  1. Split DNS - Draytek

    How is the 3CX FQDN (xxx.3cx.co.uk in your example) being resolved on the second PC? Test this using nslookup xxx.3cx.co.uk . This should also reveal which DNS server is being used by that second PC. If it isn't the DrayTek router, then the Split DNS entry for the 3CX must also be configured on...

  2. Emergency message recording and turning it off.

    So, what is the actual question? Is it perhaps a question of how to ensure that calls from specific extensions or devices are played only once or for a maximum duration? Yes, a CFD application can identify the caller and determine whether the call is being sent into an infinite loop within the...

  3. New trial - can't reset password

    @snewman77 Do you have console access to the system where the 3CX is installed? If yes, then look here https://www.3cx.de/forum/threads/adminzugang.121493/post-439234 and maybe use a translator. If it is a Windows-based 3CX installation, the procedure is similar. I can write it down here. There...

  4. Query Regarding SC 16 License Extension Limit

    To return to the original question: Yes, every set-up user counts. When I read this, the question arises: what type of call forwarding is being used for these users? All other 3CX entities - such as Ring Groups, IVRs, departments, and call scripts - are not counted for licensing. Call...

    Many thanks to everyone who makes this forum what it is, and congratulations to the winners.

  6. Update to

    Looking at your log, that doesn't seem right. First, 3CX v20u5B551 is installed, followed by 3CXv20u6B724. This implies that the previous version was either 3CX v20u4B487 (from late 2024) or a u5 beta. Either way, these are all far too old. But it's good that the problem could be solved so easily.

  7. Update to

    The log is very short; that can't be everything. But what stands out immediately is the incorrect system time. The speed is also striking; it takes far too long. Is the system underpowered (disk I/O performance, RAM, CPU power), or are there technical issues?

  8. Is there anyway to automatically block: Unidentified Incoming Call.

    I have to admit, I don't recognize these numbers and I have little desire to look up the IP addresses right now. I assume these are unwanted direct SIP calls appearing in the 3CX logs that are being reported. If that is the case, please read this at first...

  9. Security Alert: Update your Self-Hosted 3CX Deployment

    Thanks for the clarification. That made for a long night here in CEST yesterday. However, as a Silver Partner, we don't have many systems, and the process can also be automated (i.e. using PowerShell). All systems are now up to date.

  10. Security Alert: Update your Self-Hosted 3CX Deployment

    Thanks for the fix and for making it available so quickly. Is a apt update && apt -y dist-upgrade and reboot required (because some linux packages and the kernel are even waiting for updates)?

  11. Proxmox Autodeployment

    Hello @Kevin Attard Compagno, We currently have several 3CX installations running on PVE. I have a question: Is it an issue if we continue as usual and install 3CX on PVE using the 3CX ISO? As far as I know, there have historically been issues whenever a support ticket had to be opened with...

  12. CVE-2026-42945 Nginx

    Thank you for providing the nginx 1.22.1-9+deb12u7 package for the 3CX v20u9 rc. When will the package be released for 3CX v20 Update 8?

  13. CVE-2026-42945 Nginx

    Hello @KyriacosS_3CX, not really :\ I already read that the first time, so there is no need for me to read it again. If you read what @NikosT_3CX wrote yesterday, you will notice that his statement can be understood as if 3CX is still waiting for the corresponding update from Debian. That is...

  14. CVE-2026-42945 Nginx

    since 16.05.2026: https://lists.debian.org/debian-security-announce/2026/msg00189.html

    Congratulations to all the winners, and thank you to everyone who helps make this forum what it is.

  16. Custom call script and holidays

    It is probably because your CFD program in 3CX is not assigned to any department (with holidays). The holiday.cs checks the department of the call destination and determines whether it is a public holiday or not. Note: A program created with the CFD for a 3CX system always answers any call...

  18. 3CX V20 how to send logs to syslog server

    nice:

  19. Any way to get the EXTGUID of an Extension?

    3cx-xapi-get-user-extguid.ps1 $tcxurl="mypbx.mydomain.de" # needs port if not 443 $jsonauthbody = (@{ Username="100" # 3CX user, maybe email address Password="Super_Secret0815" # 3CX user password SecurityCode="" } | ConvertTo-Json) $LoginResponse =...

  20. Three different places to set codec priority?

    You forgot DECT and ATA ;) Each of these uses its own global 3CX parameter MLTACC_<MAC>.
