Use the SIP Subscription Status window to monitor active SIP subscription status for a list of SIP endpoints.
From the SBC main screen, navigate to Monitoring > Trunks and Subscribers > Registration > SIP Subscription Status. The SIP Subscription Status window displays.
By default only ten entries are displayed in a view. You can choose the number of entries to be displayed under the Show entries drop down box.
The active SIP subscription status can be checked for each Address Context or for all the Address Contexts. Use the drop-down box to select the desired Address Contexts.
