Number and Name Delivery is an automatic feature of Lotus Sametime Unified Telephony. Together Number and Name form a user's identity. The identity of the calling party is delivered to the called party and vice versa, the identity of the called/connected party is delivered to the calling party.
The display number modification feature ensures that the digits appearing in the display of the endpoint or application represent a dialable number, in the format required to dial back the calling, called, or connected party.
The identity of a user that is provisioned as a Lotus Sametime Unified Telephony subscriber contains
Internal Name and Internal Number (aka Subscriber DN) for internal calls.
The Subscriber DN is delivered as Internal Number unless the subscriber is is provisioned to use a different Displayed Extension Number
for internal calls.
External Number (aka External Caller ID
) for external calls. If no External Caller ID
is available then for external calls:
If the subscriber is a MLHG member and it is provisioned to use the Main Pilot DN for external calls, then the Main Pilot DN is used, provided it is an E.164 number.
If the Subscriber's Directory Number is a Public DN (flag configured on the Subscriber), then this DN is used.
If the called party is in the public network accessed via a SIP Trunking endpoint with Default Home DN configured, then that SIP Trunking endpoint's Default Home DN is used.
If none of the above return a useful E.164 number, then the BG Display number is used.
Delivery of a Lotus Sametime Unified Telephony subscriber's identity depends furthermore on the configuration of the features Number Permanent Presentation Status
and Name Permanent Presentation Status
for that subscriber. These features may restrict the presentation of a user's internal or external identity towards other users.
The identity of users that are not provisioned as Subscribers in Lotus Sametime Unified Telephony may also be delivered by the endpoints that deliver the incoming call or terminate the outgoing call. Lotus Sametime Unified Telephony's ability to look for these identities can be provisioned via the Privacy
feature that is provisionable on endpoint profiles for SIP Trunking endpoints. Possible values for Privacy are:
Basic: do not look for or send identities in the SIP P-Asserted-Identity header field. The only identity being transferred is the calling party's identity in the SIP From header field.
Full: look for and send identities in the SIP P-Asserted-Identity header field. Calling, Alerting, Busy and Connected party's identities will be delivered and received.
Full-Send: do not look for, but send identities in the SIP P-Asserted-Identity header field.
Full-Receive: look for, but don't send identities in the SIP P-Asserted-Identity header field.
In case no Name identity was transmitted by the remote party, Lotus Sametime Unified Telephony will not assign any name to the party.
