Doesn't stop you having to add a link name every time you edit a user without one. It would make much more sense that if the link name was blank, chat was disabled for that user.
Making it a mandatory field is a PITA for general admin.
Okay, yes, the field is indeed mandatory. The good news is that when creating the extension, it gets filled in automatically.
You're referring to extensions created before V20. Yes, it would be great if 3CX added enable/disable parameter, but I believe the developers at 3CX have done an outstanding job, and sometimes, we have to choose our battles.
I think this is such a "minor" situation.
Anyway, that said, I've created a small script for you to run in the 3CX "Call Processing Script" to automatically fill in the "Link Name" field if it's empty.
Of course, you might say that it would be better if 3CX added the deactivation parameter, and I agree. But if 3CX has to choose between developing a new feature that offers more benefits or implementing a simple parameter to "disable" the "Link Name" field, I’d much prefer the new feature.

You can't say I'm not being honest 
You follow the same steps as described in the guide:
https://www.3cx.com/docs/intercept-call-example/
but instead, select "Dial Code" and choose a code of your choice to trigger it.
Once saved, you can "start" it by call the dialcode you haved set.
In my example, I chose *8*8
The action is limited to extensions :
