during VoWifi to VoLTE handover there is an attach process that happens before handover during which SGW and PGW pair is selected, during the handover the create session request is forwarded to that same SGW and PGW
@@fataldbz I think we need to keep the same PGW for HO of ims call from wifi to LTE coverage. How is the PGW selected? Is PGW info passed to MME (via HSS) and MME should get/select same PGW in DNS query?
