Media Gateway 1000B
The Media Gateway 1000B (MG 1000B) telephone can operate in Normal
or Local Mode.
Normal Mode
The telephone registers with the Main Office and receives telephone
services from the Main Office. At any time during 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 by using the Resume Normal Mode command or by waiting
for ten minutes.
Local Mode
If the WAN connection goes down, the IP Phone loses communication
with the Main Office Terminal Proxy Server (TPS). The IP Phone then
registers with the MG 1000B and receives telephone 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 telephone displays “LOCAL MODE”.
Test Local Mode
Use Test Local Mode to check local mode functionality (make and receive
telephone calls). This is useful when provisioning has changed for an
IP Phone on an MG 1000B Controller.
1. Tap the Services soft key.
2. Press the Up/Down navigation keys to
scroll and highlight Test Local Mode.
3. Tap the Select soft key (the telephone
resets and registers to the branch office).
