A similar thing we can say about VoLTE Conferencing.

Call conference call flow in volte. The call flow will be A calls C then B calls A followed by A confere. In any cellular network whether it is GSM CDMA or LTE there are two main parts viz. VoLTE uses IMS signaling to setup voice calls.

P-CSCF maintains the security associations between itself and the UE. Voice over LTE VoLTE is the standard for voice call setup in LTE networks. SDP Codec Selection and QoS Signaling in an IMS call.

Sample RTP and RTCP messages are also shown in the flow. This Video is all about SIP Signaling Codec Negotiation happens in VoLTE where we will go thru Complete Mobile Originating Mobile Terminating call flow for VoLTE to VoLTE Calls. It is directly connected to the VoLTE device UE over SIP protocol.

4 The conference initiator then uses the refer procedure to add more users to the conference. A PCSCF SCSCF Origination AS to execute originating service if provisioned SCSCF after service execution BGCF MGCF CS. Call routing via the BGCF is also illustrated.

VoLTE conference call is a technology by which more than 2 UEpersons can communicate each other within the same call. It indicates the voice call setup request is being notified to the recipient. The VoLTE call flow procedure covers messages exchanged between UE or LTE mobile LTEEPC entities and IMS entities.

1 UE NW Initial RRC Connection Establishment. UE Receives SIP INVITE Message. The conference initiator then uses the refer procedure to add more users to the conference.
