    Hello,

    I think the latest sp4 update has broken my multiple sip trunks. I would like to downgrade to sp3. How do I do that ? The real question is where can I download a 3cx v15 sp3 installation file ?

    Install an image of 3CXPhoneSystem15.exe with SP3, if you have kept one, otherwise send me a PM to send you a copy, and restore a backup you might have kept of your configuration with SP3. Downgrade of configuration from a SP4 backup may not work

    Hello @choimarc

    Could you tell us a bit more about your configuration and what the issue is? maybe there is an easier solution rather than un-installing and re-installing
