Extension Manager provides extension status, control, and configurations to Zebra Voice Clients using secure communications. Zebra Voice clients communicate directly with the PBX using the configuration received from the Extension Manager. The Extension Manager does not communicate with the PBX but it manages which extensions are provided to Zebra Voice client and controls the extensions that are available for other mobile devices. The Extension Manager must be configured with the PBX extensions to enable this functionality.
The below diagram illustrates the communication flow between the device, Extension Manager, and PBX.
