Is there permission we can control - that does not allow agents to set their own phone properties - like select phone or deselect phone.

Try removing Telephony > Phone >  Assign to keep them from assigning phone and Telephony > Station > DisassociateSelf to keep them for removing it.  Also, removing this makes it so they can't go On Queue if they don't have a station.

Hello Sujatha

Did you managed to resolve this issue?  If not I would certainly recommend raising a case with customer care to look into what is causing this.  I believe the permissions Robert shared should be the ones related to the issue you were experiencing.
