Managing Emergency and Non-Emergency Call Traffic Prior to
Upgrading
Before you upgrade a router that you are using for voice traffic,
monitor call traffic on each virtual BGF. Confirm that no emergency
calls are active. When you have determined that no emergency calls
are active, you can wait for non-emergency call traffic to drain due
to the graceful shutdown, or you can force a shutdown.
To check the status of emergency and non-emergency calls
Log in to the router.
Enter the following operational
mode command to display the total number of active contexts and the
number of active emergency contexts:
user@host> show services pgcp statistics
gateway bgf-1 extensive match | contexts
Contexts : 11 / 6000
Emergency contexts : 0
Repeat Step Step 2 until the number of emergency contexts is 0.
As a precaution, also query the gateway controller
to confirm there are no active emergency calls. Refer to the documentation
for your gateway controller for details.
Repeat Step Step 2 until no contexts are active or you decide to force a shutdown of
the virtual BGF.
