Filter Cisco Voice Gateways

You can filter the listed Cisco Voice Gateways in the Voice Gateways view based on the following attributes:

• Operational State
• IP Address
• Protocol
• Call Server

You can create filters for each of the listed attributes to view only the required voice gateways.

To filter the Voice Gateways view:

1. Right-click any of the listed attribute columns of one of the voice gateways listed in the Voice Gateways view and select Filter.

2. Select one of the following filters:

   • Equals this value: filters and lists all the voice gateways that have a value that is equal to the value of the column that you selected.
   • Create Filter: opens the Filter dialog box. This dialog box helps you specify a string and select options to perform filtering based on the string specified.
   • Is not empty: filters and lists all the voice gateways for which the selected column is not empty.
   • Is empty: filters and lists all the voice gateways for which the selected column is empty.
   • Not equal to this value: filters and lists all the voice gateways that do not have the value in the column that you selected.
     
     The filtered list of voice gateways appears in the view.

   You can also filter the voice gateways by right clicking the attribute column headings and selecting Filter and one of the following options:
