Lotus Sametime Unified Telephony uses one of the following numbers as Number Identity.
Subscriber's Directory Number (Home DN)
This is the main number associated with the subscriber. The subscriber's Directory Number can be either a Public (E.164) or a Private (L2, L1, or L0) number.
The definition on whether the Home DN is a Public or Private number is part of the subscriber profile data:
If the subscriber's Type of Number field is set to Public, it means that the Home DN assigned to the subscriber is a public (E.164) number.
Otherwise, it means that the Home DN is a private (L2, L1 or L0) number.
External Caller ID
The External Caller ID
feature provides the subscriber with a second number which must be used for all external calls, incoming and outgoing.
This feature is useful, for instance, when the subscriber's Directory Number
(Home DN) is Private
(i.e. L2, L1 or L0 number). In this case, the subscriber's Directory Number
cannot be used for external calls.
This feature can also be used if the subscriber wants to hide his Directory Number
for calls to (or from) the public network.
Main Pilot DN
Starting with Lotus Sametime Unified Telephony 184.108.40.206, the administrator has the option to configure a subscriber that is an MLHG member to use the Name and Number of the Main Pilot DN
as the subscriber's identity for Internal and/or External calls.
Note that the External Caller ID
has higher priority than the option to use the Main Pilot DN for external calls. If the administrator wants the subscriber to use the Main Pilot DN
as identity for external calls, he/she needs to remove any External Caller ID
configured for the subscriber.
Default Home DN
Lotus Sametime Unified Telephony V5 introduces a new Default Home DN
which can be assigned to an endpoint.
calls to a SIP endpoint (SIP Trunking, SIP Private Networking or SIP-Q Private Networking), if the calling party does not have a Public
number, Lotus Sametime Unified Telephony will use the Default Home DN
(if configured on the SIP endpoint) as the calling party number.
BG Display Number
The BG's Display Number
is the default number that will be used to send to the public network in case Lotus Sametime Unified Telephony has no other public number available for a subscriber.
