OK, some codes work some don't depending on the trunk. Entering the code before the trunk selection is the very opposite of how it works with POTS lines on the unit.
Is it *81 or *67 to block caller id? *67 is standard and is what is in the user guide, but the system will not accept it.
In the guide *68 is listed as unblock where *82 is used as the standard.
Guess someone thought it was smart to make their own star codes.
