  1. Solved Extensions constantly register/unregister

    @YiannisH Thanks! I can confirm that installing NTP resolved the issue for me. Another clue that this may have been time related was that the performance graph in the Dashboard was sometimes drawing loops or circles, rather than being a continuous function. Might I suggest including NTP...
  2. Solved Extensions constantly register/unregister

    Anyone have any other ideas on this?
  3. Solved Extensions constantly register/unregister

    Also, does anyone know if the Debian 8 version of the 3cx ISO is still available somewhere? I'd like to try moving back to Debian 8 and see if that helps.
  4. Solved Extensions constantly register/unregister

    Sorry, my attempt to anonymize the packets with TraceWrangler (default setings) seems to have been overzealous. I've scaled back the settings now and I think the relevant packets are no longer being "sanitized". You should be able to see the SIP traffic between the phone (192.168.25.100) and...
  5. Solved Extensions constantly register/unregister

    Sorry this took so long. Here's a trace (run through TraceWranger to randomize IPs/MACs/etc...). During this time I made an edit to the extension on the server and saved it (which always makes the extension show registered for a moment). Saw the extension go to unregistered in the view, and...

    Thanks for your response. That's correct--latest version. I originally downloaded the PIAF version from pbxinaflash, but it seems to be identical to the 3cx download. It is Debian/GNU Linux 9. Here's the VM settings (current and some older things I've tried): Generation 1 RAM: 4GB...

    Sorry, another piece of information I should have included, this is on Debian. So far, I haven't been able to find anything noteworthy in the system logs.
  9. Solved Extensions constantly register/unregister

    Greetings, I am working on a new 3cx installation. I'm having a problem where all extensions are constantly registering/unregistering (this includes system extensions). I'll start the server up--everything will look good. I was able to briefly have a conversation between 2 extensions. But...
