The CIS (Calling Identity Services) are a collection of features related to call related Identity Management. The delivered Number and Name form a user's identity and can be presented to the called or calling party. The information may be updated as the call progresses.
The format of the number identity of a user (Subscriber or Endpoint) to be presented to another user (Subscriber or Endpoint) can be controlled via the Display Number Modification tables of Lotus Sametime Unified Telephony.
Supported SIP Headers
For internal and external calls to a Lotus Sametime Unified Telephony Subscriber, Lotus Sametime Unified Telephony uses the P-Asserted-Identity
header field in SIP provisional and final responses to convey the identity of the called/connected party.
Not all SIP phones and endpoints may support this header field and may end up keeping the dialed number on the display.
For internal and external calls from and to SIP Trunking endpoints (gateways, applications, …), those SIP Trunking endpoints that support the P-Preferred-Identity
header field rather than the P-Asserted-Identity
header field, will receive the internal or external identity in this header field by provisioning the Send P-Preferred-Identity rather than P-Asserted-Identity
attribute on the SIP Trunking endpoint. However, Lotus Sametime Unified Telephony will always ignore received identities in the P-Preferred-Identity

Number and Name Delivery
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.
Number Permanent Presentation Status
Number Permanent Presentation Status indicates the default presentation setting ("Allowed" or "Restricted") of a Lotus Sametime Unified Telephony subscriber's number identity, which is used for the Number and Name Delivery. When the subscriber originates a call, it is used to determine whether or not presentation of the number of their identity to the called party is restricted. When they are called, it is used to determine whether or not presentation of the number of their identity to the calling party is restricted.
Name Permanent Presentation Status
The Name Permanent Presentation Status feature describes a subscriber’s default Name Delivery behaviour in the Number and Name Delivery context. When the subscriber originates a call, it is used to determine whether or not presentation of the name of their identity to the called party is restricted. When the subscriber is called, it is used to determine whether or not presentation of the name of their identity to the calling party is restricted.
Outgoing CID Suppression and Delivery Per Call
The forced Outgoing CID (Caller ID) Suppression and Delivery Per Call feature allows subscribers forcing either delivery or suppression of their calling identity (name and number) parameters for a particular call.
Anonymous Call Rejection
The ACR (Anonymous Call Rejection ) feature provides subscribers the capability to reject calls from parties who have a privacy feature active (such as caller ID blocking) that prevents the delivery of the calling number to the called party.
The Distinctive Ringing feature provides the ability for subscribers of a BG to hear different ringing indications for internal (within the same Business Group) and external calls (different Business Groups).
Directory Number Announcement
The DN (Directory Number) Announcement feature permits callers to determine the DN of the line from which they are calling.
Business Group Department Names
The Business Group Department Names feature permits a business group subscriber to be associated with a specific department. The department name can be delivered as an alternative to the calling or connected party name.
Malicious Call Trace
The Malicious Call Trace feature provides subscribers the capability to generate an automatic trace of the last call received. Subscribers typically use this feature in response to malicious, harassing, or nuisance calls, in order to provide a trace over time of such activity.
