  2. Tunnel instability between 3CX server and 3CX SBC

    Hi, I have some reconnections between the 3cx server and the 3cx sbc, about 1 to 4 times per day. Each time, the server, or the SBC, complains about a keep-alive timeout, and stop or restart the tunnel. We could think that it could be a network lag, but I managed to find that during this time...

  3. Current Android Beta: no connection over Tunnel

    Hello, I have an android phone where I use the 3cx app. Whenever in the local lan (wifi) it works. However when I am not in the local lan it does not connect (Waiting for network).

  4. Idea's for Moving from on premise to Cloud

    We have 3 separate clinics. We tried 3cx at one with an onsite PBX and like it. We are looking at moving our pbx to the cloud so that all offices can point to the same one.

  5. Can we disable IPv6 in mobile app ?

    Hello Community. I am a newbie here evaluating 3CX. I've noticed that the latest 3CX app (15.5.15.388 on iOS 11.4) is using IPv6 while on 3G/LTE connectivity. Seems there is no parameter in settings available to force the app to stick on strict IPv4. Is this per design ? Because it brings...

  6. 3cx Google Cloud - LAN Registration Exception

    Hey All, I've got started with the GCE version of 3cx, purely as we have multiple sites it makes sense. I'm going to restrict the FW on google to limit non-tunnel protocol traffic to just our static IP addresses. However, I did have to also un-enable Extension > Options > Disallow use of...

  7. Issues with SBC - "Too long inactivity" on TCP connection every few minutes

    Hi All - Running into an issue with a new deployment of 3CX SBC on Debian 9 that we are testing in a remote office. The tunnel seems to establish itself ok, and even logs that it is sending and receiving keep-alives, but every few minutes the tunnel disconnects. The log below is from my...

  9. Audio delay

    Hi all. We have a client that utilises a hosted 3CX system that we host for them. Call audio quality is very good, but there is an obvious delay in the audio. You ask a question and there is a delay for them to respond, constantly talking over the top of each other etc. If feels like a 0.5 -...

    3CX Presence with 3CX Tunnel

    Hi, Has there been any progress in including the required presence information into the chosen 3CX Tunnel port, rather than having to leave port 443 or 5001 exposed to the Internet? I can see related posts to this in the knowledge base, dating back to 2015, but wondered where this sat within...
