The Serial Ringing feature provides subscribers the capability to be sequentially rung at a series of locations. This is especially useful for those whose job duties require them to be in or around many different work areas throughout the day.
This feature optionally includes the ability for the caller to instantly transfer to the callee's voice mailbox, rather than waiting for the call to progress through all locations to do so.
The administrator assigns the Serial Ringing feature to a subscriber, then associates it with one of the user's DNs, referred to as the main DN. After this step, either the subscriber or the administrator creates a screening list, known as a Serial Ringing List, that contains up to six DNs. These DNs represent the additional locations that ring when an incoming call arrives at the main DN, and the sequence in which they are rung. To allow control from the endpoint, the administrator has to create the corresponding Feature Access Code.
After entering this Feature Access Code, the subscriber hears an announcement that provides the feature name, its current status (active or inactive), and the number of DNs currently on the list. Lotus Sametime Unified Telephony then prompts the user to specify one of the following actions to perform:
Activate or deactivate the feature
Hear the DNs that are currently on the list
Add or delete DNs to and from the list
A confirmation tone or announcement is provided to acknowledge the activation. If the subscriber's serial ringing list is empty, Lotus Sametime Unified Telephony prompts the subscriber to enter DNs into the list. As soon as a valid DN is entered, the feature is activated.
After the feature is activated, incoming calls cause the main DN to ring. If it is not answered in the configured ring duration interval, the next destination DN is rung for its configured ring duration interval. The first DN to answer is connected.
OpenScape Voice uses the subscriber's dialing characteristics, rather than the caller's, when it sets up calls to the numbers in the Serial Ringing List.
If there is no answer after all destination DNs are rung, the call is then routed to one of the following:
The user's station Call Forwarding - Don't Answer destination (if defined)
An intercept announcement
If there is no answer at a given destination DN, Lotus Sametime Unified Telephony can optionally provide an intercept announcement before attempting the next number in the list. The options are as follows:
An announcement that keeps the caller apprised of the call's progress - for example, “Trying to reach the user at a different number.”
An announcement that provides the above information, and also gives the option for the caller to press a digit to be instantly routed to the called party's voice mailbox.
The Simultaneous Ringing feature is similar to this feature, but it rings several locations at the same time.
How to Provision a Subscriber for Serial RingingParent topic: User Mobility
This procedure describes how to configure Serial Ringing at the feature profile or subscriber level. Feature profiles, in turn, can be created and configured at the switch level or the BG (Business Group) level. At the subscriber level, the previously assigned feature profile can be overwritten to selectively enable, disable or modify the feature configuration for the particular subscriber. Those subscriber-level modifications effectively disconnect the individual service configuration from the underlying feature profile: a subsequent Reset Subscriber Lines on the feature profile will not influence a disconnected subscriber's service configuration.
