Using Media Gateway 1000B
The Media Gateway 1000B (MG 1000B) provides a means of extending
CS 1000 Release 4.5 features to one or more remotely located branch
offices using the Branch Office feature. A branch office is a remote
location in the network where IP Phones, PSTN access, and TDM phones
are located. Contact your system administrator to see if these functions
are available for your use.
The Media Gateway 1000B (MG 1000B) phone can operate in Normal or
Local Mode.
Normal Mode
The phone registers with the Main Office and receives phone services
from the Main Office. At any time while using Normal Mode, you can
check Local Mode functionality (make and receive calls) by enabling
Local Mode and returning to Normal Mode. After testing, you can return to
Normal Mode (see “Using Resume Normal Mode” on page 139) or wait
for 10 minutes.
Local Mode
If the WAN connection goes down, the IP Phone loses communication
with the Main Office TPS. It then registers with the MG 1000B and
receives phone services from the MG 1000B. Features such as Personal
Directory, Redial List, and Callers List are not available when operating in
Server
