One Client keeps disconnecting/reconnecting

[ssteelman]

For the last 3 weeks one client of ours has been having issues with their on premise server showing "disconnecting...reconnecting in XX seconds" or a call just hanging and us having to force a reboot. Server is on V20, vmware hosted with debian v12. I have also noticed something strange that the system seems to continue to call out to +11234567899 repeatedly and getting a 503 service unavailable response from the trunk. This is our only system on v20 right now. None of our v18 systems have the disconnecting issue or see the calls out to +11234567899. Anyone have any ideas of what I can check?

System has 4 CPUs, 8GB ram with 500GB drive.

Have you checked at that point if all 3CX Services are up and running?

I have also noticed something strange that the system seems to continue to call out to +11234567899 repeatedly and getting a 503 service unavailable response from the trunk.

Is there any configuration or a CFD project that might cause the issue?

I did find out that the +11234567899 was a mobile number put on an ex-employees extension and was set to ring mobile as well so fixed that half but the server is still going to disconnected pretty often. And it comes right back online after about 30 seconds.

I dont think it's going down or anything as we don't have to log back in when it reconnects.

You never mentioned what the conditions were going back further then 3 weeks.

Was they on v18? Has it been like this since install?

Have you tried running a continuous ping to the 3CX?

Have you checked vmware event logs?

Call hanging - What are the symptoms? Is this an active call? could be a timing issue...

Have you also confirmed that the machine has the required hardware specifications based on the amount of extensions?
