/mcpComments Supported in Unified Communications Manager SIP Headers Used for ID services including Connected Name and ID. This nonstandard, nonproprietary header gets included in the Standard Feature Scenarios anyway. Yes Remote-Party-ID +multiple-codecs-in-ans is introduced by Multiple codecs in the SDP answer feature. Yes Contact Remote-Party-ID Header This section describes the SIP Identification Services in the Unified Communications Manager for the SIP line, including Line and Name Identification Services. Line Identification Services include Calling Line and Connected Line Directory Number. Name identification Services include Calling Line Name, Alerting Line Name, and Connected Line Name. The Remote-Party-ID header provides ID services header as specified in draft-ietf-sip-privacy-03.txt. The Unified Communications Manager provides flexible configuration options for the endpoint to provide both the Alerting Line Name and/or the Connected Line Name. This section does not describe those configuration options; it only provides the details on how Unified CM sends and receives these ID services to and from the SIP endpoint. The Remote-Party-ID header contains a display name with an address specification followed by optional parameters. The display carries the name while the user part of the address carries the number. Unified Communications Manager 8.0(1) enables the Unified CM to route the localized and globalized forms of a calling number to the receiving endpoint, which is known as Calling Party Normalization (CPN). For example, when receiving a local call outside an enterprise in North America, it is desirable to display the familiar seven-digit calling number to the endpoint user (for example, 232-5757). To return a call to a local number outside the enterprise, the endpoint user typically dials an access code (for example, 9) to indicate dialing of an external directory number (92325757). This form of the calling number is referred to as the global or globalized number. The localized form of the calling number is presented in the SIP Remote-Party-ID header as the user part of the address. The globalized form of the calling number is presented as an optional SIP URI parameter. Although the Remote-Party-ID header is nonstandard, many vendors implement it, and it is included in most Cisco SIP products. Therefore, the standard section of this document includes it, even though it is effectively proprietary. The use of this header is not negotiated. Recipients should ignore it if it is not understood.
