  1. Polycom VVX 301 Random Restarts

    Thanks for the reply! Yeah, it's right on the line, if I had like 6 or more I would definitely use an SBC. This is a weird problem and incredibly annoying to debug when I only have a few minutes to review settings before the phone will restart again. I know it's network-communication related and...

  2. Polycom VVX 301 Random Restarts

    So I think it's just that Polycom phones don't play well with STUN and multiple phones on the same network. Once I add three or more phones, the restarts start and become more frequent with subsequent phones, however, having only two is solid! I have read other posts of users with other...

  3. Polycom VVX 301 Random Restarts

    My PBX is hosted on AWS with a static ip.

  4. Polycom VVX 301 Random Restarts

    Guess that did not fix it :( and now the other phones are back to restarting randomly again. I can confirm that a phone will NOT restart during a call. It will however popup: "NAT IP Changed" and then immediately after the call ends restart.

  5. Polycom VVX 301 Random Restarts

    So to check all my bases I cleared my firewall rules and recreated them from scratch. That seemed to have helped as the 3 phones were then solid and stopped restarting :) Which is weird since the phones worked and could make calls, you would think the phone just wouldn't connect and not keep...

  6. Polycom VVX 301 Random Restarts

    No updates are available under updates, it says "Your system is up to date". Checked the template again, still version 96893. Yeah, that was my next method to troubleshoot this, i'm going to bring the phones to my home tonight and see if they do the same thing. What's weird is we currently use...

  7. Polycom VVX 301 Random Restarts

    I have factory reset all phones before provisioning. They are all VVX301's. To be sure, I once again factory reset all phones and reprovisioned, the issue persists. I changed up the order of the phones I provisioned and oddly the first phone I provision seems the most stable (doesn't restart but...

  8. Polycom VVX 301 Random Restarts

    No, they make a chime sound and then they display "Restarting Phone". I have tried both POE and an AC adapter. It's not a hardware issue as they only start restarting after provisioning, before provisioning they do not restart which makes me think there is some phone setting or other possible...

  9. 3CX and TLS SIP Trunks - Any working?

    There was one poster today that claims Telnyx works with TLS, I haven't tried it. https://telnyx.com/products/sip-trunking

  10. Polycom VVX 301 Random Restarts

    I am running a test environment of a cloud-based 3cx with three Polycom VVX 301 phones connected to it via STUN and running firmware 6.1.2.1127. All the phones can call each other and can make and receive outside calls. Everything is working great except... After provisioning the phones, two of...

  11. 3CX and TLS SIP Trunks - Any working?

    From my searches in this forum and online, I am seeing a lot of users unable to use TLS with their SIP trunks (including Twilio, Plivo, DIDLogic...) and it appears that it's because 3CX doesn't allow wildcard root certifications. My question is: are there ANY SIP Trunks that work with 3CX AND...

  12. Remote extension can't answer incoming call

    SOLVED! I went through the setup steps again for the VVX series from 3cx "How to Configure Polycom VVX Series for 3CX " Under step 1: "Ensure that the phone is running the latest UC Software 6.1.2", I was actually running the latest firmware which is 6.2.0.4023. I downgraded to 6.1.2.1127 and...

  13. Remote extension can't answer incoming call

    Changed the ports, no difference.

  14. Remote extension can't answer incoming call

    They have not been assigned unique ports, I believe they both use the default port of 5060. Both extensions have this issue, i cannot answer a call on either set. The only call i can answer is from the softphone app on my cell to either of the hardlines. Hardline to hardline is where the issue is.

  15. Remote extension can't answer incoming call

    I am brand new to 3cx and testing a setup. I have 3cx running in the cloud on AWS and have Polycom VVX301 phones. I set up two test extensions via STUN. I can call one extension from the other and the extension rings however I cannot answer the call by either picking up the headset, answering...
