There has to be a way to add multiple phones at once to class of service. The double click in the class of service doesn’t work and I repeatedly have to make those assignments on larger systems. Doing it one at a time in the extension module is PAINFUL!
Otherwise, how are you using this module? In a typical system, most of the phones have the same CoS e.g. no restrictions except international destinations. There are a few extensions (doors, lobby, hall, etc.) that are greatly restricted. A few managers are allowed international calling. If you start by including all extensions in the ‘no international’ class, you only have to move a few phones to the other classes.
