MGCP Configuration
The switchover occurs immediately with a manual redirect. This command does
not switch the gateway to the backup Cisco CallManager server if you have the
switchback option set to immediate and the primary Cisco CallManager server is
still running.
To view the current configuration of a Cisco voice gateway, enter the show
ccm-manager command from privileged EXEC mode. Example 5-1 illustrates a
typical display that appears in response to this command.
