Media Gateway 1000B
A Media Gateway 1000B (MG 1000B) IP Audio Conference Phone can
operate in Normal or Local mode.
Normal Mode
The IP Audio Conference Phone 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 10 minutes.
Local Mode
If the WAN connection is lost, the IP Audio Conference Phone loses
communication with the main office Terminal Proxy Server (TPS). The IP
Audio Conference Phone then registers with the MG 1000B and receives
telephone services from the branch office. When in Local Mode, the IP
Audio Conference Phone displays "LOCAL MODE".
Test Local Mode
Use Test Local Mode to check local mode functionality (make and receive
telephone calls). Test Local Mode is useful when provisioning has
changed for an IP Audio Conference Phone at a MG 1000B Controller.
