Chapter 5: G150 Media GatewayTelephone Support
Telephone Support
In sub-tending mode, the G150 registers its trunks and analog handsets on the Communication
Manager, representing them as directly connected IP end-points on Communication Manager.
IP phones at the G150 site are directly registered to the Communication Manager, by-passing
the G150.
Telephone Support in Survivable Mode
In survivable mode, G150 acts as a stand-alone sytem where all trunking and telephone
functions are provided locally. The G150 becomes a gatekeeper and handles calls using its own
local call routing/dial plan configuration. In survivable mode, G150 provides the following
features to its registered users and directly connected telephones while attempting to re-register
to the Communication Manager:
●
CLI/ANI Display (IP phones only)
●
Hold
