3cx API and powershell

[webturtle]

Good morning.

I use a powershell script to monitor the status of my trunks, because i have an issue with my firewall and have to empty its connection table after a reconnect sometimes.

The thing seems to work, but one small problem:
I can only connect to 3 CX from one version of the script. A second connect is only possible after a reboot of the server.
For example:
I try to develop the script in the Powershell ISE and everything works.
If I start the script as a service, i get a not connected error.
If i reboot, the service works.

If i restart the service or have to change something inside the script after some days, i have to reboot the server.

I cannot figure out how to disconnect cleanly.

Here is the 3CX Part of the Script:

$3CXInstallDir=(Get-WmiObject -Class Win32_Product | where {$_.name -like "3cx*Phone*System*"}).installLocation
        
    [void][System.Reflection.Assembly]::LoadFile("$3CXInstallDir\Instance1\Bin\3cxpscomcpp2.dll") 
    [void][TCX.Configuration.PhoneSystem]::set_cfgserverhost("127.0.0.1") 
    [void][TCX.Configuration.PhoneSystem]::set_cfgserverport("5485") 
    [void][TCX.Configuration.PhoneSystem]::set_ApplicationName("CallViewer") 
    [void][TCX.Configuration.PhoneSystem]::set_cfgserveruser("cfguser_default")
    [void][TCX.Configuration.PhoneSystem]::set_cfgserverpassword("**********")
    
    $global:My3CX = [TCX.Configuration.PhoneSystem]::get_Root() 
    
    $global:Tenant = [TCX.Configuration.PhoneSystem]::Root.GetTenants()
    
    if (( $Tenant[0].GetExternalLines() | where {($_.Number -eq "10002") -and (!$_.IsRegistered)}))
        {
            echo Nicht-Registriert

            cd "C:\Program Files (x86)\PuTTY\"
            Start-Sleep -Seconds 30
            .\plink.exe "does a command to empty the connection tracking in my firewall"

        }
        else
        {
            echo Registriert
        }

    #$My3CX.Disconnect()

I tried the disconnect command, but that freezes the whole thing and after that a reconnect is not possible.

That is some bad a$$ code. Would you consider posting and sharing? With some community involvement and testing we could probably get that figured out and extended.

Nice work.

What exactly do you mean?
What shall post in addition?

If you mean the whole Powershell as a Service thing, it is here:

Inside this script a added a function Connect_ToPBX which holds the above code.
