C.2 Interworking ISUP to SIP
29.1633GPPInterworking between the IP Multimedia (IM) Core Network (CN) subsystem and Circuit Switched (CS) networksTS
Table C.2.1 shows the mapping of a Calling party’s category received in an ISUP IAM to a "cpc" URI parameter within tel URI or the userinfo part of SIP URI with user="phone" in the P-Asserted-Identity header. When the Calling party’s category parameter value "operator, language x" is received the O-MGCF shall generate an Accept-Language header field with the value that corresponds to language x.
