Additional Admin users
On both S and P-series I think there should be the ability to create additional admin users for maintaining the system but without the need to have a telephone extension assigned to these users. A maintainer or even a customer may have designated people to look after their system but they don’t always need a phone assigned to them. It would be useful if these users could have custom rights rather than full blown admin rights. An audit of changes made by them would be also very handy to track any issues.
