Have a Merlin Legend setup as PBX, secretary is setup with an MLX5 set as NON-operator. There are 2 incoming lines soon to be 3 or 4 which are on line pool 70. When a incoming call is answered by this set and a 2nd call is made incoming it rings other phones but not this phone. Can I set up this specific phone extension to receive multiple simultanuos incoming calls? Do I need to make it an operator with a different set other than MLX5? Or do I need to break up these lines into different pools?
