The Called-Party-Address AVP (AVP code 832) is of type UTF8String. It holds the address (SIP URI, Tel URI or URN) of the party to whom the call is addressed.

For IMS charging (except for SIP Register and SIP Subscription transactions), it holds the address of the party (Public User ID or Public Service ID) to whom the SIP transaction is posted. The Called-Party-Address AVP shall be populated with the SIP URI or Tel URI contained in the Request-URI of the outgoing request. For a registration procedure, this AVP holds the party (Public User ID) to be registered. In this case, the Called-Party-Address AVP is obtained from the "To" SIP header of the SIP Request. For a subscription procedure this AVP holds the address of the resource for which the originator wants to receive notifications of change of states. In this case, the Called-Party-Address AVP is obtained from the outgoing Request-URI of the SIP Request.

For VCS charging, it holds the address (URN is not applicable) which identifies the party to which a voice call is destined after processing by the Proxy Function. It is converted from the circuit-switched Called Party Number as per TS 29.163 [234] for the Request-URI header. For a mobile originating call, this AVP contains the Called Party Number after processing by the Proxy Function (e.g. number normalization).
