Unsolicited CallSubscriptionEvent

BroadWorks distributes the CallSubscriptionEvent event as soon as BroadWorks detects a failover on the subscribed user. CSTA Connector tests the call parties reported in the event against the list of call parties on the given user that are kept in CSTA Connector.

All parties that are not reported in the the CallSubscriptionEvent event are cleared from the CSTA Connector memory and the CSTA Event Connection Cleared message (cause: SwitchTerminated) is sent to all Clients (T-Servers).

Note: The CallSubscriptionEvent event supplies the party information for a specified agent. Other agents involved in the same call are not affected as they may have received a dedicated CallSubscriptionEvent event.
