Testing this on Yeastar Cloud but I assume it's the same on S-Series.
Right now, any extension on the system can pick up a ringing line for any other extension. Please add a function to restrict which other extensions are allowed to pick up an extension's incoming calls.
This is not good... consider the scenario of a mail clerk being able to intercept calls made to the CEO's direct line.
Call pickup works great, but we need the ability to specify who can use it for which extensions. Please add this feature.
