The Overflow feature permits an overflow DN to be assigned to a Hunt Group. This DN is used as destination DN to which unanswered incoming calls are sent when the queue is full.
By assigning an Overflow DN, the administrator modifies the treatment of busy handling within the group, providing a fixed destination for routing the call.
Since Lotus Sametime Unified Telephony 18.104.22.168 the overflow destination of a linear
hunt group can not only be a local number (required in earlier releases and still required for other routing algorithms), but can be located in the SIPQ network. Any network routable number (with or without prefix digits depending on number modification rules) is accepted. For other destinations, Lotus Sametime Unified Telephony returns an error for an invalid number.
