[SOLVED]3CX Phone not working with VPN active

[DGutschalk]

Hi,

I am having some issues getting my 3CX for Windows 12 Client to work.
I have a home office desktop, if I start 3CX and let it connect to the public IP adress it will work.
If I activate my VPN (need that for outlook) 3CX fails to start with the following error message.

3CXPhone for Windows has to be closed because of an internal error. You can find the details about this error in C:\Users\sadsad\AppData\Roaming\3XCPhone for Windows\Logs\3CXPhoneForWindows.log
Please submit a support ticket with this log file to http://support.3cx.com

The log file shows this

Re: 3CX Phone not working with VPN active

That depends on how your VPN client is being setup. If its in tunnel all mode, your sys admin may restrict where your traffic can go and that may prevent your 3CX phone to talk to the 3cx server. If your company's email server is on the same subnet with the 3cx server, all you have to do is to enter the 3CX server LOCAL ip address to your 3cx phone "Out of office" field. It will attempt to connect to your server "locally" once you're on your VPN.

Re: 3CX Phone not working with VPN active

It's odd that it mentions a couple of headsets in the log. Are you actually using one of those brands?

If you come to dead end with everything else, perhaps try setting the audio device as the computers speakers, no headset, and see if that makes a difference. If it starts up without the error, it would sort of narrow down the cause.

Re: 3CX Phone not working with VPN active

Hi,

One of my colleagues was able to solve this problem by moving the %appdata%\3CXPhone\ .xml files, starting 3CX, moving the .xml files back and starting 3CX again. I don't know how this is a workaround or solution for this error but in my case it fixed the issue.

Thank you both for replying to this thread

There may have been some corruption on the initial install. Did you ever try removing, then re-installing?

 

[DGutschalk]

Of course I did that. I did not check though if all files were removed.
