Problem with 3CX desktop client

[s170]

Hi,
I'm using 3CX desktop client version 18.12.425
Every now and then I have problem with desktop client which manifests like this: when started freshly it works well for several days, then when incoming call comes the client pops up, clicking on answer does not work - no error, absolutely nothing happens and the call is not answered. Also, when trying to make an outbound call it is not successfull, just disconnects the call in second or two.
So the client stops working for some reason (without error) and has to be restartaed and then it works again for several days.
Tried to reinstall but did not help.

Regards,
Drazen

There have been occasional threads similar to this in the past. From memory:

Is this a laptop or PC that goes to sleep and the issue happens after waking up?

Does it happen after the laptop changes networks? (wired to wireless, etc.)

I have one endpoint who says it happens daily (first call in the morning) but their PC doesn't go to sleep and it's a wired connection. I've seen something like this myself but only about every 2-3 months.

It's desktop computer that is turned on 24/7, doesn't go to sleep. It doesn't change networks, it has only Ethernet and it is always connected. We use 10 more softphone clients on other computers, and only that one is having this problem, all the rest work without problems. Is there some kind of logs on the client side that we could look at to see what happens with the client when it has that problem? (I'm talking about problem that dpetrek reported, as it is my computer that is having this issues)

If you haven't resolved this already. We had exactly the same thing, 3CX support were stumped as nothing showing in the logs. In the end we disabled Teams, which then threw up an error within the logs relating to binding to an IPv6 teredo tunnel address. If you disable teredo via GPO it fixed it for us when all the machines were rebooted (or so far so good).

Good Morning Everyone,

i have my window app, for any time i want to make a call, it keeps saying call not found. and it drops within second but the incoming extension call works very well.

how do i go about it. Thanks

Today in the morning I had one client complaining about the same thing. I checked it by myself. Incoming calls where signalled but cannot be picked up. Clicking on pickup just does nothing.
At the same time it was also not possible to make calls. After some seconds outgoing calls where dropped. No ringing tone. Seems there is some connection error between app and server.

Client used the Desktop App for Windows (latest version).
Server is v18 latest RC candidate.

I restarted the app at clients laptop with no success. The only thing that helped was a reboot. After that things went back to normal.

Client uses a laptop. It may went on sleep mode between the days. Anyway this error needs some attention as there is no error code shown. Also no entries in log can be found. Even the outgoing call trials are not in the call log. So I guess there is an issue with the app-server connecion.

Best regards

David
