Ian, CPC: Information sent in the forward direction indicating the category of the calling party and, in case of semiautomatic calls, the service language to be spoken by the incoming, delay and assistance operators. The format of the calling party's category is shown below. OLI: Information sent in the forward direction indicating toll class of service. Identification of the originating line. Martin -----Original Message----- From: Ian Elz [mailto:ian.elz@ericsson.com] Sent: Tuesday, April 01, 2008 4:58 AM To: Paul Kyzivat Cc: iptel@ietf.org; DOLLY, MARTIN C, ATTLABS; sipping@ietf.org Subject: RE: [Sipping] draft-mahy-iptel-cpc Paul, My comments are made based upon the content of the latest draft (06). The introduction begins: "SS7 ISUP [4] defines a Calling Party's Category (CPC) parameter that characterizes the station used to originate a call and carries other important state that can describe the originating party. When telephone numbers are contained in URIs, such as the tel URI [2], it may be desirable to communicate any CPC associated with that telephone number or, in the context of a call, the party calling from it." Based upon this the current requirement appears to be to support the ISUP CPC/OLI. If the requirement is greater than this then that is a discussion that we should have before the draft is finalized. The issue with mutual exclusivity exists in the current ISUP implementations. If that limitation is to be overcome then that requirement also needs to be discussed. If we are to move from mutual exclusivity of values then we need to ensure that interworking back to ISUP is supported. The resolution of the overlapping cases as you have indicated may have to be at the discretion of the network operator.
