  1. Solved Certificate error Yealink?

    Just as a point of interest, we have a mixture of T40G and T46S phones. I have tested a number of each and it would seem that the T40G phones fail when attempting to update the phonebook (unless I have manually disabled 'Only Accept Trusted Certificates', whereas the T46S phones are updating...

  2. Solved Certificate error Yealink?

    You misunderstood what I wrote. I am saying that the 'only' thing to have changed with our setup is that I have upgraded to V18 from V16 a few weeks ago, and so is it a V18 related issue. It would be interesting to know if anyone is experiencing this issue on a V16 PBX.

    The following is a suggested 'work around' and not a 'fix' for the issue. Log on to the web GUI for the phone. For a factory reset phone use the default log details, and for a provisioned phone use the 'phone web page password' which can be copied from the 3CX Phone System Management Console...

  4. Solved Certificate error Yealink?

    The phone I have the issue with is a T40G. It was at firmware v 76.84.0.95 and I even tried downgrading the firmware to v 76.84.0.35 as well, without success. The 'only' thing that springs to mind is that we have upgraded our PBX to v18 (from v16) since I was last able to provision a phone...

    Hi Thanks for the link. I was hoping it might explain my issue as well with provisioning a Yealink phone today. I have entered my three certificates into the Certificate Decoder referred to. All mine are in date! 1. PBX FQDN 01-Nov-2021 2. R3 15-Sep-2025 3. ISRG Root X1 30-Sep-2024 Thanks.

  6. Solved Certificate error Yealink?

    Hi I've been battling with the issue of re-provisioning a T40G all day. The solution I have discovered in the last half hour is to log onto the web GUI of the phone, go to the Security tab, select Trusted Certificates and set 'Only Accept Trusted Certificates' to Disabled. Once the phone was...

  8. No audio heard from Nokia 5.3 for first 5 to 20 seconds of call

    Hi Having been busy on other tasks Friday, I've come back to the phone issue today. The version of the 3CX Android app does not seem to have changed, even though the phone is configured for Beta releases. I have performed some test calls and it has only had an issue with the audio on a couple...

  13. 3CX Hosted PBX gone offline. Help!

    I trialled it last year using on-premises 10 year old laptop running Windows 10 to host the PBX. Whilst it worked well internally, I had issues with the firewall check failing on the full cone test. Also, most of our staff are remote, and now with Working From Home, nearly all our staff are...

  15. 3CX Hosted PBX gone offline. Help!

    Hi Nothing to report other than a comment from John at 12:16 saying 'Should not be too long now, and I will be able to inform you'. I'm still offline and feeling very frustrated. I sold the idea of 3CX to the directors last year and we have just managed to get out of our phone contract and...

  16. 3CX Hosted PBX gone offline. Help!

    Hi I currently have a private chat open with JohnS_3CX as of 10:06 this morning. He responded back to me at 10:12 saying they were going to check and get back to me. That was the last communication. I can ping successfully the IP address, so I was guessing that the 3CX PBX services had...

    I'm currently watching the final day advanced webinar training with Nick and was logged into the PBX Dashboard and click on the Log Activity link! The PBX seems to have crashed. SIP phone showing No Service. Web interface not connecting. Because the PBX is hosted by 3CX, I have no access to...
