;
; NOTES on UDP listeners
; - Address/port can be changed and reloaded
; - If address/port is changed for an enabled listener this will be destroyed and recreated
; - When an UDP listener is destroyed all channels using it will be dropped and
; all lines using it will be unregistered
; - If the only configured listener is 'general' this one will be the default one
; - After initializing the module will find for a default transport:
; 1: First search for a default listener whose name is not 'general'
; 2: Use 'general' if no other listener is set to be the default
