Scenario: Cell phone user is in a conference call and has subscribed to wireless re-connect service. The cell phone user gets dropped.
In this case, the re-connect announcement should not be played back into the audio conference (-> feature interaction problem).
Service Coordinator retrieves feature interaction policies (indicating that a media server should not be used) and notifies the Wireless Re-Connect application.
Wireless Re-Connect application:
Connects the conference bridge to a call park server instead of a media server.

Unique IMS Subscription
Each IMS User can have more than one Private Identity
E.g., a subscription can support multiple devices (sip phone, IPTV, …) and SIM cards
Each IMS user can have more than one Public Identity per Private Identity
Each Public User Identity is assigned exactly one Service Profile
But a Service Profile may be assigned to more than one Public User Identity
Example of multiple Private Identities:
IMS handset with USIM card (using personal Public Identity IMPU-1 and one Office Public Identity IMPU-2)
IMS WLAN card with soft USIM card (using WLAN Public Identity IMPU-3 and one Office Public Identity IMPU-2)
