10 days temporary license on, issue remained. NEC tech said 0112 should just be "ON/OFF", 1 should be enough.

So we have no idea what's wrong.
