Figure A.9-1: CONF interworking signalling flow in case of an active session between NGN and PSTN
UE-A is in an active voice session with a PSTN/ISDN TE (SIP dialog with Call-ID, to-tag and from-tag between UE-A and MGCF). It then creates a conference and invites the PSTN/ISDN TE to the conference by sending a REFER to the conference focus, which invites the PSTN/ISDN TE to the conference by sending an INVITE which includes the Replaces header to the MGCF. The MGCF confirms the session, switches the existing information channel to the new RTP session, and terminates the session which is replaced.
NOTE: The example given in the figure above assumes that the INVITE request sent from the UE and the INVITE request sent from the AS/MRFC are routed to the same MGCF.
1. – 3. UE-A initiates a voice session with a PSTN/ISDN TE by sending an INVITE to the MGCF.

Annex B (normative):
SDP a=content attribute "g.3gpp.conf" value
B.1 Introduction
This annex provides the IANA registration information for a new value, g.3gpp.conf, for the SDP a=content media-level attribute defined in RFC 4796 [40]. The attribute value is used indicate that an SDP media description is associated with the conference service
Editor’s note: [PC_VBC, CR0133] The following parameter should be registered immediately on approval of this specification, and the registration in error removed from "att-field (media level only)" table.
B.2 New value
IANA registration table: "content SDP Parameters" table of "Session Description Protocol (SDP) Parameters" registry
SDN name: g.3gpp.conf
Description: Stream associated with the 3GPP conference service.
