A VOIP Service Provider will typically have its subscribers register with the Service Provider’s
VOIP service server before starting a subscriber’s service. Often, an ISP will require the
registration of the MAC addresses of any devices directly connected to their network. Allowing
a subscriber to change the gateway device’s MAC address can be useful if a scenario similar to
the following occurs:
The subscriber travels away from home without bringing the gateway device with him or her.
At the destination location the subscriber has access to another gateway device and wishes to
access VOIP service from the Service Provider.
The subscriber experiences troubles with the gateway device, and the Service Provider sends
the subscriber a replacement unit with a different MAC address.
