Solved TLS SIP Trunk has broken after update

[jrenshaw]

Hi,
This morning our SIP trunk has stopped connecting and we think it's related to a recent update that has undone a previous fix
The same error message from my original thread has reappeared https://www.3cx.com/community/threads/hosted-by-3cx-tls-not-connecting-with-valid-settings.84672/
Many Thanks!

Hi @jrenshaw

We made a small change to the PBX to avoid having to mess with the OS so you will need to navigate to Security / Anti-Hacking and disable the option "Enable PCI compliance SSL/SecureSIP Transport and Ciphers (This will leave only TLSv1.2 enabled and may prevent old legacy phones and old 3CX Apps to connect remotely to your system). Requires SIP service restart (Go to Dashboard, Services, Select 3CX PhoneSystem 01 SIP Server and restart)."



Once you do please restart your SIP server service by navigating to Dashboard / Services. It should be OK after that
