Enable Signalling

To enable users to make calls to a central number, the following settings must be configured in the UCServer administration.

The phone number set is then administratively assigned; users cannot change it themselves or disable the signalling. 

Open the UCServer Administration, go to "Signalling" and enable "Enable signalling" by ticking the box, then click on "Add...".

The "Select User" window will then open, where you can add the users for whom you wish to set up the signalling.
