How to release server license or change Asterisk server
In case you need to change or replace already registered Asterisk server you can release the license associated with registered Asterisk server and then reuse the same license to register new Asterisk server (hardware replacement, Asterisk server replacement etc.). The server license release can be done easily with a single press of a button within the Visual Dialplan.
Open Preferences dialog (Edit –> Preferences … from the main menu) and on the left side of the dialog you will get a list of registered Asterisk servers.
Simply select one of registered servers and edit/modify parameters for that server (opened in the right part of the dialog) or click on the X icon (above the list of registered servers) to delete the server and reuse the licenses associated with that server to register new Asterisk server.
