Literal MAC - Using an Android API, the Zebra Voice Client interrogates and inserts the mobile device’s MAC address into the Zebra Voice Client configuration. Replacing the mobile device requires the Administrator to modify the configuration. The replacement device then has the same configuration as the previous device.
Pseudo MAC - The 12-character MAC string is a simple unit identifier in the PBX. The device can be replaced without Administration intervention. The pseudo-MAC does not represent the actual device MAC address. To place a replacement device into service, set the Zebra XML configuration to match the existing string defined in the PBX.
