Hi Thanks for your feedback
Go ahead and submit them here. Important to specify the version so we can report back when and in which version they are fixed.
You can change the repository if you want by adding "beta" to 3cxpbx in the url
echo "deb http://downloads.3cx.com/downloads/3cxpbxbeta/ /" | tee /etc/apt/sources.list.d/3cxpbx.list
When you do this you will get the next update that will be final. (We are making another beta update today).
Update to this.
Check to see whether the issues you found are still present in this version.
