Upgrading the Media Gateway Boards

The Media Gateway boards are upgraded one after another. The Media Gateway
boards (except the Redundant board) are upgraded starting from the lowest slot
number. Following this, the Redundant board is upgraded.
Active calls on the Media Gateway board are dropped during the upgrade. However,
the predefined Graceful Shutdown period (and corresponding Service Change or
RSIP messages) minimize the amount of the dropped calls.
Depending on the options you chose in the 'Welcome Questionnaire' on page 167,
you can pause after the first Media Gateway board is upgraded (or after each Media
Gateway board is upgraded) and verify that the process is successful.
With the first Media Gateway board, as well as the Active SC board upgraded, you
can perform extensive testing of the new software in order to decide either to continue
with the Upgrade or to Rollback to the previous software configuration.
