I know that someone else is going to have this problem, and I want to save them a headache.

By default, there are two options checked under the Troubleshooting section. DO NOT uncheck them (unless you really have to.)

The subheading reads "Potentially overcome compatibility issues with old/incompatible phones with these options" which implies that they should not be checked for new/supported phones.

This can affect caller ID, transfers and BLF and i'm sure other issues. So make sure you have those enabled, unless you really know that you shouldn't.

Hello @Rick S

Indeed these options should remain on for all extensions as they are on by default since the extensions creation. These options as you mentioned affect transfers, parking calls etc. and could cause a lot of issues if turned off. You should only turn these options off only for troubleshooting purposes or if asked by 3CX support.
