Legacy 3CX Windows Client in 3CX v20
#1 Have 3CX client running works perfectly inside and outside of the office (using both direct-SIP and the tunnel). When users connect via VPN (split tunnel) the 3CX client has major issues:Setup:3CX server - no 3CX SBC.Here's the logical flowIn the office (No VPN): 3CX client -> pbx.domain.com -> 3CX Server Internal IPNo issues to report - everything works fine.Out of the office (No VPN):3CX client -> pbx.domain.com -> External IP -> NAT -> 3CX Server Internal IPNo issues to report - everything works fine.Out of the office via tunnel (No VPN)3CX client -> tunnel encapsulation -> pbx.domain.com -> External IP -> tunnel decapsulation -> 3CX server Internal IPNo issues to report - everything works fine.Out of the office (VPN):3CX client -> Cisco VPN encapsultation -> Internet -> Cisco VPN Concentrator -> pbx.domain.com ->3CX Server Internal IPThe PCAP shows that once encapsulated in the Cisco VPN, it resolves the internal IP correctly and registers with no issues. All calls setup, but no media passes because the contact IP is the physical LAN interface address of the computer not the tunnel virtual interface. I have verified that the interface metric is correct and windows does route split traffic correctly. It's something inside of the 3CX client that is incorrectly sending the wrong contact IP for RTP.Looking for help on this. #2 I just reproduced this using OpenVPN on my Windows 8.1 PC.I connected to my office and the 3CX Phone was using the correct interface to transfer both SIP and RDP via the OpenVPN tunnel. So here with OpenVPN it's working.Normally Cisco uses IPSec tunnels and not all of them have a local virtual IF. Can you see your IPSec IF in "Control Panel\Network and Internet\Network Connections"?If so go to advanced and move the Cisco VPN adapter to the top. Does that make a difference?If you don't have a virtual IF for your VPN I'm not sure if that will work as with VoIP it's more than normal routing since the client and the server need to be aware of their adresses as they are submitted during 5060 communication for them being able to create a working RDP stream in both directions..

Everything is working fine, but I have a problem with the 3CX Client. The 3CX Client is installed on a Windows 10 Pro machine, the 3CX Server is installed with the 3CX Debian ISO. The 3CX Client connects to the server, and everything is working fine. But after a few minutes, the client is unregistered. Bit101 Silver Partner Basic Certified #1 Hi togehter,we have the same problem like in this thread: can see that the 3CX Client is running in the background but we have no icon tray and no visible window.Reinstallation, programm kill in Taskmanager and reopen does`nt get success. Very strange is that theat 01:30PM afternoon it works suddenly.I have never seen this before.We use 3CX Windows Client 16.3.0.220 on Windows 10 (20H2)We also use the Sennheiser Epos plugin. The Epos Config Tool is also not visible.regards,beon 3cx_ettwein1.PNG 86.3 KB · Views: 7 NickD_3CX Community Manager Silver Partner Advanced Certified #2 This has nothing to do with the plugin, but rather with the fact that the client remembers it's last location on the screen.There are some cases when Windows might mess up the resolution for split second on boot, the moment the 3CX Client is launching, causing it to spawn off-screen.There is a nice trick to get it back, if you see it in the Task bar:Hold Shift and right-click on the Task bar icon of the 3CX ClientLeft-click "Move"Press any of the Arrow Keys on the keyboardThe 3CX Client Windows should snap to your cursor and you can drop it anywhere you wantGo to the Menu --> Exit ClientNow when it re-launches it should be fine. bit101 Silver Partner Basic Certified #3 Hi Nick,the problem is that we do not have the 3CX icon in the task bar. We can only see that the client is running as process in the taskmanager. Thats all. No window or icon at all. NickD_3CX Community Manager Silver Partner Advanced Certified #4 Ok, last idea I have then is to:Exit/kill the process completelyWith a Text Editor open %appdata%\3CXPhone for Windows\3CXPhone.xmlFind lines starting with "" and ""Set values for both to 0Save FileRe-launch SteveITS Silver Partner Advanced Certified #5 Is it up to date? Is 3CX being run as a standard user? We had issues like that in 2019-2020 with Sennheiser. IIRC they had a bug where it (Sennheiser) was trying to mess with certificates on open and couldn't as a standard user, so it was hanging. We spent quite a lot of time on it with them, and currently don't have the issue.Comments

2025-04-20#1 I'm a user, not an admin. I can't tell you the version as the client won't start anymore, but the executable is called "3CXWin8Phone.exe" and it was installed recently (approx. in May).I suspect it has something to do with the old problem of Visual C++ redistributables, as it happened around the time I did an update to Visual Studio. The following redistributables are installed on my system: 2005, 2005 (x64), 2012 (x64), 2012 (x86), 2013 (x64 - 12.0.40660), 2013 (x86 - 12.0.30501), 2013 (x86 - 12.0.40660), 2015-2019 (x64 - 14.27.29016), 2015-2019 (x86 - 14.27.29016).There is no 2015. I found a 2015 at it is version 14.0.23026. When I try to install it, I get an error 0x80070666 (another version is already installed).Any advice?Thanks,Soren #2 Hi Soren,The Windows client will install its own redistributables during installation, but it's a bit difficult to know what Visual Studio may have changed.By default, when installing the latest 3CX client as of today, you will see it installing:Microsoft Visual C++ 2015-2019Redistributable (x86) - 14.24.28127Hope this helps #3 FWIW it looks as if Microsoft are pushing a newer version of the 2015-2019 redistributable and you've listed the newer one.Out of curiosity I tried installing 3CX client ther updating the VCC redistributable and it didn't break it for me so it doesn't look like "DLL hell", but it might still be worth trying uninstalling the 2015-2019 (x86 - 14.27.29016) one, reinstalling 3CX and then reinstalling the redistributable.When you say "user not admin" you mean for 3CX don't you not Windows? #4 It's working at the moment again for some reason. Thanks for your reply. #5 Glad to hear Soren, we will mark this as solved then
