An incoming SIP-Q call may request one or more terminating features to be overridden at the called party, i.e. not to be invoked for that call. For example, an attendant making an urgent call for a particular user wants to terminate to the called party number and not be call forwarded to anyone else.
Any incoming SIP-Q call terminating to a Lotus Sametime Unified Telephony subscriber is checked for CF, DND and Call Pickup Override classmarks. When Override is indicated, the overridden feature(s) shall not be executed if active at the destination.
Older SIP phones/clients may not support the new feature overrides.
Currently, Lotus Sametime Unified Telephony subscribers can't be protected against Override requests.
Override Call Pickup
When an incoming call indicates Override Call Pickup and the destination belongs to a pickup group, the group members will not
be notified of this call. If a directed pickup is attempted, it will be rejected with appropriate response/cause value.
Override Call Forwarding
When an incoming call indicates override of CF (Call Forwarding), both phone-based and switch-based CF features (if any) shall be disabled for this call. The call will be delivered to the original destination, if possible.
Override Do Not Disturb
When an incoming call indicates override of a DND (Do Not Disturb) both phone-based and switch-based DND features (if any) shall be disabled for this call. The call will be delivered to the original destination rather than cleared or forwarded.
