Local Mode
If the WAN connection fails, the IP Phone loses communication with the
Main Office Telephone Preference Service (TPS). It then registers with
the MG 1000B and receives IP Phone services from the MG 1000B.
Features such as Personal Directory, Redial List, and Callers List are not
available when operating in Local Mode. When in Local Mode, the IP
Phone displays the message LOCAL MODE.

Using Test Local Mode

Use Test Local Mode to check Local Mode functionality (make and
receive IP Phone calls). Test Local Mode is useful when provisioning has
changed for an IP Phone on an MG 1000B Controller.
