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

1. Log in to the router.
2. 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
   
   

3. Repeat step 2 until the number of emergency contexts is 0.
4. 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.
5. Repeat 2 until no contexts are active or you decide to force a shutdown of the virtual BGF.
